Reliable Overhead Crane Supplier in Indonesia

An overhead crane is a piece of equipment used for lifting and moving heavy objects, typically in industry and logistics. Its shape is similar to a bridge, with both ends sitting on tall cement columns or metal supports. It is placed horizontally over workshops, warehouses and stockyards, and can run longitudinally along the tracks laid on the elevated structures on both sides. There are many types of overhead cranes, including single-girder overhead cranes, double-girder overhead cranes, grab overhead cranes, etc.

The operation of overhead cranes requires professional operators and strict compliance with safe operating procedures. During use, attention should be paid to maintaining the stability and reliability of the crane to avoid problems such as tilting and overturning. At the same time, attention should be paid to protecting the crane’s electrical equipment to avoid problems such as short circuits and overloads.

Overhead Travelling Crane Parts :

1. Hoist & Trolley

In the single girder hoist (monorail hoist), the trolley wheels at the top of the hoist run on the bottom flange of the girder. It can be moved left and right along the girder or we called it crossing. Whereas in the double girder hoist, the trolley is paired with a rail at the top of the girder whose width is adjusted to the width of the flange on the trolley wheel. To drive the trolley, an electric motor that is adjusted to the maximum load, working-class and crane applications is used. There is a panel to control the work of the hoist.

2. Girder

Crane girder is an important part of the crane, usually including single girder crane and double girder crane.

The main beam of a single-girder crane generally adopts an I-shaped or box-shaped structure and is supported on tall cement columns or metal brackets at both ends through beams and columns. It has the advantages of short span, low consumption of construction materials, and low cost. It is suitable for occasions with small span, relatively light lifting weight, and relatively small construction site space.

The main girder of the double-girder crane adopts a double-girder design, which has a larger span and better overall stability. It is suitable for occasions with large span, large lifting capacity and large construction site space, and can meet the lifting needs of different occasions.

Structurally, single-girder cranes are relatively simple, light in weight, and relatively simple in installation, daily maintenance, disassembly and assembly, etc. The double-girder crane has a relatively complex structure, a large dead weight, and relatively complicated installation and daily maintenance.

In addition, double-girder bridge cranes have high technical content and high production costs. But it is relatively stable, has a large rated lifting capacity and a high working level.

In general, the crane beam is an important part of the crane, and different types of cranes have different main beam structures and characteristics.

3. End Carriages

To make the crane move forward or backward (travelling) then at both ends of the girder end carriages are installed, consisting of wheels, boxes, as well as motors and gearboxes. The wheel diameter of the end carriages adjusted to the capacity of the crane, the width of the span, the travelling speed and the working class. The parts of the girder and end carriages can be connected in a side joint (the end of the girder facing outwards with the outside side of the end carriages facing inward) or top joint (the bottom of the girder with the top of the end carriages).

4. Runway Rail

Crane rails installed above the runway beam with a width which adjusted to the flange on the end carriages wheels, it can be a flat bar, square bar or in some applications we can also use “A Rail” profile. For the runway beam, we can use IWF or H Beam profile steel material and usually above the console in a building column-mounted along with the long travel.

5. Electrical, Panel and Control

For the electricity supply along the runway, we generally use a power conductor rail system that will distribute electric current through a trolley connector mounted on left or on right side of crane. Then to continue the electric current to the hoist, we used festoon / flat cable which is connected with push-button pendant control, fixed one or mobile pendant that can be pulled or moved by the operator along the girder. Bridge panel (crane control panel) completes the electrical to regulates and controls the crane system.

6. Additional Components :

• Limit switches are an additional safety to reduce the speed of the crane in the horizontal direction (crossing and traversing) and stop it before the hoist or end carriage touches the stopper at the end of the girder or runway.
• Buffers are installed at the ends of the end carriages to reduce the impact that occurs if the crane still moving at the end of the runway and touches the stopper.
• The anti-collision device is a sensor used if there is more than one crane in the same runway to maintain a minimum distance between cranes and to avoid collisions or contact with the other crane.
• The wireless remote control is used to facilitate the operator in operating the crane so he does not need to be always close to the crane being handled.
• Buzzer and alarm added as a warning sign to personnel who are in the operational area knowing that the crane is running.
• Operator’s cabin is a special cabinet attached to the construction of the crane which made for the operator to control the crane. The operator’s cabin usually equipped with an operator seat, lighting, air conditioning, and there is a joystick control.
