BES Pantographs - On track and pulling your weight
BES Rail Pantographs
A range of pantographs with varying base frame and collection head configurations are manufactured. The BES pantograph is approved by TRF (Transnet Freight Rail) and PRASA.
Our pantographs can be fitted with an automatic drop device (ADD), which is specifically designed to reduce or prevent damage to the overhead line infrastructure, locomotive roof equipment and the pantograph itself during any impact (hook up).
Our locomotive pantograph design accommodates a 3 or 4 point mounting depending on the specific locomotive type and roof layout.

Technical Design & Support
The pantograph structure is designed to be aerodynamically efficient. A variety of approved collector heads to accommodate contact strips (copper or carbon) are available. BES Pantographs are designed to accommodate AC or DC current. The up and down movement is controlled by a pneumatic cylinder and springs.
Pantographs are tested and set to customer specifications. Critical spares and technical field support is available, ensuring product efficiency. We also refurbish damaged pantographs.
A range of pantograph and buss-bar roof insulators are also manufactured to specification.
