GM47 Triceps Press / Wholesale, Bulk Supply & OEM for Commercial Gyms, Strength Studios and Rehabilitation Centers

A Selectorised Machine for the Long Head of the Triceps

The GM47 Triceps Press is a single-purpose selectorised machine for the triceps brachii, built around a seated pressing movement with a defined arc. At 1554 × 1068 × 1296 mm and 206 kg, it is a commercial-grade unit intended for facilities where controlled elbow-extension loading is the requirement.

The specification sheet supplies four values: the model designation in English and Chinese, an illustration of the machine, the dimensions, and the weight. These are sufficient to determine the machine’s category, but they do not describe the movement pattern, the stack specification, the adjustability, or the frame construction. Buyers should request a complete specification sheet before quotation.

The distinction between this machine and a cable triceps pushdown matters. A cable movement requires the user to control the bar path independently in two planes. The GM47 defines the movement path through a linkage system, which removes that control requirement and produces a repeatable movement that members can learn in one instruction. For a commercial gym, that repeatability is the reason selectorised machines remain on the floor: they do not require supervision.

The triceps brachii has three heads — the long head, the lateral head, and the medial head. The long head crosses the shoulder joint and is influenced by arm position. The GM47 illustration shows an overhead or angled arm position, which places the long head under stretch during the eccentric phase and produces a different training stimulus from a standing cable pushdown.

Why the Triceps Press Holds a Position in a Strength Line

The triceps are responsible for elbow extension and contribute to shoulder extension through the long head. They are active in every pressing movement and represent approximately two-thirds of the upper-arm muscle mass. A training programme built around bench pressing and overhead pressing without a dedicated elbow-extension exercise will leave the triceps undertrained relative to the pectorals and deltoids.

The GM47 addresses that imbalance. It isolates elbow extension through a fixed path, which means the resistance is applied directly to the triceps without requiring the shoulders or chest to stabilise the load. For a member running an upper-body split, this is the corrective exercise.

For a rehabilitation setting, the fixed path is the reason the machine is specified. The clinician can prescribe a specific load and a specific range without requiring the patient to control a free bar path. The movement can be performed unilaterally if the machine permits, which allows for symmetrical loading after injury — a standard protocol for addressing strength deficits between limbs.

The selectorised format also removes the plate-loading requirement. For a rehabilitation clinician, that means the patient can change the load independently without handling weight plates, and the load can be progressed in small increments that would be impossible with standard plate sizes.

1554 × 1068 × 1296 mm on the Training Floor

The assembled dimensions are 1554 × 1068 × 1296 mm. At 155.4 cm long, 106.8 cm wide, and 129.6 cm high, the GM47 occupies 1.66 square metres​ of floor space.

That footprint is 10.6 cm longer and 13.7 cm narrower than the 1242 × 1205 × 1296 mm GM44 and GM45 in the same range. The GM47 is therefore a longer and narrower machine, which changes how it can be placed against a wall or alongside other equipment.

The 106.8 cm width is the narrower dimension in the comparison, and that has a practical consequence. A narrower machine can be placed between two wider selectorised units without projecting into the walkway. In a row of plate-loaded or selectorised equipment, the GM47 will sit flush with machines that are 110–125 cm wide.

The 155.4 cm length requires more wall space than the GM44 and GM45. A leg of selectorised machines running along a wall must account for the full 155.4 cm per unit, plus the clearance at each end. This should be checked against the available wall length before the order is placed.

The 129.6 cm height clears standard ceiling heights without issue and matches the GM44 and GM45 exactly. A matched set of three machines — the GM44, GM45, and GM47 — will present a consistent top line along the wall, which is a material consideration for a facility planner. The visual consistency is not cosmetic: it indicates that the machines share a platform and will maintain consistent tolerances and finish across the order.

The working clearance should allow 0.60–0.90 metres​ on the stack side and 0.60–0.90 metres​ on the entry side. That gives a required zone of approximately 2.76–3.35 × 2.26–2.86 metres for safe operation.

