'''Motorized Cable Reels''' are used as power supplies for moving loads for automatic winding of flexible power and control cables and are accident prevention regulations. The drums can be made in a spiral or cylindrical winding. The trigger line is horizontal or vertical. | |||
==Features== | |||
*All bolted construction | |||
*Metal drum standard, PVC drum optional | |||
*Motor mounting at either end of reel | |||
*Chain and sprocket shroud is optional | |||
==Operation Princples== | |||
The Motorized Cable Reels uses the following drive systems: | |||
*Three-phase motor with compact drive unit | |||
*Three-phase motor with frequency inverter including constant and variable torque | |||
*Torque motor | |||
All drives work in the direction of cable travel. The unit uncoils the cable by extending (paying out) the cable from the reel body against the torque provided by the drive unit, which adjusts to the travel speed of the reel until the reel comes to a standstill. For safety, a brake avoids uncontrolled cable payout in case the drive loses power. | |||
==Applications== | |||
*Hose reels for air, liquids and gases | |||
*Tag line reels for handling steel ropes | |||
*Reels for control, signal and high frequency transmission cables | |||
*Offshore reels, including on ships or in the tropics | |||
