Power supply systems

Power supply systems are one of the most important elements of a crane and hoist system. In power supply systems, in addition to the power supply (including three phases), control controls can also be made through power supply systems، Becomes.

In general, power supply systems are divided into two main parts:

1. Conductor Rail
2. Festoon Cable

Conductor Rail

It consists of a series of metal belts or rods made of steel, galvanized, copper or stainless steel depending on the application and the amount of amps, as well as a non-conductive strip that covers it from three sides as a cover. Electric busbars are usually installed under or inside the carrier beam and transmit power by brush. When the length of the hall (shed) is long, expansion parts should be used, which should also be used for longer distances with more feed.

Advantages of electric busbars:

1. No restrictions along the hall
2. Relatively low costs on standard models
3. Low maintenance
4. Can be used on monorail routes on curved axes
5. Possibility to feed several cranes in one route

Disadvantages of power busbars:

1. Possibility of connection and electric shock in electric parts
2. Not usable in explosion-proof environments

Festoon Cable

Flat cable system and C-rail in short distances (about 40 meters) perform the task of supplying electricity to the crane. In halls where there are two or more cranes, C-rails and cables can no longer be used and the power bus must be used.

But in any case, flat cable and C-rail are used for power supply. Performs the task of transferring electricity from the main electrical panel to the crane lift.

The flat cable and C-rail system The electrical connectors are installed parallel to the carrier beam or the main crane beam, and the pulleys travel along the C-section of the rail and hold the cable with it. Flat cable and C-rail systems are a solution for hazardous and explosion-proof environments.

Flat cable system and C rail:

1. High acceptability
2. Use in corrosive and explosion-proof environments
3. Use in all work environments (indoor, outdoor) with limited path length

Disadvantages of flat cable and C rail system:

1. Not usable on long distances
2. Unusable for multiple cranes in one track

To choose the right power system, it is necessary to know the following:

1. Crane type
2. path length
3. Number of cranes and supplies
4. Number of phases and additional items
5. work environment
6. Voltage system
7. Temperature and duty cycle
8. Environment type