206 kg and the Frame Stability

The net weight of 206 kg is 10 kg below the 216 kg GM44 and approximately 10 kg below the expected weight of the GM45 with its full stack. The difference is small, but it reflects the different loading systems: the GM44 is plate-loaded, while the GM47 carries its load in a fixed stack.

At 206 kg, the GM47 is stable under the loads typically used for this movement. A triceps press does not generate the same dynamic forces as a leg press or a squat rack. The user remains seated throughout the movement, which means there is no explosive phase and no impact transferred to the frame.

The trade-off is relocation. At 206 kg, the GM47 requires mechanical handling for any position change. A pallet truck or equipment dolly is the minimum requirement, and a two-person trained handling team should be used. The machine should be positioned during the initial fit-out rather than after the floor has been laid out around it.

For a distributor, the 206 kg figure determines the freight classification and the delivery requirement. It should be confirmed against the carton or crate dimensions and the gross weight before quotation, as the net weight alone does not account for packaging.

The Selectorised Stack and the Increment Question

The GM47 illustration shows a selectorised weight stack with a coloured top plate and a full stack enclosure. The specification sheet does not state the stack weight, the increment value, or the number of plates, and these are the three figures that determine whether the machine is suitable for the intended user base.

A standard commercial triceps-press stack ranges from 50 kg to 90 kg, with increment values of 2.5 kg, 5 kg, or 10 kg depending on the plate configuration. The increment value is the more important figure for a rehabilitation setting: a 10 kg jump is unusable for early-stage recovery, while a 2.5 kg increment allows measurable progression.

Buyers should request the following in writing:

• Total stack weight and the effective resistance at the pressing handles
• Increment value per plate
• Number of plates in the stack
• Whether the top plate is a half increment
• Whether the stack is fitted with a magnetic selector pin
• Whether the stack enclosure is included

The distinction between stack weight and effective resistance matters. A linkage system changes the mechanical advantage through the range of motion, so the weight selected on the stack is not necessarily the force applied to the handles. For a rehabilitation clinician prescribing a specific load, this difference must be known.

The stack enclosure is a safety item rather than a cosmetic one. It prevents a plate from being selected while the stack is in motion and protects users from pinch points. It should be confirmed as included before the order is placed.

Movement Mechanics and the Overload Position

The GM47 illustration shows the pressing handles positioned at approximately head height with the user seated underneath. This configuration places the elbows in a forward position relative to the torso, which places the long head of the triceps under stretch during the eccentric phase.

The long head originates on the infraglenoid tubercle of the scapula. When the arm is positioned overhead or forward of the torso, the long head is lengthened, and the resistance applied during elbow extension is greater in the stretched position. This is the mechanical basis for the machine’s specification.

A standing cable pushdown, by contrast, places the arms at the sides with the elbows fixed at approximately 90 degrees. The long head operates from a shorter position throughout the movement, and the loading profile is different. Neither movement replaces the other, and a complete upper-body programme should include both.

The GM47 also removes the grip variable. The handles are fixed to the linkage, which means the user cannot alter the wrist angle during the movement. For a member with wrist or elbow sensitivity, this is materially more comfortable than a straight bar or a rope attachment, both of which require the user to maintain a specific wrist position under load.

Adjustment System and the User-Height Range

The triceps-press movement requires the seat to position the shoulders and elbows correctly relative to the handles. If the seat is too low, the user will press upward rather than forward, which changes the resistance curve. If the seat is too high, the handles will contact the forearms rather than the hands.

The GM47 illustration shows a seat with a backrest, but does not show the adjustment mechanism. Buyers should request the adjustment range for the seat position and should confirm whether the backrest angle is adjustable.

A pop-pin adjustment is the commercial standard. It allows the user to make the change without tools and without assistance. A bolt-and-hole system requires the user to stand and manipulate a threaded fastener, which is slower and produces more service calls.

The user-height range should also be confirmed. A commercial triceps press should accommodate users from approximately 150 cm to 200 cm in height. The GM47 illustration shows a frame that appears to support this range, but the specification should be requested in writing.

