New Chinese explosion-proof bridge crane

product description
Bridge crane is a mechanical equipment that is placed horizontally above workshops, warehouses and open-air storage yards and is used to lift various objects. It is usually called a “crane” or “driving crane”. Ex-proof crane is the most widely used lifting machinery in the mechanical industry, metallurgical industry and chemical industry.

Factory sevencrane ex-proof crane wholesale are mainly used in dangerous and important places with flammable gases or flammable mixtures. Their basic structures are similar to ordinary bridge cranes, but explosion-proof measures are taken in mechanical parts such as motors and electrical parts and metal contact surfaces to ensure that To ensure the safety of use in explosion-proof environments; Nukelen’s new Chinese-style explosion-proof bridge cranes include explosion-proof electric suspension cranes, explosion-proof electric single-girder cranes, explosion-proof electric hoist bridge cranes, and are used with new Chinese-style explosion-proof electric hoists.

New Chinese style explosion-proof wire rope electric hoist
The new Chinese-style top choice for industrial ex-proof crane is a special industry electric hoist developed for explosive environments based on the NR wire rope electric hoist. The basic working level can reach M5 and meets JB/T 10222-2011 “Explosion-proof Electric Hoist”, GB3936.1-2010 “Explosive Environment Part 1: General Requirements for Equipment” and GB3836.2-2010 “Explosive Environment Part 2: Equipment Protected by Flameproof Enclosure “d”” national standard requirements.

The CE approved ex-proof crane for sale drive device equipped with the new Chinese-style explosion-proof bridge crane is a product independently developed by Nukelen for the new Chinese-style explosion-proof products. It is smaller in size and lighter in weight while meeting the requirements for use in explosion-proof environments. It is also used in electric hoists. The smaller lifting height enables the electric hoist to operate within a wider range. It can meet dual explosion-proof levels of gas explosion-proof and dust explosion-proof (ExdIICT4Gb/tD A21 IP65 T130℃), and can achieve the M5 working level status of explosion-proof hoist.

Explosion-proof three-in-one operation driver
The motor is a flameproof variable frequency electromagnetic brake three-phase asynchronous motor. The motor’s speed regulation is smooth and impact-free, and it has large overload capacity and high mechanical strength. It is especially suitable for equipment that operates for short periods of time or intermittently and frequently starts and brakes. The standard insulation grade of the motor is F, and the protection grade is IP65. The brake can safely brake up to 1 million times.

The reducer is a fully enclosed hard tooth surface type reducer. The gears have been carburized and quenched, and the tooth surface hardness can reach 58~62HRC, with high load-bearing capacity and low operating noise. The reducer box cover has high strength and good performance. The reducer has a second braking interface to meet user requirements to a greater extent.

New Chinese style explosion-proof electric hoist
1. The electric hoist adopts a lightweight design concept: simple structure, exquisite appearance, and easy operation.
2. The electric hoist structure adopts modular design: mass production, stable quality, good interchangeability, and easy disassembly and assembly.
3. The electric hoist has good operating status: it adopts variable frequency control, which can reduce the shaking of the product during lifting and improve the safety of lifting.
4. The european standard ex-proof crane suppliers is equipped with a variety of safety protection measures. Devices such as a second brake, overspeed protection, stall protection, and safety monitoring systems can be added as needed to improve the safety of lifting items.
