Stall Torque Motor Operated Hose Reeling Drum
we are leading stall torque motor operated hose reeling drum , manufacturers, suppliers and exporters located in ambarnath midc dist thane, maharshtra india.
Torque Motor Operated Hose Reeling Drum suitable for handling lengths of Hose in excess of those which can be handled by a conventional spring operated types. The units are totally enclosed and weatherproof. The torque motors are capable of operating continuously in the stalled position or of being rotated against normal phase rotation.
In other words acting like a spring of infinite length. The motors have an integrally mounted electro-magnetic brake which is D.C. operated through a built in rectifier. Normal motor supply is 400/440 volts 3 phase, 50 Hz . The drive to the reel is by means of chains and sprockets, with single or double reduction accordingly to requirements.
