Choose from these areas for electric hoist used in high temperature

environments

How to choose a high temperature environment to use yt electric hoist

• 1, there is a lifting mechanism configured to support a brake and a safety brake, electrical hoist in normal operation, the motor is braked by the brake cone, cone brake motor to support the brake, when the intermediate conical motor brake failure or When the transmission link failure, shaft mounted speed reducer DC electromagnetic brake for heavy braking, to avoid the risk of heavy stall. Meanwhile, brake motors and motor coordination cone between DC electromagnetic brake, an additional delay device in the control circuit, to avoid motor traffic jam occurs.

• 2, has an upper limit of a dual limit function. The first limit weight limit for the second stop of the conventional electric hoist, lower limit stopper off the fire.

• 3, electric hoist weight limit protection, electric hoist lifting from the weight of 90% of rated load limiter alarm, 105% of rated load lifting hoist power to stop working.

• 4, high temperature insulation protection, at the bottom of the reel housing design and installation of electric rope hoist machine heat shield to isolate the heat radiation of the molten metal.

• 5, lifting the motor and the motor running class F insulation class and built in lifting the motor windings overheat protection device.

• 6, special occasion rope configuration metallurgy high-temperature high-strength steel wire rope.• 7, using the remote control to control a priority, it can be centrally controlled.

The new installation, overhaul and after a year or left idle for the parking

hoist Checkpoints• The new installation, overhaul and after a year or left idle for more than two months double girder

overhead crane with electric hoist the parking must be checked prior to use by trained professional staff enabled, enabled only after acceptance, check the contents:

• 1, the main force component (suspended platform, suspended on hook) is permanently deformed, whether the weld cracks;

• 2, members tipping connections are lost or loose fasteners;• 3, the suspension mechanism is installed reliable and secure, with heavy compliance requirements;• 4, the rope is serious corrosion, whether loose shares, kink or severe broken wire, wire rope clamp

is correct and reliable;• 5, the electrical control system is flexible action, unlocking and locking function is normal:• 6, the safety lock action is flexible, unlocking and locking function is normal;• 7, up, down (including manual downhill) is running correctly, whether electromagnetic brake

clearance to meet the requirements;• 8, run the piece movement is normal, overhead cranes whether the operation is blocked

phenomenon is abnormal noise, the motor heat or smoke, burning smell produced;• 9, gear box and gear are required filling or replacement of oil.
