Working Class: A5
All motors of QB type explosion-proof overhead cranes which electrical explosion-proof performance
is in line with GB3836.2-2000 "for explosive gas atmospheres with explosion-proof electrical
equipment-Part 2: Flameproof "d". And the whole performance is in line with provisions of the
standards of explosion-proof bridge cranes JB/T5897-1991. And all of the explosion-proof products
pass the inspection conducted by the state explosion-proof product inspection organization and
get the explosion-proof certificate. The proof marks are Exd Ⅱ BT4 and Exd Ⅱ CT4.

This product is generally the ground controlling and also be cab operating according to user needs.
Working level: intermediate.
Working level: intermediate.
The limiting size is the lowest between the top of crab and the track of trolley, that is to say, it
reduces 20%-30% compared with traditional products. Which can reduce the capacity of workshop
20% efficiently. It has hard-tooth reducer, imported wire-rope, and trinity drive. It is equipped
with such protecting devices as alarm device to overloading, obliquely hanging, second protecting
equipment preventing hook clashing the top, protecting the current lacking of any phrase etc. The
electric appliance adjusts speed without contact or spark module, and fulfil converter function,
including mini-speed and double speed, which make travelling and lifting very steady. The
operating board (handle) adopts 12v safe voltage. The electric controlling can be used more
than 2 million times when the voltage is 380v+5~-10%.

Compact Design
The advanced design idea gives the crane light structure and excellent performance, at the same
time narrows the hook operation distance in the maximum, and improves the space utilization
rate effectively. So it can reduce your workshop investment costs and bring more investment
returns.

Smooth, Fast Loading
The standard configuration of the crane are the trolley and crane both having stepless frequency
conversion control system, with features of braked stably, accurate location, and reliable performance,
which make traveling steady, positioning quick, solving the problem of swing of goods.

Safe, Reliable, Using Free Maintenance Design
The crane used the best technology in the whole process shows its superiority, especially
in the frequent operations. The perfect braking system improves safety and reliability a lot, which
can be adjusted by itself with dustproof design, and it can be used more than 1 million times.
Hardening and polishing the tooth surface will make sure the crane operate without trouble.
