Spring Cable Reels BEF
A BEF type spring cable reel consists of the following components:
– Cable drum
– Spring motor
– Slip ring assembly
– Mounting flange
– Various optional accessories
The cable drum is based on a heavy gauge sheet metal design. The drum body is epoxy coated for corrosion protection and the flanges are galvanised. The flanges are bolted to the drum body and the inside is exclusively used for the springs. It is mounted on both sides with lifetime lubricat ed ball bearings.
The spring motor consists of individually encapsulated springs made of special spring steel using the latest in steel making and spring technology. This guarantees long service-life (approx. 50,000 stress cycles or 100,000 move ments). The fully encapsulated springs provide a safe handling and replacement.
Slip Ring Assembly:
The slip ring is needed to transfer electric power and control signals from the fixed supply to the rotating reel. The reference voltage and the operating voltage are 415 VAC to 660 VAC, respectively; and the current carrying capacity ranges from 50 mA to 150 A nominal at +30?C. Multilayer coated sliprings in combination with silver collector shoes for data transmission are available upon request. Slip ring assemblies are designed for insulation group C and are all rated at 100% duty cycle. The slip ring housing made of impactresistant plastic has a dust and moisture protection grade of IP65. Slip ring types 16 and 19, in galvanized sheet metal housing, have a dust and moisture protection grade of IP55.
Cable reels are supplied with easy installation mounting flange. Special requirements or modified adaptations such as back stops, fixed or swivel guide arms with cable roller guides are available.