The backrest angle is the other adjustment that affects the movement. A more reclined backrest changes the shoulder angle and alters the length-tension relationship of the long head. For a rehabilitation setting, a fixed backrest at a defined angle is preferable to an adjustable one, because it removes a variable from the exercise prescription.

Upholstery, Frame Finish and the Daily-Use Standard

The GM47 is shown with black upholstery and a grey frame with blue accents on the weight stack. The visual specification is not a technical detail: it determines whether the machine can be integrated into an existing colour scheme and whether the finish will survive daily use.

For commercial use, the frame should be finished in a two-coat powder system over shot-blasted steel. A single-coat or painted finish will chip at contact points within the first six months of operation. The welds at the main frame joints should be continuous and ground flush, and the frame tubing should be of a gauge appropriate to the rated load.

The upholstery should be high-density foam covered in a commercial-grade vinyl with double-stitched seams. The foam density determines whether the pad deforms under load, and the stitching determines how long the cover remains intact. Both should be confirmed by requesting material samples before a bulk order is placed.

The handles should be finished in a material that remains grippable under sweat. A polished chrome or plated handle becomes slippery during use and is the most common cause of user complaint on this machine type. Textured coating or knurled steel is the commercial standard.

GM47 Against the Category

The following table draws on specification sets published by manufacturers operating in the same commercial strength-equipment category. Where competing figures differ, the lower or more conservative value is shown so the comparison remains fair.

The comparison that matters is not the machine weight or the footprint. It is the combination of a seated selectorised configuration, a 206 kg frame, a 1.66 square metre footprint, and the long-head positioning — which places the GM47 in a commercial selectorised line rather than a plate-loaded strength facility.

Procurement and the Quotation Package

A distributor sourcing the GM47 should request a complete quotation package rather than a unit price. The minimum information required is:

• Full frame specification, including tubing dimensions and steel thickness
• Powder-coat specification and colour options
• Upholstery material, foam density, and colour options
• Weight-stack weight, increment value, and plate count
• Adjustment range for the seat and backrest
• Handle material and grip specification
• Movement path and effective resistance curve
• Rated load capacity
• Net, gross, and carton or crate dimensions
• Unit count per 20-foot and 40-foot container
• Spare-parts list and recommended stock levels
• Warranty terms, separated by frame, upholstery, and components
• OEM and private-label options, including logo application and colour matching
• Minimum order quantity and lead time

The last item is material. A facility equipping a new floor may require a matched set across multiple pieces, and the colour and finish must be consistent across the order. The grey frame and blue accents shown in the specification sheet should be confirmed as standard or optional before the order is placed.

Container Loading and Stock Economics

The GM47 at 206 kg net will produce a substantial carton or crate. The exact dimensions are not listed on the specification sheet and should be requested from the factory before production begins, along with a loading diagram and the exact unit count per container.

Based on the assembled dimensions, an indicative carton or crate would be approximately 1620–1720 mm in length, 1120–1220 mm in width, and 900–1100 mm in height. The gross weight will include the packaging material and should be confirmed in writing.

The commercial calculation is straightforward. A 20-foot container offers approximately 33 cubic metres of internal volume. At the indicative carton volume, the realised unit count will be modest, and the freight cost per unit will be higher than for cardiovascular equipment. For a distributor, this argues for consolidating strength-equipment orders across multiple SKUs rather than shipping single units.

Maintenance and the Failure Points

Selectorised equipment has more service items than plate-loaded equipment, and the maintenance schedule should be documented from the date of installation.

A workable schedule for the GM47:

• Daily:​ wipe the upholstery, the frame, the handles, and the weight stack. Sweat is corrosive and the largest single cause of premature frame and upholstery failure.
• Weekly:​ inspect the selector-pin engagement and confirm that the pin sits fully home in the plate. A partially engaged pin will damage the plate and create a drop hazard.
• Monthly:​ check the cable tension and inspect the cable for broken strands. A cable with more than two broken strands should be replaced immediately.
• Quarterly:​ lubricate the guide rods with a dry-film lubricant. Do not use oil-based products, which attract abrasive dust and accelerate wear on the stack plates.
• Every six months:​ inspect the linkage pivot points for play. Any lateral movement indicates bearing wear and should be addressed before the pivot housing is damaged.

