Mobile Overhead Cranes

Mobile Overhead Cranes Components

There are mainly bridges, crane walking systems, hooks, hoists, trolleys, and electrical equipment.

bridge
It consists of the main beam, end beam, walking plate, column, test cage, cabin, and platform.

Main beam

Welded box-type double main beam;
The steel plate material is steel Fe37 or Fe52;
The main end beam is contacted by high-strength bolts;
The main beam can be an ordinary track beam or a non-track beam;

end beam

The end beams are welded by rectangular tubes or high-quality steel plates;
The main beam and the end beam are contacted by bolts;

Crane Travel System

The ground control adopts a soft start, with a small current, no axial swing, less motor, suitable for the frequent start, and good green energy-saving effect.
The cabin controls our ZDR series tapered winding rotor, three-phase asynchronous motor, or electromagnetic brake motor, with high mechanical strength, compact structure, and adjustable braking torque.
The motor starts smoothly and brakes safely.
The sky wheel, platform wheel, and brake wheel are processed by medium frequency induction quenching and power frequency quenching, and the hardness of the heat treatment is controlled by a Leeb hardness tester.

Hook – Use a hook attached to the crane to support the lifted load (can also be a grapple, electromagnet, etc.).

Hoists – A device that lifts and holds, raises or lowers a load using a wire rope or chain hoist or electric winch.

Trolley – consists of a motor, a reducer, and a trolley frame.
The trolley supports the hoist and moves horizontally along the crane bridge in order to position the hoist and hook before picking up or lowering the load.

electrical equipment
The safety contact wire has high conductivity, low pressure, and high set electric sliding speed.
The wire ropes in the electric box are neat and easy to maintain.
The power supply of the trolley is provided by the flat cable.
Smooth sliding and beautiful appearance.

protective device
The outdoor crane is equipped with a hoisting mechanism, an electrical control box, and a rainproof device.
Set the trolley travel interval device.

anti-collision device

Sound and light alarm device

operating device
Pendants, Remote Controls, Cabin Controls
Dedicated cabins for overhead cranes or capsule cabs with a wide field of vision and comfortable operation.
