Under Running Cranes and Monorails
Underhung overhead or bridge cranes are a good choice for factories and warehouse facilities that want to free floor space from obstructions and improve safety and productivity. Underhung cranes—sometimes referred to as under-running cranes—do not require supportive floor columns. This is because they typically ride on the lower flange of a runway beam suspended from the facility roof or rafters.
By optimizing end approaches, underhung overhead cranes make the most of facility space. That is, they allow the hoist to get closer to the end truck or end of the runway than is possible with a top-running crane. The underhung configuration also maximizes the bridge end approach, or how close the bridge girder can get to the wall or the end of the runway.

As their beams are suspended from building roofs, underhung overhead cranes are limited in lifting capacity—usually 10 tons or less. Before choosing an underhung crane you should have the structural strength of your facility’s roof evaluated. Supporting beams can be added to permit increased load capacity.
WeiHuaCrane sales professionals can help you explore all available crane options and choose the one best suited to your application and facility. They also can advise you on maintenance programs to keep your cranes operating at peak efficiency and reliability. Contact a sales representative today.

Under Running 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.
Under Running Cranes Type
Workstation cranes are usually small and light cranes, which can be divided into 4 types according to different frame structures: workstation bridge cranes, workstation gantry cranes, workstation jib cranes, and monorail cranes.

What is a Under Running Cranes?
A Under Running Cranes is a type of machine or equipment used in an industrial setting that allows you to lift and move heavy objects from one location to another in a precise manner.
Workstation Cranes consist of two parallel rails that rest on longitudinal I-beams and are contacted to opposite steel columns by brackets. The hoist, the lifting part of the electric winch, travels along the bridge.
Commonly used in various manufacturing companies and factories, the following are the applications of Under Running Cranes:
