Hydraulic welding positioner with motor-driven rotation and hydraulic tilt
SRH
ACM supplies the Akyapak SRH hydraulic welding positioner for fabricators welding pressure vessels, tank shells, structural assemblies, and pipe spools who need both rotation AND hydraulic tilt of the workpiece under the welder. Where the SRP focuses on rotation alone, the SRH adds full hydraulic positioning of height and orientation, letting operators bring the welding seam to the optimal angle and height while the workpiece stays securely clamped. The result is faster cycle times, cleaner welds, and reduced manual handling that would otherwise require a crane or forklift between weld passes. The SRH lineup spans loads from 500 kg up to 35,000 kg (about 1,100 to 77,000 lb, or 0.5 to 35 metric tons), with table diameters from 715 to 2,000 mm (about 28 to 79 inches). Seven standard models (SRH-500 through SRH-35000) cover the most common production envelopes, and larger custom builds are available on request. A PLC control panel with a digital speed indicator monitors rotation in real time, and a foot pedal is available for hands-free operation. The vertically adjustable body and dual-axis rotation cover both right and left workpiece movement, giving the operator full control over how the seam presents to the welder. Workpieces clamp directly to the rotation table via standard T-slot channels. Hydraulic tilt covers 0 to 115 degrees on the smaller SRH-500 through SRH-7000 models and 0 to 90 degrees on the heavier SRH-15000 through SRH-35000 models, with a mechanical angle indicator showing tilt position. A 500 A welding-earthing mechanism is standard. Operators control rotation via a 5 m (16 ft) corded remote, and a wireless remote is available as an option. The SRH is fixed to the floor on most installations for heavy-duty production. ACM helps you select the right SRH model based on workpiece weight, table size, and tilt-range requirements, and supports installation, training, and ongoing service from Cambridge, Ontario.

Conventional welding positioner with motor-driven rotation
SRP
ACM supplies the Akyapak SRP conventional welding positioner for fabricators welding workpieces of varying sizes who need precise rotation control without the cost or complexity of hydraulic tilt actuation. Where the SRH adds hydraulic tilt to the same positioning concept, the SRP focuses on rotation and T-slot clamping, ideal for fabrication tasks where the workpiece angle is set during fixturing rather than adjusted dynamically during the weld pass. The SRP family covers an unusually wide load range, from light-duty work at 150 kg up to heavy-duty fabrication at 40,000 kg (about 330 lb up to 88,200 lb, or 0.15 to 40 metric tons), with table diameters from 500 mm to 3,500 mm (about 20 to 138 inches). Operators can regulate rotation speed automatically or manually throughout the welding process, and a digital display on the control panel monitors rotation in real time so any deviation can be caught immediately. Workpieces clamp directly to the table via standard T-slot channels, holding the part securely during the full weld cycle. The SRP is ergonomically designed to reduce manual labour and improve operator safety, replacing the crane and forklift movements that slow down a non-automated cell. The SRP integrates with Akyapak column-boom welding systems and welding robots for fully co-ordinated welding cells where the positioner handles workpiece rotation and the column-boom or robot handles torch travel. Operators control rotation via a 5 m (16 ft) corded remote control. Typical applications include pressure vessel and tank welding, cylindrical assembly welding, and any fabrication where consistent rotation under the welder reduces dependence on cranes and forklifts. ACM helps you size the SRP to your typical workpiece weight and table requirement and supports installation, training, and ongoing service from Cambridge, Ontario.

Compact H-beam welding machine with integrated straightening
HBW
ACM supplies the Akyapak HBW H-beam welding machine for fabricators producing custom-sized structural H-beams in volume. The HBW is the most compact and space-saving H-beam welder on the market, making it a strong fit for shops that want full automation without dedicating a long line. Plate parts are centred in the inlet conveyor groups, then welded together to produce H-beams across a wide range of flange widths, web heights, and material thicknesses. The HBW includes integrated beam straightening, and can be configured with single or double (tandem) welding torches when throughput demands it. A robust structural hull and meticulously developed columns deliver durability under sustained production loads, while a sprocket-driven feeding system, encoder-controlled by a PLC, gives precise speed adjustment for repeatable results. Motor-driven guide rollers centre both the web and the bottom flange with hydraulic alignment for high-precision welds. ACM helps configure the HBW to your typical beam sizes and backs the install with full commissioning, operator training, and ongoing service from our Cambridge, Ontario base.
