Explosion-proof Electric Wire Rope Hoist

Explosion Proof Wire Rope Hoist Introduction

The mechanical structure of the explosion-proof wire rope electric hoist is basically the same as that of the ordinary CD and MD electric hoist. Explosion-proof electric hoist, that is, on the basis of ordinary wire rope electric hoist, made of special non-spark material, the motor, electrical appliance, running wheel, rope guide, hook, and operation handle of the hoist are explosion-proof. And explosion-proof performance is safe and reliable, according to the different environments, it is divided into gas explosion-proof and dust explosion-proof.

The lifting weight is 0.5-16ton, the lifting height is 6m-18m, the lifting speed is 3/0.3-8/0.8m /min, the working level is M3, the applicable ambient temperature is -20℃ to 40℃, and the explosion-proof level is ExdⅡBT4 / CT4. It is suitable for places with explosive gas mixture formed by combustible gas, steam, and air of class ⅡA.ⅡB, class ⅡC, temperature group T1&T4.

At the same time, it can be suspended on the I-beam rail to run in a straight line as a lifting heavy object, it is a powerful tool to improve the working conditions of the explosion-proof environment and improve labor productivity, so as to become the necessary equipment for processing.

Explosion Proof Wire Rope Hoist Details

An explosion-proof electric wire rope hoist consists of an explosion-proof motor, drum, explosion-proof brake, buffer, hook block, explosion-proof rope guide, explosion-proof handling handle, explosion-proof limit device, etc.

(1) Fire stopper: The hoist can cut off the circuit in case of emergency and has a device to protect the stopper, it can prevent the hook from exceeding the rise limit position, and avoid rushing to the top and the wire rope being pulled off.

(2) Handle design: thickened high-quality plastic forged handle, good sealing, excellent explosion-proof performance, easy to use.

(3) Electric hoist sports car: strong restraint, smooth operation, efficient and convenient.

(4) Flameproof brake: the lifting mechanism should have two brakes. There is another safety brake on the drum, the safety brake does not use electricity (purely mechanical) and is not affected by electricity, when the first brake is working normally, the safety brake does not work, when the first brake fails or other parts are damaged, causing heavy objects to slide down, the safety brake braking immediately.

(5) Buffer: the selection of polyurethane buffer or JB/T 8110.2 requirements of rubber buffer, surface resistance is not greater than 109Q.

(6) The design of the reel and the hook pulley group, so that when the wire rope is wound into or around the reel, the Angle of the wire rope deviates from the spiral groove on both sides is not more than 2, and the anti-stripping rope reel is made of cast iron or seamless steel pipe. Using the flower key to transfer power, the drum shell is made of steel plate welding, extending the service life of the equipment.

(7) Wire rope: Select the type and specifications in GB 8918-2006, advanced alloy load chain, and have reliable lubrication, high strength, and high wear resistance. The safety factor of the wire rope is not less than 4 when the working level of the lifting mechanism is M3; when the working level of the lifting mechanism is M4, it is not less than 4.5.

(8) Hook group: When the explosion-proof level is IIC, the fully forged hook enables the hook to take measures to prevent dangerous sparks caused by impact or friction.

(9) Overload protection devices can be provided upon request. Contact us for more details.
