Model NR explosion-proof wire rope hoist is a new design hoist made in accordance with GB/T 3836.1-2010 and GB/T 3836.2-2010, which is gas explosion-proof and dust-proof explosion-proof (ExdIICT4Gb/tD A21 IP65 T130℃). Work Duty: M5, SWL: 30t.
The hoist motor is an explosion-proof variable frequency electromagnetic brake 3-phase asynchronous motor. The speed of the motor is smooth and impact-free, with large overload capacity and good strength. It is especially suitable for short-term or intermittent operation, frequent starting and braking hoists. Insulation class: F, protection class: IP65.
There is a spring-loaded electromagnetic safety brake installed in the motor, which is released when the power is off. The brake service life can work up to 1 million times.
The hoist reducer is with a fully enclosed hard tooth surface. The gear is carburized and quenched, the tooth surface hardness can reach 58-62HRC, large load capacity, less working noise. The reducer case cover has high strength and good performance. The reducer has a second brake interface, which is convenient for users.
