1. Introduction
30t electric chain hoist
Shell: It is made of light aluminum alloy shell,light but hard.The cooling fin is specially designed to ensure quick heat dissipation with the rate up to 40% and continuous service.The integral enclosed structure is applicable to places like chemical plant and electroplate factory. Side magnetic braking device : The magnetic orce generator is the latest design which is featured for generating magnetic force .It allows instant brake as the electric power is cut off .Thus the braking safety while loading is guaranteed. Limit switch:The limit switch device is installde where the weight is lifted on and off to make the motor to stop automatically so as to prohibit the chains from exceeding for safety. Chain:The chain shall adopt the importde FEC80 ultra heat-treatable aluminum alloy chain.It can be safely used in poor environments such as rain, sea water and chemicals. Hook:It is hot forging with perfect strength that is hard to break.The operation safety of the lower hook is ensured by its 360 degrees rotation and safety tongue piece. Support frame:The loading support frame consists of two steel plates . Which is extremely sturdy. Transformer:24V/36V transformer device .This device is used to prohibit unexpectde accidents caused by electric leakage and guarantees the safe use while raining. Electromagnetic contactor:Electromagnetic contactor can be used safely under high frequency. Inverse phase sequence protecting device:It is the special electrical installation which controls the circuit not to work in case of wiring error in the power supply. Push button:Waterproof push bush button is applied .It is light and durable.
