1.special properties:
rare earth and nanometer strengthened engineering plastic is a kind of new engineering plastic successfully developed by our company in recent years.it is the optimum material as replacement for steel, copper and aluminum, etc.
all of our products made of the engineering plastic can directlyreplace metal material with no change to the original designing size, the properties of strength, stiffness and fatigue can meet to the requirements.
(1) light weight:reducing dead weight at the end of a boom, whick provides mobile cranes with greater stability and lifting capability.
(2) improved wire rope life:self- lubricating, hardness lower than steel rope.
(3) wear resistance:8.8 times of steel, 8.3 times of copper.
(4) improved the property of crane, little or non maintenance.
(5) corrosive resistance:non-corrosive benefits for sea use.

2.application:
wire rope sheave, roller, gear, shaft sleeves, supporting wheel, locating wheel, worm wheel, chain wheel, synchromesh band wheel, pulley, hopper sheave, walking wheel, maintenance free bearing, etc.
