European type low headroom bridge crane have such design concepts as small dimension, light dead weight. Compared with traditional cranes, the limiting distance is minimum from hook to wall, and headroom is the lowest, which makes cranes work more close to the front, and lifting height more higher that increases effective working space of workplace.
Capacity:1ton-20ton
Span:6m-31.5m
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℃
Technological Highlights of Low Headroom Bridge Crane
1) Main beam use bias-rail box type structure, with optimized design and light self-weight.
2) The welding of main beam should be performed on working platform. In order to avoid distortion of main beam, our company adopts U-shaped main beam assembly machine with hydraulic forming which has won national patent ensuring that vertical deflection degree between joint edge of stiffened and web plate and upper cover cover should not more than H/200, and also efficiently reduce the partial wave of web plate.
3) Layout repair walkway on the drive sides of crane along the direction of main beam.
2. End beams
1) Material of end beam uses Q345B steel.
2) End beam is made of rectangular steel pipe or steel plate by welding, the finished end beam get once positioning processed on numeral control machine in order to ensure dimension accuracy and fit tolerance.
3) Each end beam is supplied with wheels with double wheels with double wheel rim, buffer and anti derailing protection device.
3. Connection of main beam and end beams
Connect main beam with end beam through bolts with end beam through bolts with high strength ensuring precision and smooth running of crane.
4. Conductive frame of crane and trolley
Conductive frame employs modular design and which consists of U-shaped bolt, connecting plate and rectangle pipes, the length and height can be arbitrarily regulated as well as easy installation.
It has complete equipments including main isolation switch, emergency disconnect switch, protection for short circuit, pressure loss, zero position , excitation loss, over current and over speed, which sufficiently implements conception of safety first.
Low clearance and small size.
Light deadweight.
More efficient workplace.
Adopt famous brand structure, Siemens motor, Schneider Electric, French wire rope, etc.
Double lifting speed, variable frequency running speed.
The above technical lights are all low headroom bridge cranes. They are also what convince our customers to choose our crane products as their workshop or industrial lifting equipment.
