Outrigger float pads made from LiNNOTAM – efficient metal substitution

LiNNOTAM Outrigger float pads

Whether a mobile crane or truck crane, mobile concrete pump, knuckle boom crane, aerial work platform or earth drilling rig, wherever heavy loads need to be distributed over large surface areas, the construction machine industry uses special float pads. With the cast polyamide LiNNOTAMHiPERFORMANCE 612 Licharz offers an engineering plastic that can withstand the highest loads and can effectively replace conventional steel pads.

The lightweight contender and its advantages over steel pads

Float pads made of LiNNOTAMHiPERFORMANCE 612 are much easier to handle in use and installation because of their low weight – construction equipment can therefore be designed lighter and more economically. The excellent material elasticity enables stable deployment even where the ground is slightly uneven and offers good protection when used on delicate surfaces. One further advantage offered by plastic float pads is the significantly lower cost compared to metallic float pads. They are also completely recyclable and resistant to fuels and lubricants.

LiNNOTAMHiPERFORMANCE 612 – ideal substitute for conventional float pads

  • low weight
  • high shock and impact resistance
  • high load capacity
  • high corrosion resistance against chemicals, weather and oils and greases
  • high resilience and recoverability after deformation
  • can be produced in almost any size
  • maintenance free
  • long service life

Proven stability using FEM analysis

When substituting steel with engineering plastics the question of load capacity in demanding applications quite rightly comes up: For their float pads made from LiNNOTAMHiPERFORMANCE 612 Licharz prepares a computational and modular proof of the possible loading using an FEM analysis (Finite Element method). In comparison to steel pads the pads made of engineering plastic offer a high resilience and recoverability after deformation and therefore have a much longer service life.

Efficient production using near net shape casting

Licharz float pads are manufactured using near net shape casting. In this process the LiNNOTAM is cast in a suitable mould. This preforms the basic contour enabling the float pad to be produced in a simplified production process
