1.main girder

be welded of steel plates with honeycomb hole, connected by high-strength precision bolt.

there are sliding rail for trolley to travel upper the girder which is fixed on outrigger by high-tension precision bolt

2.outrigger

a. consist of rigid outrigger and flexible outrigger, all connection points are connected by high-tension bolt

b. the ladder is used by operator to enter into cab or arriving at winch

c.when the span>30m,there need a flexible leg aiming at reducing the lateral thrust the trolley has to the rail when the girder load objects

3.travelling mechanism

a.the driving gear box supplys power to realize the crane’s travelling.

b. what the difference between driving gear box and passive wheel box is that passive wheel box lacks transmission structure such as dynamo,

reducer and a pair of exposed gear

4. trolley with hoist

a.trolley frame welded of steel plate is the loading and travelling mechanism of trolley with hoisting

b.winch is the lifting mechanism of trolley..when it works, wire rope affects the pulley as rising and falling movement,

which makes suspended objects lifting and lowering

5. Cab

a. glass window through which one can watch overall working condition is installed in the front and two sides of the cab

b.Electric cabinet as a group of independent cabinet , fixed outside of cab is connected by control cable and linkage station which is set up in the cab

1,15 months warranty for whole machines.

2,Providing free quick-wear part.

3,Low charge for continue maintenance when warranty is expired.

4,Exclusive engineer support at any time.

5,We can provide free training to end-users.
