Heavy Duty Positioners Built for the Biggest Jobs

With up to 150,000 pounds of lifting power and 1.5 million inch-pounds of torque, the ALM Heavy Duty (HD) Positioners line brings unmatched performance and increased throughput to heavy fabrication.

These intelligent, high-capacity positioners are engineered for some of the most demanding industries, like mining, railcar assembly, shipbuilding and more. They deliver powerful torque and lift strength, all in a compact footprint that maximizes shop floor efficiency.

Lifting Beyond the Standard

The HD line is purpose-built from the ground up for large-scale fabrication and engineered specifically for large and heavy weldments. While our standard positioners max out at 55,000 pounds, the HD series starts at 75,000 and scales up to 150,000 pounds, delivering a significant leap in both lifting power and rotational strength, with torque capabilities reaching up to 1.5 million inch-pounds.

“The key difference is lifting capacity and rotational torque,” says Rob Doneth, Process Engineer at ALM Positioners. “A regular positioner can handle something like a combine frame or cab, but the HD line is built to lift and rotate much larger parts, like ship sections, train cars, large crane frames or mining truck bodies. It’s designed for those massive, heavy-duty applications that demand serious strength.”

In addition to power, the HD line offers distinct advantages in design and performance. Despite the high capacity, these positioners maintain a compact footprint, saving valuable floor space. Plus, the HD models feature faster tilt, lift and rotation speeds, helping your team work more efficiently without sacrificing control or safety.

With 10 models available, including head and tailstocks, linear rail systems and three-axis sky hooks, we work with you to select the ideal configuration for your specific application. Every HD positioner is engineered for smarter control, higher capacity and a custom fit to meet your toughest fabrication challenges.

L24 Control Platform: Smarter Automation at your Fingertips

The control system is often the key to smooth, precise welding positioner operation. That’s why every ALM Heavy Duty positioner includes the advanced L24 Control Platform, which lets operators preprogram complex workflows and move to exact positions at the push of a button, reducing manual input, errors and training time while improving accuracy and consistency.

“The L24 control system is a powerful part of what makes the HD line so effective,” said Colten Brunenn, Technical Sales Engineer at ALM Positioners. “It comes standard and gives operators the ability to preprogram precise movements, automate repetitive steps and streamline complex workflows, all while keeping efficiency, safety and accuracy at the forefront.”

Designed for seamless integration with robotics, machinery and factory systems, the L24 Control Platform automates repetitive tasks to streamline workflows. By handling routine operations with precision, it frees skilled operators to concentrate on complex, high-value work, enhancing both productivity and safety across even the most demanding applications.

Completely Customized Solutions

Every HD positioner is ready for what’s next, including integration with VIKI OS, our Voice-Initiated Kinetic Intelligence Operating System. Operators can command the positioner hands-free using simple prompts from a helmet-integrated mic, streamlining workflows and enhancing safety.
Want to boost throughput even more? Pair your positioner with a collaborative robot (COBOT). This powerful combo allows welders to work alongside the robot or hand off repetitive tasks, doubling productivity while maximizing skilled labor.

Need even heavier-duty solutions? We offer custom builds beyond our 160,000-pound models.
