Heavy loads are the order of the day for developers in crane and hoisting equipment. Cranes and hoisting equipment have to be designed for ever increasing load capacities and combine high operational safety with a long service life. For several decades, we have been supporting manufacturers in this task based on our heavy-duty plastic components.
Components made from our materials contribute to the performance and reliability of many types of cranes and hoisting equipment all over the world. Owing to their excellent heavy-duty properties, abrasion resistance and zero maintenance, they often replace steel components. Our plastic components significantly extend the servicelife of the cables, prevent stick-slip effects and in that way increase the efficiency of cranes and hoists.
Cranes are constantly subjected to high loads and have to be absolutely reliable even in demanding areas of application. In cooperation with our customers, we aim to increase performance and reliability, reduce maintenance times and optimise safety.
Sheaves made of Lamigamid® (PA 6G), manufactured in the moulding process, are used by developers and manufacturers in crane and hoisting technology worldwide. Because of their high mechanical load capacity, dimensional stability and abrasion resistance, our sheaves are suitable for very high cable pull forces and support the performance and operational safety of cranes and hoists.
Different materials are available for different requirements depending on the application, for example for use at temperatures from -40°C to +60°C and in explosion-proof areas (ATEX). Ourmanufacturing processes and mechanical post-processing also enable us to manufacture special format castings. Our sheaves have an outer diameter of up to 3,090mm - world record!

Where cranes are used, cables have an important function. Pulleys made of Lamigamid® 310 (PA 6G) are safe, light and cable-friendly. In this way, they contribute to a high operational safety and reliability and extended maintenance intervals. The material combines high stability and wear resistance with weather resistance and impact strength. On request, we can supply Lamigamid ® 310 pulleys with pre-assembled, specially selected bearings.

Telescopic cranes and truck-mounted cranes have to be secure and stable. Plastic support plates are used for this purpose. Support plates made of Lamigamid® are light and stable and have a low impact on the ground surface. Even at high impact loads, the plastic plates remain dimensionally stable. Support plates made of Lamigamid® are used at support pressures of 250kn – 1500kn. Heavy-duty support plates are made of Lamigamid® 300 (PA 6G), Lamigamid® 310 (PA 6G) or Lamigamid® 400 (PA 6G).
We supply support plates complete with assembly material according to your requirements – both for permanently installed and removable versions.

Sliding and pushing movements occur in various places in cranes and hoisting equipment. The self-lubricating properties and high wear resistance of the sliding elements such as glide strips, glide sheets and sliding guides made of Lamigamid® support this process and prevent stick-slip effects.
