DEMAC motorised cable reel with torque motor, with a monospiral or random-winding drum. The part number is defined according to the cable, length to be reeled and machine movement.
Send the full code, quantity and a nameplate photograph if available. For a replacement, specify the cable, exit direction, mounting dimensions and travel speed.
With or without cable, 2D/3D drawings on request. Power, signal or data slip ring assembly to be defined; PROFIBUS/PROFINET contacts and transmission tests on request.
Stainless steel version: DEMAC builds this reel in stainless steel on request; the reference usually carries the /IV suffix. State it with the full reference and the operating environment: the stainless grade, the protection rating and the components concerned are to be confirmed in the quotation.
The two tables reproduce the capacities of the four-conductor configurations from the monospiral pages of the Motor catalogue. Full motor/gearbox codes depend, among other things, on speed: 20, 40, 60 or 80 m/min. They must be confirmed for the required configuration.
Table conditions: drum on mobile equipment, horizontal cable exit, maximum mounting height 2.5 m, no deflection, acceleration 0.2 m/s². Stated nominal voltage: 0.6/1 kV. Slip ring assembly current does not replace verification of the cable’s permissible current.

For 4x16 mm², the catalogue associates lengths of 30, 80, 115 and 170 m with the additional indications 34+3, 85+3, 122+3 and 178+3. Total length and allowances must be confirmed with the part number.
| Configuration | Principle and catalogue reference values |
|---|---|
| Monospiral | Winding in a single plane, limiting torsion; cable exposed to air. Indicative maximum length of approximately 250 m; wheel up to 3 000 mm. |
| Random winding | Natural distribution without a cable guide, for short or medium lengths. Indicative length of approximately 180 m. |
| Random-winding tables | Separate selection: maximum three layers, horizontal cable exit, maximum height 1.5 m, no deflection, acceleration 0.2 m/s². |
The 180 and 250 m reference values describe drum types; the capacity of a part number remains that in the table for its cable and installation conditions.
The high-slip induction motor is designed for continuous duty. The catalogue states a range of ±400 rpm at the motor and torque fluctuation of approximately 10 %. The spring-applied brake releases when energised.
Single-phase axial fan for M01 to M08; three-phase radial fan for M10 to M25. Thermal class H: stated temperature rise of 125 °C and maximum insulation temperature of 180 °C. Thermal sensors must be connected to the machine’s emergency system.
Slip ring assemblies are defined for the requirement: contacts from a few mA to 400 A and nominal voltage up to 0.6/1 kV in the catalogue’s general presentation. These values do not apply simultaneously to every part number.
| Example: T5S2.35/056.130.30/M03 | Interpretation |
|---|---|
| T5S2.35 | T5 right-angle gearbox; S = standard drilling (N = non-standard); 2 stages; ratio 35. |
| 056.130.30 | Monospiral drum: drum diameter 560 mm, wheel diameter 1 300 mm, width 30 mm. |
| M03 | 3 Nm torque motor. The catalogue states M01 = 1.2 Nm and M02 = 2 Nm. |
