HIGH PERFORMANCE Cable Reeling Drums
Cable Reeling Drums
We are manufacturer and exporter of Cable Reeling Drums.
Spring Operated CRD
Standard reels are supplied for the cable fed in the clockwise direction, when viewed from the slipring side. The same can be provided for anticlockwise feed of cable also. These reels are extremely simple to mount, and can be mounted on the structure with the help of a supporting flange - If no suitable structure is available, then Unbalanced Vibrator Motor a bracket can be connected to the flange and this can be fixed to the floor or tray etc.
The springs used in these reels are manufactured from the highest quality materials and are of clock spring type. A wide range of characteristics can be obtained by assembling these springs singly or in series or in parallel.
All the power sliprings are designed for 600V AC operating voltage.
Spring operated cable reeling drums can also be supplied with geared rotary limit Switch arrangement.
ORTON have a complete range of motor driven torque controller cable reeling drums. The reels shown in this catalogue are direct reeling units where the cable compartment is mounted directly on the torque controller. For those applications where the length and weight of the cable is in excess of the design capability of the direct reeling units, we have the indirect driven torque controller reels. With these reels the torque controller unit powers the reel compartment through a suitably selected transmission system. These types of cable reels are a reliable, low cost solution for reeling long lengths of cable. These drums are available for a complete range of cable lengths from 30 to 500 meters, for voltage up to 11000 V. These spring operated cable reeling drums are easily installed, have an absolute minimum maintenance requirement and are virtually unaffected by extremes of temperature and environment. These types of spring cable reeling drums are available in 3 types viz monospiral, standard lay and random lay.
Torque controller type cable reel are driven by a substantially constant speed motive power unit. In its standard form, the reel is designed to be powered by a totally enclosed fan cooled electric motor. The most popular choice is for motors working form a 3 phase supply but single phase or DC motors may also be used provided they have performance characteristic as in accordance with the torque controller data.
The motive power unit drives the cable reel through an irreversible worm an wheel transmission which is totally enclosed and lubricated for life. The reduction ratio of this worm and wheel transmission is normally 50:1 and the rotational speed of the transmission out put spindle is adjusted by selection of the motive power speed. In all cases the selected rotational speed of this output spindle is in excess of that required for the cable reel.
The speed differential between the transmission output spindle and the cable reel is accommodated by the torque controller using a friction pad as the slipping interface.
The irreversible worm and wheel transmission and the stable torque characteristics of the torque controller permit successful cable reeling on the basis of energizing the motor for cable recovery. The benefits of energizing the reel motor for cable recovery only, are increased lining life and extended intervals between torque correction adjustments.
TC Payout Sensor Operation
The basic function of the payout sensor is to detect the rotation of the reel ensuring that the reel motor is energised during cable recovery and de-energised during cable payout. A limit switch is operated byaswivelingarm which is rotated by means of a cam fitted to the reel spindle. When the reel revolves in a payout condition the arm is moved until it opens the contacts in the limit switch de-energising the reel motor. In the reel-in condition the arm is rotated away from the limit switch making the contacts energising the reel motor.
Since the payout sensor cannot anticipate the direction of rotation of the reel under start conditions, the reel motor is always energised for 30 seconds by the incorporation of a timer in the control circuit which by passes the payout sensor contacts. This timer allows sufficient time for the sensor to detect whether the machine is moving towards the cable anchor position or away from it so ensuring that the reel motor is either energised or de-energised.
Moreover, the springs used in these reels are contrived from the highest quality materials and are of clock spring type.
These are available in three variations:Owing to their design, these drums help in reducing tensions in the reeled cable substantially as against other form of drive. Other, fruitful features includes, improving upon the lining life and they also extend intervals between torque correction adjustments.

In case of stall torque Motorised cable reeling drum the stall torque motor remains energized in both winding and unwinding operation of cable. In case you want to save power during long stoppages of machine, then a contractor and timer circuit can be installed in your panel. However, this is only an optional feature and is not a mandatory requirement. Since the stall torque motors are continuously rated, there will be no problem even in the motor remains continuously oh during both winding and unwinding direction.
These types of cable reeling drums are recommended for single layer winding of cables.
This arrangement can be used in two applications i.e., end and centre feed. In the end feed type, the drum is mounted on the moving machine and the reel recovers the cable laid on the ground. Here the machine travel is equal to the capacity of the reel. In the centre feed type, the machine travels on both sides of the fixed point, where a turnover anchor is installed. This arrangement provides travel equal to twice the capacity of the reel.
In this type also the reel is machine mounted and the biggest advantage of this type is that it does not have to pull the weight of the cable since, in this case the complete weight of the cable is felt at the fixed point.
In this type of arrangement. the cable is not laid on the ground but is suspended in the air due to the tension of the spring.
Here the reel is mounted on a fixed structure and has' to overcome the weight of the hose. The length of travel is equivalent to the capacity of the reel.
