Motor Housing : Aluminum alloy casting, features rigid structure and light weight. Totally enclosed construction, withstands harsh conditions such as chemical and electro-plating enviroments , etc.
Motor : The lifting motor and travelling motor are Vacuum painted, the insulation class is F.
Motor Break : The side magnetic break device makes instant break as soon as the electric power cut off, to make sure the safety loading.
Limit Switch : Up/Down Limit switch fitted as both top and botton ends, shuts off power automatically to prevent load chain from running out.
Contactor : High performance non-fuse circuit breakers allow frequent trouble.
Phase Error Relay : A specially designed electric board prevents motor from running at it reverse phased.
Load Chain : FEC Grade 80 case hardned alloy steel chain, endures harsh conditions such as rain, salt water and chemicals.
Load Hook : Hot forget high tensile steel, rigid and durable, 360° swvel, fitting with safety latch to assure safe lifting.
Push Button Pendant : Protection class IP65. Fully water-proof and insulated, offers light weight and durability.
Transformer : Power to Pendant control reduced to 24V,36V,or 48V low voltage for safer operation.
