| 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 | ||||||||||||||
