This bridge crane system is a customized design for a low workshop which requires a high lifting height, based on international design standard, such as FEM, DIN, ISO. This crane is of the following advanced features:
(1) The electric hoist is of super-low headroom (Top & side running on main girder); trolley is of compact structure;
(2) The main girder & end carriages are of Europe style—strong rigidity, light weight, and pretty looks, etc.
(3) Crane and trolley are equipped with Taiwan style geared motors, which are of advanced features, such as small size, low noise, power-saved, long work life, etc.
1) high reliability, safety, free maintenance rate;
a) work duty: FEM2M, M5
b) Protection class: IP55
c) Insulation class: F
d) continuing rate: 60% ( for the high class motor)
e) Cooling rate: 30% than normal crane
f) Over temperature protection: 170℃
2) compact design, small size, low dead weight, low headroom
3) Low noise
4) Investment-saved---the workshop’s civil work cost, due to crane’s light dead weight and low wheel pressure.
5) Power-saved. The total motor power is much lower than normal design.
Euro-style Main Girder:
1. Main girder uses bias-rail box type structure, with optimized design and light dead weight.
2. Steel material. Q235B, or, Q345B.
3. The cover and web plate should get surface rust removal by roller-way conveyor blasting machine before welding; this blasting machine can perform blanking, sandblasting, painting and drying, after that they get to Sa2 level.
4. The welding work of main girder should be performed on work platform (welding assembly unit). In order to avoid distortion of main beam, we adopts U-shaped welding assembly unit to assure that vertical deflection degree between the top cover plate and joint edge of stiffened plate and web plate is no more than H/200, and also effectively reduce the partial wave of web plate.
Euro-style End carriage:
1. Material use Q235B, or Q345B.
2. It is made of rectangular steel-pipe or steel plate by welding, the finished end carriage get 1-time positioning process on numeral control machine in order to ensure dimension accuracy and fit tolerance.
3. Each end carriage is supplied with wheels with double-wheel rim, buffer and anti-derailing protection device.
( End carriages with SEW style geared motors)
