35mm² Integrated Power and Control Conductive Rail hoist cable
Overview of BUSBAR
Integrated Power and Control Conductive Rail is the power supply device which can replace traditional cables. The Sliding Contact Line is the device that composed of Current Collector, Conductive Conduits which hold Conductive Rails, and relative components.
Slide Contact Line Advantages
* Safety: The conduit shell of sliding contact line is wind-proof, rain-proof and snow-proof. The use of the device is not affected by the wind and rain and other bad weather. Its good insulation performance ensures no harm to the maintenance personnel when they touch the contact conduits.
* Reliability: The contact arc and the series arc phenomenon are effectively controlled.
* Economy: Sliding contact line device can greatly reduce the loss of electric energy.The conductive conduits can be segmented replaced, no need to change the whole cable in the case of local damage.
* Convenience: Easy to assemble/dismantle, commissioning and repair.

Integrated Power and Control Conductive Rail System Current Collector and its Auxiliary Assembly.
The Current Collector, which is the moving part of Sliding Contact Line, is a set of Brushes running in the Conductive Conduits. It is driven by the Guide Device installed on the construction hoist and runs synchronously with the hoist. It transmits the current from the Conductive Conduits to the motors and control elements of construction hoist. The poles of the Collector Brushes correspond to the Conductive Rails.
I, Current Collector: The device imports the electric current by sliding on the Conductive Rails inside Conductive Shells, to supply the power to the moving electric appliances. It is composed of Conductive Carbon Brushes, Balance Brushes, wires and shell.
II, Junction Box & Guide Device Assembly: Indicating power current, pushing the Current Collector moving and moderately absorbing the drive error and impact.
III, Guide Device Fastener: it is the connecting piece of fastening the Guide Device to the main steel channel of hoist cage.
How to maintain the Slide Contact Line?
During using, the following components of Sliding Contact Line shall be checked regularly:
I. Check the Brushes wear of Current Collector. If the wear length exceeds normal range, replace them immediately.
II. Check if Conductive Rails and their joints are rusted or loose. Whether the Fasteners, Guide Device, etc are loose?
III. Check if the Conductive Conduits deform or bend.
IV. Remove dust on the Conduits. When cleaning, no excessive force to avoid damage of the Conduits.
V. Check the Conductive Carbon Brushes in the Collector. When the Brush worn to its extreme extension length out of the housing is less than 2mm, the Brush should be replaced by a new one immediately.
VI. Check the wear of the Collector Guide Wheels. The Guide Wheels must be able to ensure the correct position of the Brushes in Conduits. Excessive wear of Guide Wheels will cause Brush wear or lose power occasionally.
