Detailed Product Description
300 ton Electric Gantry Crane With Double-Trolley For Construction Of Hull Section For Ship Building
Description:
The gantry cranes are used for a wide variety of steps in ship assembly operations and provide the lifting capacity
required throughout the enture production process. Our crane installations already ensure efficient load handling
when work is carried out on the metal segments. They also guarantee that loads are precisely positioned - such
as large fittings when hull sections are built. Our industrial drives are used to move doors and building segments
safely and reliably in shipyards.
Features:
1. Material: All compression structural part of crane’s components chosen material with fine quality and meet
regulation. The important material has quality guarantee and inspection report.
2. Welding: In view of important welding seam and stress is more than tension weld of 70% allowance stress,
conducting fault detection check and take out 5% weld length by ultrasonic test. Inspection report provided to user.
3. Structure: The gantry frame is mainly including main girders, flexible leg and rigid leg. The flexible and rigid leg
structure is specially designed for large span. So the crane keep balance and reduce swinging while traveling.
4. Trolley: Two trolleys with different height. The higher trolley is designed with bigger span than the shorter one.
So the room under the higher one is enough for another trolley’s motion. It enables slewing large metal segment.
5. Motor: Drive motor must use China Top Brand: Jiangte Motor. Manufacturer have good achievement used and
provided detailed and actual parameter prove that it is good performance product. Insulation class ≧ F; Protective
class ≧ IP54.
6. Electric system: Inverter from famous brand ABB can make lifting and traveling in any speed you want
specifically for your work.
7. Control panel: Because of big span and height, cabin with joystick panel is the most fitting choice.
8. Painting: All steel is treated by sand blasting before doing paintings. There are 3 layers of paintings. The bottom
layer is zinc painting to prevent from rusting. The color of top surface should be average.
9. Limit switch for safety: mechanical limit switch: overload limit, height limit, rail end stop limit for traveling. Electric
protection: short circuit protection, lose phase protection, low-voltage protection, power failure protection, over
current protection.
10. Lighting: Adequate lighting under girder for operation at night. With alarm warning while moving for site’s
clearance and people’s safety.
Applications:
Mainly used in shipyard with high lifting capacity for construction of hull section.
