Third Rail Collectors

Brecknell Willis offer complete solutions for low level current collectors which are based on complete systems know-how, engineering expertise and extensive experience.

Advantages

Higher traction efficiency

Reduced maintenance

Reduced arc damage at the working interface

Maximum life of wearing components on both sides of the working interface (conductor rail and shoe)

Reduced electrical interference to auxiliary signalling and communications equipment.

Selection of the right shoegear/rail combination plays an important part in the achievement of good current collection. In general, the minimum head mass, effective dynamic mass and friction to assure optimum performance in all applications:-

Retraction

It is often a requirement to be able to retract the collector clear of conductor rails, to allow emergency isolation or through running into an area of overhead power supplies. Systems may be mechanical (by rope or lever), electrical, pneumatic or hydraulic and there are many design options available.
