Detailed Description

The main structure include single-beam and double-beam. we can adjust the technical parameters to meet different clients’ requirements. ‘Keeping innovation and pursuing excellence’ are our critical concept. Warmly welcome every friend to our company. (1)Advantages 1. Honeycomb-girder (patented product) is first-made by Huazhong which enjoys a good fame in industry inside and outside 2. Light self-weight, large load, high wind-resistance and high rigidity, low deflection, so it is quite safe 3.Flexible legs, easy to transfer to another site 4. Reliable and unique pin connection, short-time installation 5. Lift objects easily by using winch 6. Imported and high-quality electronic components also ensure the safety of hand operation 7. Frequency-converter can be added to meet customers’ need (2) Introduction of honeycomb girder 1. Unique and new structure a. Triangle end face b. honeycomb hole in two sides inclined plate c. chord member on top and bottom d. connecting pin on junction 2. convenient to use and install 3. save materials 4. small windage area, high stiffness and transverse module, large bearing capacity (6)structure of the crane 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 consist of driving gear box and passive wheel box a. the driving gear box supplys power to realize the crane’s travellingb. 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 be made up of trolley frame, winch and pulley block 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 Warning: wire ropes need to be examined regularly and changed in time if there is a 10% broken wires, loosen wires and wearing down. 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 6. Electrical system a. lifting motor, crane travelling motor and hydraulic power motor are included. The whole electrical system is controlled by PLC. b. Two ways to operate the crane: cab operating and remote controlling. c. Electric components are imported from Schneider in Germany 7. Platform platform is installed in order to maintain the crane,the protective guard is added to protect the safety of servicemen. (7) After-sale service 1.We promise to provide brand-new and quality guaranteed products 2.we promise to provide practical solution to settle the problem the user encounters 3.One year warranty for whole machines. 4.Low charge for continue maintenance when warranty is expired. 5.Exclusive support engineer. 6.We can provide the free training to end-users.
