An electromagnetic hanging beam overhead crane is an essential piece of engineering equipment in many different industries. It is designed to provide a safe and efficient way to move large and heavy items from one location to another. This type of crane is usually referred to as an EHBOC (electromagnetic hanging beam overhead crane).
Electromagnetic hanging beam overhead crane mainly consists of bridge, crane traveling mechanism, trolley, electric equipment and electromagnet. When used, the rotary part of the hanger of electromagnetic disk must be locked up with screws and no rotation is allowed.
The main component of an EHBOC is the electromagnetic suspension, which consists of two beams that are suspended above the ground. These beams are typically constructed with steel or aluminum and are fitted with electromagnets. The magnetic field created by the electromagnets allows the EHBOC to stay in place while still moving items along its track.
This type crane is heavy duty type with working duty is A6~A7, crane lifting capacity includes the dead weight of magnetic lifters.
Main Crane Parts Information
The material of steel plate adopts Q235B, if working temperature lower-20℃ or higher +40℃,adopts Q345 steel, all steel plates are under the process of rolling, shot blasting and rust removal, then paint primer.
 | Trolley | It is the lifting mechanism, lifting good up and down, travelling along the crane girder/ beam from the left side to the right side. It consist of motor, reducer, brake, drum, hook, coupling, hoist structure. We can separately supply electric crab/hoist for clients. |
 | Motor | The slip ring motors are used specially for crane, suitable for frequent starting, reversing & braking in accordance with ISO 9001:2000 ISO 14001:2004. Motors are totally enclosed in dust proof construction foot / flange mounted TESC / TEFC, Sq. cage motors with integrated safety brakes, insulation class F, IP54 protection for hoisting, CT & LT motions. |
 | Gear Box | The entire gear boxes are made of accurate hob cut helical / spur gears & pinions having hardness 250 to 350 BHN made from carbon alloy steel. All gears & pinions running on antifriction type ball/ roller bearings in totally enclosed oil bath giving constant splash lubrication. The helical/Spur gear designed for adequate strength and optimum wear resistance for smooth operation & long life. |
 | Brakes | Independent Hydraulic Brake make the crane much safe and easier to control |
 | Control box & cable | The surface of control box under anticorrosive treatment with reasonable layout and convenient maintenance. All the cables have color, number or with wire marking, which are easy to identify. |
 | Control mode | Operator cabin Wide vision, safety, comfortable Pendant control Remote control |
Safety Features Of Electromagnetic Hanging Beam Overhead Crane
Limit Switch
Safety limit switches for stoppers will be provided to prevent over traveling in all motions.
Anti collision device
When several units of crane travel on the same railway, the cranes can install the following devices:
Anti-collision device,Infrared non-contact and inductive type limit deviceSound and light alarm deviceWireless anti-collision deviceWeight overload protection device
When the crane overload works, it equipped with weight overload protection device, includes automatic stopping type lifting weight limiter and weight display device.
- Lifting limit switch and traveling limit switch
- Emergency stop system
- Electrical protectionThe main insulation switch, emergency stop switch, short circuit, Zero voltage protection, zero position protection, loss of field protection, Current overload protection, over speed protection, Phase sequence protection and adopted crane specially anti- vibration contactor etc. are all equipped, fully implement safety first concept.
- Interlock deviceIt sets interlock device for the cabin door and the other door from cabin into bridge structure, when the door is opened, the crane can not work.
