PRODUCT DESCRIPTION
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.

Explosion Proof Wire Rope Hoist use environment
Explosion-proof electric wire rope hoist use environment: temperature -20℃ -+ 40℃; Below 1000m above sea level; Relative humidity 85% (20±5℃).
Its main body can be suspended on the I-beam track for straight or curved running, or installed on the fixed bracket, as the lifting of heavy objects.
The BCD-type explosion-proof electric hoist can be used according to different requirements, it is used with an LXB-type explosion-proof single-beam suspension crane or LB, LHB-type explosion-proof single, double beam bridge crane. It is a small lifting device that can be installed on all types of cranes such as gantry cranes, bridge cranes, boom cranes, and other specialized cranes for lifting all types of materials. With minor modifications, it can also be used as a winch.
Wire rope explosion-proof electric hoist is suitable for grade ExdⅡBT4 / CT4, temperature group T1&T4 combustible gas, steam, and air formed by explosive gas mixtures, such as gas stations, oil refineries, petrochemical, flour mills, bamboo plants, and other places. Open flames are strictly prohibited in these places, and the use of production equipment is also strict. It does not produce mechanical sparks during use to meet the needs of the industry.
Caution
① The wire rope surface of the explosion-proof electric hoist should ensure that there is no broken wire phenomenon, the lubrication and maintenance of the wire rope should be done. To reduce the friction between the wire rope and the rope guide, drum, etc.
② When the explosion-proof wire rope electric hoist works in an environment with more metal obstacles, in order to prevent the hook of the electric hoist from colliding with metal obstacles. At this time, it is necessary to mark the announcement mark on the side plate of the electric hoist hook pulley.
③ The exposed part of the explosion-proof wire rope electric hoist should take speed-limiting technical measures, and the running speed of the explosion-proof electric hoist on the track and the speed of the wire rope involved in the line with the drum cannot exceed 25 meters per second.
④ It should be ensured that the joint place of the explosion-proof wire rope hoist track is kept smooth and smooth to ensure that the running sports car will not be blocked and impacted.
⑤ If there are two or more explosion-proof wire rope electric hoists running at the same time on the running track, it is necessary to set a slow device to prevent collision. To strictly control the quality of the buffer device, choose non-metallic material, and the resistance of the buffer device surface cannot exceed ten.
⑥ Ensure that the operation of the explosion-proof hoist is good, stable, and reliable, and prevents the wheel from slipping.
⑦ The power cord should use a flexible cable power inducer.
⑧ When the explosion-proof electric hoist is working normally, the surface temperature does not exceed 110℃.
⑨ Suitable indoor temperature -25 ° C ~+40° C, special circumstances need to be used outdoors need to add protective devices.
⑩ Mechanical parts to take flameproof measures, in order to prevent the electric hoist running friction, impact of high-temperature sparks, and the relevant parts for treatment.
⑪ In order to prevent sparks, an appropriate amount of mechanical oil should be injected into the hoisting and running reducer. Reels, steel cables, hook pulley bearings, wheels, and lifting and running motors should also be greased.
