Details of the best service gantry crane
This crane mainly consists of strong bridge beams,trolley-travelling mechanism,crab and electric appliances,and could be
classified into several working duties,e.g. A5,A6,A7,according to the
working frequency and pure working time.
Design and construction rules
All the standards required for the crane is according to China
Primer and finishing paint
Color:according to your requirements
Average thickness:about 100microns
Remote control, pendent line with push button , cabin control
(1) Mechanical parts configuration, good reliability: high-end product selection of domestic famous brand, parts, long life, low failure rate. Electrical components using Siemens, ABB, Schneider and other international well-known brand products, long service life, low failure rate.
(2)winding drum:Give priority to the adoption of Q345 high strength sheet roll welding, reducing weight also avoids the defect of cast steel drum drum.
(3)Motor: the domestic first-class production factory in the metallurgy and lifting the special variable frequency speed control of three-phase asynchronous motor. Motor attached over speed switch, encoder and other protective devices.
(4)Brake: main hoisting mechanism adopts hydraulic brake, the brake with brake torque, small volume, convenient adjustment, manual brake release device. And release the brake signal, signal based accurate speed control.
(5)Coupling: Plum elastic coupling, with damping, buffering, good performance, with large axial, radial and angular compensation ability, no need of lubrication, maintenance workload is small, light weight, go to the inertia is small, suitable for high-speed applications.
(6) Hoist reducer: hoist reducer of hard-toothed surface reducer, the anti-leakage technology reasonably, can ensure non-leakage reducer. Main hoist reducer is my company specializing in the design, manufactured by the domestic first-class gear box factory, gear for high strength and high quality alloy steel, carburizing quenching hardness of tooth surface, is 58 ~ 62HRC, the precision is 7-6-6 level, reducer noise ≤ 80 dB
(7) Three a drive: the car run institutions used motor, reducer, brake three together as a driving device is applied, simple structure, convenient assembly and disassembly.
(8)Girder bridge: using partial rail box girder, using Q345 high strength hot rolled flat plate (non - rolled plate and Kaiping plate), thick panel structure, the bridge of the strength, stiffness, high safety, beautiful appearance and light; using the advanced finite element analysis software ANSYS analysis of strength and stiffness of the girder, ensure the girder is safe and reliable.
(9) Frequency converter and the PLC standard for ABB/AB/SIEMENS/ Schneider / Yaskawa famous imported brand products.
