Overhead Crane power line system: crane busbar, crane cable or sliding wire?

As a professional overhead crane and gantry crane manufacturer, Dongqi Hoist and Crane provides customers around the world not only the quality overhead crane and gantry crane, but also the crane traveling rails and crane power line system to win the satisfaction of you to our crane services.

Crane power line system

How to select the crane power line system for you overhead crane or gantry crane? Mainly the overhead crane and gantry crane power line option depend on the working site condition. Take the gantry crane for example. There are two kinds of situations in general:

• When the gantry crane is installed outdoors, the crane power supplying system usually adopts the crane cables.
• When the gantry crane is installed inside the workshop, the sling wire and crane cables are, in such case, are both ok for power feeding.

In the following are some detailed applications of sliding wire and crane cables. Sliding wire are divided into two kinds:

• One is seamless sliding wire,
• The other is single pole sliding wire.

Seamless sliding wire

The seamless sliding wire doesn’t have joint, which is a whole line, widely used when the crane travelling length is within 100 m crane traveling length.

Application:

1. when the crane travelling length is within 100m crane traveling length.
2.  Seamless sliding wire is suitable for single girder crane, and just one crane conductor bar is needed for each one crane.

Limitation: this option is limited within 100 m crane traveling length.

Advantage: The seamless sliding wire enables your crane reach the better performance when the crane traveling length doesn’t exceed 100 m, The seamless sliding wire can save your cost.

Suggestion: With the crane travelling length within 100 m, the seamless sliding wire is your choice under common situations.

Single pole sliding wire

Seamless sliding wire

The single pole sling wire is connected by pieces of wire, and it feeds the power through four lines.

Application:

1. The single pole sling wire  is suitable for double girder crane, and it doesn’t have limitations for crane traveling length.
2. Single pole sliding wire is suitable for double girder crane, and one crane needs four current conductors.

Advantages: No limitation on crane travelling length.

Limitation: It needs 4 crane conductors for every each crane, which is little expensive.

Suggestion: Single pole sling wire is your good choice for Double girder crane and cranes with travelling length more than 100 meters.

Gantry crane power feeding system: Crane cables and cable drum

Gantry crane power line usually choose cables, which have to be matched with the cable drum, installed on the bottom of gantry crane leg. Generally, the crane cables have two types:

1. Round cable is feeding power for long traveling.
2. Flat cable is feeding power for traverse traveling.

Power line option:

Generally speaking, common power line is used in the temperature between -20-+40℃, if the working environment temperature beyond the range, for lower temperature, there is cold resistance power line or cable, while for higher temperature working environment, there is high temperature resistance power line or cable. Therefore, it is very important to inform the detailed working condition of the site.

4. Check the sliding wires make sure they are installed straightly.

Crane power line

As the core part during crane working, crane power line plays a lead role, once there is problems, crane will have trouble or stop working, which will affect the factory production, waste much time and money, in order to avoid any interrupts during production, learning some basic skills is very necessary for the operation people.
