Application Examples

+

Support plates and support plate pads

Cranes and construction machines have to be secure and stable. Lamigamid® support plates are light, stable and have a low impact on the ground. Even at high impact loads, the plastic plates remain dimensionally stable. Support plates made of Lamigamid® are used at support pressures of 250kN to 1,500kN. Heavy-duty support plates are made of Lamigamid® 300, Lamigamid® 310 or Lamigamid® 400. We supply support plates complete with assembly material according to the customers’ requirements – both for permanently mounted and removable versions.

Door rollers

For many years, heavy-duty door rollers made of Lamigamid® materials (PA 6G) have been used in large (freight) lifts. All Lamigamid® materials have a high fatigue strength and good resilience. Their modulus of elasticity is significantly lower than that of steel or cast steel. The low modulus of elasticity has a positive effect on heavily stressed running wheels by reducing contact loads. Various plastics having different properties are available for heavy-duty door rollers BU1:Door rollers made of Lamigamid® available in many different diameters and with built-in bearings on request BU 2: Construction view with heavy-duty door rollers made of Lamigamid® in various diameters Properties: High fatigue strengthGood resilienceLow moduli of elasticity

Sliding elements for telescopic booms

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. + Slider for curved telescopic segments + Guide of the hydraulic cylinder in the telescopic boom + Slider in the construction machine + Slider with grease grooves Properties Heavy dutyLow moisture absorptionGood emergency operating properties

Support plates

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, Lamigamid® 310 or Lamigamid® 400. We supply support plates complete with assembly material according to your requirements – both for permanently installed and removable versions. + Removable support plate made of Lamigamid® 300 + Support plate made of Lamigamid® 300 with variable positioning + A Liebherr LRS 545 Reachstacker with a support plate made of Lamigamid® 300, © Liebherr Special features: Heavy dutyLighter than steel structuresShatter-proof, shock-resistant and impact-resistant

Castors

Castors -Castors made of our materials Sustamid® 6G and Lamigamid® machined within tight tolerances are subject to less wear than steel because of their excellent abrasion resistance and high mechanical strength and toughness, are low-maintenance and thus make for a very long servicelife. We would be happy to advise and support you in selecting materials, designing and performing stress computations.
