Brief introduction
Tower crane has a horizontal jib frame, a jib-trolley radius-changing mechanism and a hydraulic self-raising mechanism. It is original in design, reliable in operation and satisfactory in shape. Equipped with all necessary safety devices, these cranes show a good speed-control capacity, satisfactory operating stability and high work efficiency. Topkit tower crane is commonly used in ports and ships.Top kits tower crane can be rotated, but it can only be lifted in different lengths of the angle at which the pointed head is
raised. The lifting radius area is relatively small, but the lifting capacity is basically irrelevant to the position, and the lifting capacity is basically fixed.
Feature of tower crane
1.Suitable for all kinds of construction project and can work under all kinds of work condition.
2.It has high working speed, good speed-adjusting performance, steady operation and high efficiency.
3.The crane has complete set of safety devices, which can guarantee the safe and high efficient operation of the equipment.
4.Three-speed motor and mono-speed ratio decelerator are applied in the lifting structure, which enables heavy load low speed and light load high speed.
5.Planet gear decelerator is applied in the circumcise rating structure, together with moment-limiting hydraulic couple,
which can realize high load capacity, steady starting and reliable operation.
Safety features
Full set of safety protection equipment:weight limit,moment limit,height limit, and slewing limit,emergency brake, labor protective devices like rest platform and guardrail.
1.Weight limit: If the material is over the capacity, the crane will give a sharp warning for protection itself.
2.Moment limiter:Real-time monitoring and detection of crane working conditions, with its own diagnostic function, rapid dangerous status alarm and safety control.
3.Height limit:Control the lowest and highest extreme position of lifting hook.
4.Slewing limit: Control the extreme turns number of turn left and right.
5.Emergency brake: If the operation staff encounter some emergency situation, we could start the emergency brake system to protection the related treasure.
Advantage of Tower Crane
1.Robot automatic welding system;
2.Automatic impeller blasting and spraying assembly line;
3.CNC plasma cutting machine;
4.Precision machine tools;
5. France Schneider contactor;
6.Jiangte motor;
7.Equipped with complete set of safety devices
Control mechanism
Hoisting mechanism is driven by three-speed electromotor with high working speed and good speed-adjusting capability and high efficiency; Derrick mechanism using worm-wheel reducer can meet operating needs. Slewing mechanism that is driven by two-speed electromotor; Make operation more stable and reliable.
