Explosion-proof electric hoist is based on the latest explosion-proof standard design and manufacture of small-sized lifting equipment, the flameproof is explosion-proof form. It has the advantages of light weight, small volume and large lifting capacity.
Motors and electrical equipment is explosion-proof, explosion-proof exposed parts of the use of special sparkless materials, explosion-proof performance is safe and reliable, when in charge of the plant have an explosive mixture, using this equipment can ensure the safety of staff and the workplace.
1. Explosion-proof electric hoist is made up of several independent detachable parts which are very convenient to use, maintain and repair
2. Used Separate explosion motor and control box. Control buttons, limit switches, explosion-proof weight limiters meet the corresponding explosion-proof requirements.
3. The parts are versatile and interchangeable, the reducer adopts standard module cylindrical gear for easy maintenance.
Explosion-proof electric hoist as the lifting system of the crane is suitable for classⅠ explosion-proof coal mine and applicable to class Ⅱexplosion-proof have ⅡA, Ⅱ B, Ⅱ C level, temperature classes T1 – T4 group of combustible gas or vapor and air form the sites with explosive air mixture. Working environment temperature is 25 ℃ to 40 ℃, suitable for indoor use. Protective devices are required when used outdoors.
The safety device are not only the electric protective devices or alarm bell but other equipments are necessary to guarantee the normal operation of crane and avoid the personal casualty and mechanical damage.Such as:
♦ Weight overload limiter
♦ Emergency stop system
♦ Crane travelling limit switch
♦ Voltage lower protection function
♦ Current overload protection system
♦ Top quality long time bearing polyurethane materials buffer
