Permadur Load Positioners
Permadur Load Positioners are designed to give operators precise, repeatable control when lifting and positioning heavy tools, dies, and components. Installed between the hoist and the load, a load positioner acts as a hydraulic link that allows fine adjustments — enabling placement within thousandths of an inch without damaging tooling or equipment.
Unlike standard hoists, which lift but lack precision, Permadur Load Positioners allow operators to accurately align and position loads safely and efficiently. This makes them ideal for applications where accuracy, safety, and repeatability are critical.
How a Load Positioner Works
A Permadur Load Positioner mounts directly between the hoist and the load hook. Once the load is suspended, the positioner allows controlled movement to fine-tune the load's position without repeated hoist jogging or manual force. This simplifies alignment, reduces setup time, and protects valuable equipment.
Permadur Load Positioners require no external power, making them easy to integrate into existing lifting systems.

Problem / Cause / solution / benefit
Problem
In many industrial, manufacturing, and assembly facilities, aligning heavy machinery, tooling, dies, or large components with precision can be slow, difficult, and error-prone. Manual lifting and positioning — or crude hoists — often lead to misalignment, tooling damage, excessive adjustment time, and poor quality control. This can throttle production throughput, increase scrap rates, and drive up downtime during assembly or maintenance.
Cause
Because heavy loads often exceed safe or practical manual handling weight limits, operations rely on crude hoisting or manual repositioning. Traditional hoists may allow the load to be lifted, but they rarely provide the fine control needed to align tooling or components within tight tolerances. Without precise positioning equipment, operators must make multiple adjustments — risking tool or part damage, mis-fits, and operator fatigue — and this iterative re-alignment eats time and reduces production efficiency.
Solution
Permadur Load Positioners provide a hydraulic link between hoist and load, enabling operators to lift, lower, and precisely position heavy loads with repeatable control and within thousandths of an inch. These positioners offer up to 40,000 lb capacity, with stroke options from 3” to 12”, and versions available for lift-only or lift & lower functions. Because they maintain positioning accuracy (≤ 0.001”), they dramatically reduce the need for manual adjustments, eliminate guesswork during alignment, and lower the risk of damaging tooling or equipment.
Benefit
Using Permadur Load Positioners results in faster, safer, and more accurate assembly, alignment, and maintenance operations. Production throughput improves because components and tooling align correctly on the first try — reducing rework, scrap, and downtime. Equipment and tooling last longer due to fewer impacts or mis-alignments. Operational safety rises as heavy loads are handled with precision hydraulics instead of manual force, reducing strain on workers. Overall, businesses save time and money — with higher quality output, lower maintenance costs, and improved reliability across workflows.
