Overhead Cranes

Overhead cranes are efficient and safe lifting equipment, also called overhead travelling crane or bridge crane. These cranes come in four basic configurations, including single girder, double girder, top running and underhung system. Overhead bridge cranes can be designed to handle a variety of materials or loads, widely applied in manufacturing, warehousing, chemical, metallurgy, and other industries.

With a wealth of experience in the material handling industry, our group can help you select and specify the most appropriate crane system to maximize your work efficiency and safety, and also at reasonable cost.

How Much Is An Overhead Crane?

Since overhead cranes are highly customized products, their prices vary widely.

Generally, the cost of overhead crane is determined by several factors: type of crane, load capacity, span, lifting height, building or structural requirements, transportation cost, etc.

For example, if you own a large manufacturing plant, you may need large double girder overhead cranes to get the job done quickly and efficiently, which will cost much more than a smaller business that needs smaller overhead cranes to fit inside of a warehouse.

FAQs

What Are The Parts of An Overhead Crane?

Overhead crane is mainly composed of bridge frame (main beam, end beam, trolley running track, etc.), hoist trolley, bridge running mechanism and electrical control system.

Take A Closer Look At The Various Parts of Overhead Cranes

1. Bridge Frame

The bridge is the main force-bearing component of the crane. The main girder and end beam are the main load-bearing parts, supplemented by trolley tracks, walking platforms, railings, ladders and other auxiliary metal structures.

Main beam – The main beam is a box-shaped structure. The main load-bearing material of the main beam is Q235-B, and the minimum plate thickness is not less than 6mm.

End beam – The end beam is a box-shaped structure, and the connection between the end beam and the main beam is a rigid connection. In order to facilitate transportation, the end beam is disconnected, which is connected by high-strength bolts at site.

Trolley track – The trolley track adopts the whole track with joints welded together to ensure that the trolley runs well.

Walkway railing – The tread of the bridge platform is made of non-slip patterned steel plate with a thickness of 3mm. Railings with a height of 1050mm are set on the passages of the bridge frame.

Cabin – The driver’s cab is the working place where the operator controls the crane, and it adopts a closed, toughened glass cab. In order to ensure a wide view of the operator, tempered glass is installed on the upper front, lower front side and rear wall of the cab. An alarm is also set up in the driver’s cabin to ensure the safe operation of the crane.

2. Hoist Trolley

Lifting mechanism – It is used to lift or lower the goods, which is the most important and basic mechanism in the crane, and its work quality directly affects the working performance of the whole crane. The lifting mechanism is generally composed of a driving device, a steel wire rope winding system, a fetching device and a safety protection device.

Trolley runningn mechanism – It is the power device that drives the hoist trolley. In order to improve the working efficiency of the crane, the speed is generally faster.

3. Bridge Running Mechanism

The four wheels of the bridge operating mechanism are used as the support of the crane, and two independent drive systems are used to drive the crane separately.

4. Electrical Control System

Power supply – The standard power supply of our overhead cranes is three-phase AC, the rated voltage is 380V, and the rated frequency is 50Hz. It can also be designed according to user requirements.

Electrical protection system – short circuit protection, loss of pressure protection, emergency power off switch, overload limiter, travel limit switch, zero position and interlock protection, phase failure, phase error, overvoltage, undervoltage protection, ground protection, etc.

How Do Overhead Cranes Work?

The working principle of the lifting mechanism: the electric motor rotates after being energized, the speed is changed by the reducer, and then the drum is driven by the coupling, and the lifting and lowering process of the hook is completed through the wire rope winding system.

The working principle of the trolley running mechanism: The motor drives the wheels through the vertical reducer, coupling and drive shaft fixed on the trolley frame.

The transmission type of the bridge running drive system: a motor drives a reducer through a gear coupling and a transmission shaft. The low-speed shaft of the reducer is connected to the wheel shaft with a coupling, and the driving wheel ratio is 1:2. When starting, the driving wheel does not slip, and when braking, it is stable and reliable.

How to Operate Overhead Cranes?

Cabin operation – All mechanisms are operated by the cam controller or master controller in the cab to control the operation of the hoist, trolley and bridge mechanisms. An emergency stop button is installed in the driver’s cab. Press this button to cut off the power supply of the whole crane in an emergency.

Pendant operation – Press the buttons on the handle to control the actions of the crane’s various mechanisms.

Remote control operation – The corresponding mechanism of the crane is controlled by the industrial remote control.

In addition, the overhead cranes can be equipped with two sets of operating devices, that is, pendant control + remote control or cab + remote control.

However, due to safety issues, the two operating modes can only be switched to use and cannot be used at the same time.

How to Install Overhead Cranes?

1. The installation of overhead cranes is performed according to the agreement signed by the buyer and the seller. We can provide installation services or guidance services, and the cost is negotiated and determined by the buyer and the seller.

2. Regardless of which party is responsible for the installation, the site must be equipped with a commander in chief and a safety officer. The rest of the installers can be determined according to the scale of the project. The installers must have an installation certificate.

3. After the crane is installed, perform the initial trial operation of the crane. Rectify and debug the non-conforming items to meet the requirements of crane use and relevant crane standards.