The cable is the single component that determines whether the machine remains usable. A frayed cable changes the resistance curve and can fail under load. For a commercial facility, the recommended spare-parts stock should include one complete cable and one selector pin per machine.

Where the GM47 Belongs

The GM47 is suited to commercial gyms, rehabilitation centres, physiotherapy clinics, hotel fitness rooms, corporate wellness facilities, and fitness studios. It is a single-purpose machine, and it should be specified as part of an upper-body selectorised line rather than as a standalone purchase.

For a commercial gym, the GM47 provides the elbow-extension component that balances a pressing-focused upper-body area. For a rehabilitation centre, the selectorised stack allows load progression in small increments without plate handling. For a studio, it provides a low-coaching machine that members can operate without supervision.

The GM47 should not be specified as a replacement for a compound pressing exercise. It does not load the pectorals, the deltoids, or the scapular stabilisers, and it does not develop the strength required for bench-press or overhead-press performance. For those requirements, a different category of equipment is needed.

Frequently Asked Questions

What movement does the GM47 perform?

The GM47 is a seated triceps press. It isolates the triceps through elbow extension along a defined movement path. The configuration places the long head of the triceps under stretch during the eccentric phase, which produces a different loading profile from a standing cable pushdown.

What is the machine weight?

The specification lists 206 kg net. The gross weight and the carton or crate dimensions are not listed and should be requested in writing before quotation.

What are the assembled dimensions?

The assembled dimensions are 1554 × 1068 × 1296 mm, giving a footprint of 1.66 square metres. The height of 129.6 cm matches the GM44 and GM45 in the same range, which allows the three machines to present a consistent top line when placed in a row.

Is the GM47 selectorised or plate-loaded?

The GM47 is selectorised, with a weight stack and selector pin. The stack specification is not listed and should be confirmed in writing before ordering.

What is the stack weight?

The specification sheet does not state the stack weight, the increment value, or the plate count. Buyers should request these figures in writing. A standard commercial triceps-press stack ranges from 50 kg to 90 kg with increment values of 2.5 kg, 5 kg, or 10 kg.

Can the GM47 be used for rehabilitation?

Yes, within the correct parameters. The selectorised system allows load to be increased in small increments without plate handling, and the fixed movement path removes the requirement for the patient to control a bar path. The adjustment range and the backrest angle should be confirmed with the factory before use in a clinical setting.

How much clearance is required around the machine?

The machine footprint is 1.66 square metres, but the working zone should allow 0.60–0.90 metres on the stack side and 0.60–0.90 metres on the entry side. This gives a required zone of approximately 2.76–3.35 × 2.26–2.86 metres.

Does the stack weight equal the resistance felt at the handles?

Not necessarily. A linkage system changes the mechanical advantage through the range of motion, so the selected stack weight may not equal the force applied to the handles. Buyers should request the effective resistance curve before specifying the machine for rehabilitation use.

What warranty applies to the GM47?

The specification sheet does not state warranty terms. Buyers should request separate terms for the frame, the upholstery, and the components, as these carry different expected service lives.

Closing Note

The GM47 is a single-purpose machine, and that is its value. It performs one movement — seated elbow extension — and it performs it in a selectorised format that requires no plate handling and no supervision. At 1554 × 1068 × 1296 mm, it occupies 1.66 square metres and presents a consistent 129.6 cm top line with the GM44 and GM45 in the same range. At 206 kg, it remains stable under load without floor fixing.

Those facts define the specification. The machine is correctly placed in commercial gyms, rehabilitation centres, and studios. It is not a substitute for compound pressing, and the stack weight, increment value, and adjustment range must be confirmed before the order is placed.
