NR Explosion-Proof Hoist

The new design NR explosion-proof hoist is made strictly in accordance with GB/T 3836.1-2010 and GB/T 3836.2-2010, which can meet the requirement of gas explosion-proof and dust-proof explosion-proof (ExdIICT4Gb/tD A21 IP65 T130℃), and can achieve the working level of explosion-proof M5. The rated lifting capacity of the electric hoist can reach 30t. We also provide classic explosion-proof hoist.

The motor is an explosion-proof variable frequency electromagnetic brake three-phase asynchronous motor. The speed of the motor is smooth and impact-free, with large overload capacity and high mechanical strength. It is especially suitable for short-term or intermittent operation, frequent starting and braking equipment. The standard insulation class of the motor is F, and the protection class is IP65.

A spring-loaded electromagnetic safety brake is installed in the motor, which is released when the power is turned off. The brake can work up to 1 million times.

The reducer is with a fully enclosed hard tooth surface. The gear is carburized and quenched, the tooth surface hardness can reach 58-62HRC, the load capacity is high, and the working noise is low. The reducer case cover has high strength and good performance. The reducer has a second brake interface, which can meet user requirements to a greater extent.
