According to GB3836.1-2000 and GB3836.2-2000 rules, motor and electrical equipment are explosion-proof. When the explosion-proof grade is ExdII CT4, traveling mechanism shall do spark-proof treatment. This explosion-proof electric hoist is designed with explosion-proof levels ExdII BT4 and ExdII CT4, which can be used on workshop fixed suspension rail, also can be used with LXB explosion-proof suspension single beam, LB explosion-proof electric single beam, and explosion-proof hoist double beam.
Hoisting weight: 1-32t
Working temperature: -25°C – 40°C
BCD/BMD explosion-proof electric hoist adapts to the environment in the factory that has explosion gas formed by inflammable gas, steam, and air of which explosion-proof is less than B or C and ignition group is more than T4(135°C) group.
Structural characteristics
1. The explosion-proof electric hoist is composed of several parts that can be disassembled separately. It is very convenient to use, maintain and repair, and can shorten the repair cycle.
2. The explosion-proof motor and explosion-proof control box are separate explosion-proof structures. The control buttons, limit switches, and explosion-proof lifting weight limiter all meet the corresponding explosion-proof requirements.
3. The parts are widely used and interchangeable.
4. The reducer adopts standard modular cylindrical gears, which is convenient for maintenance.
Factory inspection
1. Each explosion-proof hoist shall be inspected and tested after it is qualified (including special inspection and test items required by users) before it can leave the factory.
The ex-factory products should be accompanied by a product qualification certificate.
2. Check whether the explosion-proof electrical equipment selected by the explosion-proof hoist has an “explosion-proof certificate”. Check explosion-proof electrical appliances according to the explosion-proof hoist design drawings
The model, level and temperature group of the equipment, and check the correctness of its installation.
3. Check the records of the implementation of 6.3~6.5, 9.1, and 9.2.
4. The rest of the inspection content should be inspected in accordance with the inspection items of JB/T 5317 or JB/T 9008.2.
