explosion-proof wire rope electric hoist series

brief introduction：

hb series explosion-proof wire rope electric hoist

hb/s series full-speed explosion-proof wire rope electric hoist

●explosion-proof wire rope electric hoist series is certified by the national cqst explosion-proof, and can be used in the hazardous area zone 1 and zone 2 locations classified by gb3836.14.

●applicable to petroleum, chemical, military, power, marine and other industries in the production of explosive gas mixtures in accordance with gb3836.1 under the normal working environment: iia, iib, iic category, temperature group t1 ~ t4 group, dangerous goods warehouses and other places are installed on single girder bridges or suspended cranes. they can also be installed on overhead i-beams. they can be used as lifting equipment for hoisting heavy objects, or they can be directly mounted on fixed frames as heavy objects. lifting equipment.

●explosion-proof wire rope electric hoist according to the lifting speed and operating speed can be divided into single speed, double speed and full two speed three. according to the installation method can be divided into a type (fixed type, there are four different direction of the upper and lower fixed direction), d type (equipped with electric running car, suitable for i-beam or single beam crane supporting the use of) two types.

consultation

● compact structure, light weight, small size, easy operation;

●the design and manufacture of explosion-proof structure are perfectly combined with safety and functionality, compact structure, small size, light weight, easy operation and beautiful appearance;

● the explosion-proof tapered braking motor with large starting torque can be used for frequent direct starting in continuous work. the maximum torque is 2.4 to 3 times of the rated torque.

● the use of standard modular helical gear reducer, smooth transmission, low noise, long life, easy maintenance and assembly.

● the gear reducer adopts three-stage deceleration of helical gears. the gears and gear shafts are all forged using 40cr or 20crmnti steel. after heat treatment, they are all supported by rolling bearings. the shells are made of cast iron, with tight assembly and reliable dust protection.

● the running motor is a trolley type. the reduction gear is 40cr forged, and after quenched and tempered, it is installed in a closed gear box, all of which are supported by rolling bearings. the wall plate is made of steel plate, which ensures flexible operation, convenient use and long service life. according to the height of lifting, the structure is also different.

● the reel is made of cast iron or seamless steel pipe, splined with a reducer, and the other end is supported by rolling bearings at the front end of the conical motor. the drum shell is made of steel plate.

● the hook is made of 20 steel forging, and the thrust ball bearing is used to connect with the shell through the hook beam so that the hook can run freely.

● the torque of the motor is transmitted to the speed reducer through the claw-type elastic coupling. the coupling can absorb the load shock and achieve a smooth start.

● the electronic control system has protection or warning functions such as loss of pressure, interlock, overload, and overload alarm.
