State each drum's working-layer pull
Provide the maximum pull and holding load for line A and line B; identify whether both lines act at once.
- Line A and B force
- Simultaneous-use load case
- First and last working layer
TWO-DRUM / PROJECT CONFIGURATION / ELECTRIC WINCH
Double-Drum Electric Wire Rope Winch
Use two separate rope drums when a project needs two defined line routes in one engineered arrangement. Specify the load and usable travel for each line, whether they operate together or independently, and how stopping and holding must work. The drum layout and technical schedule are prepared around that operating sequence.

01
Single-unit enquiries welcome
Model, minimum order and supplied equipment are confirmed in the written quotation.
02
Drawing-led selection
Confirm rope route, working-layer pull, drum, brake, controls and foundation as one arrangement.
03
Clear delivery and support scope
Agree inspection, documents, packing, schedule, installation support and warranty before the order.
01 / SPECIFICATIONS
Specify both rope lines before selecting a double-drum winch.
A two-drum winch is defined by the relationship between its lines. The selected unit's rated pull, speed, rope capacity, diameter and brakes should appear per drum on one approved layout and technical schedule.
Compare the load path, rope movement and selected arrangement →
| Parameter | Selection requirement | What the drawing must resolve |
|---|---|---|
| Line A and line B rated pull | Specify separately in kN at the required working layers | Include the simultaneous-load case and any reeving losses. |
| Line speed | Specify separately for each drum (m/min) | State whether the lines may run independently or must move together. |
| Usable rope travel | Specify for each line (m) | Allow for dead wraps, sheaves and the planned operating range. |
| Rope diameter and construction | Select for each drum (mm) | Match rope, drum, sheaves, anchorage and required service. |
| Operating sequence | Linked or independent, as required | Define start, stop, hold and emergency behaviour in every operating state. |
| Brake and limits | Selected to the load path and duty | Include the condition where one line moves and the other holds. |
| Drum and base dimensions | Project general arrangement drawing | Confirm drum spacing, rope exits, base footprint and anchor forces. |
| Power and environment | Match site voltage, frequency and exposure | State installation location and the required control position. |
The approved technical schedule identifies a matched pull, speed, rope capacity and diameter for each drum. Combined duty and control logic are checked as a complete system.
What has to happen when one line stops?
Define whether the other line may continue, whether both lines must stop together, and how the load is held in every operating state. That decision affects drive and brake selection, controls, limits and acceptance testing.

02 / APPLICATIONS
Two rope paths for a defined handling sequence.
01
Two-point positioning
Control two attachment points on a long or irregular structure. Provide the load share and movement sequence at each point, including the consequences if one line stops first.
02
Construction and installation
Route two ropes around the worksite to pull or position an assembly. Give the anchor positions, sheaves, clearances and usable travel for each line.
03
Coordinated equipment handling
Where two lines must move as one operation, define permissible speed difference, stopping logic, operator view and how both loads are held.
Two drums do not automatically give synchronized motion or double the safe load. The complete system must be reviewed for the actual rope paths and duty. Compare electric hoists.
03 / CONFIGURATION
Make the winch match the work—not only the model code.
Line pull, rope travel, speed, stopping and site interfaces must work together. The chosen equipment and the installation plan should be reviewed as one package.
04 / QUOTATION SCOPE
Compare complete winch offers.
Two prices are only comparable when the rope package, controls, site interface, documents and delivery boundary are the same.
Winch and rope package
Specify the selected drum, motor, gearbox, brake, wire rope and base. Identify any sheaves, rope end fittings or guards supplied with the unit.
Define:Working-layer pull, speed, usable travel, duty and pulling or lifting service.
Controls and site interface
List the control cabinet, pendant or remote, limits, emergency stop, power connection, foundation and anchor responsibilities.
Define:Where the operator stands, how the load stops and who provides the installed rope path.
Delivery and acceptance
Agree drawings, inspection, export packing, freight, unloading, installation support and commissioning before production begins.
Define:Incoterm, destination, document scope, production programme and after-sales terms.
05 / ORDERING & DELIVERY
Approve the rope system before manufacture.
The project offer should connect the operating brief to an approved winch arrangement, production, inspection, packing and site handover. Dates and responsibilities are confirmed for the selected configuration.
Ask for a project document list
- Selected winch general arrangement and base/anchor drawing
- Per-line pull, speed and usable rope travel schedule
- Rope, reeving, brake and control description
- Electrical supply and control schematic
- Agreed factory inspection and test records
- Operating, maintenance and applicable destination documents
For a suspended-load duty, identify the applicable acceptance and conformity requirements before the equipment is selected.
- 01
Brief and technical selection
Agree the load path, drum-layer pull, rope travel, speed, brake duty and installation interfaces.
- 02
Drawing approval
Check the drum, controls, base, anchors, rope exits and document list against the site.
- 03
Build, inspect and dispatch
Confirm witness points, agreed tests, packing, dispatch and transport dimensions.
- 04
Install and hand over
Assign local labour, wiring, anchoring, rope installation, testing and operator instruction.
One-unit enquiries welcome
Minimum order and the scope of the supplied rope system are stated in the written quotation.
Documents for the selected unit
Tell us the destination and required standards; the offer lists applicable documents, inspection and agreed test records.
A dated project schedule
Drawing approval, production, inspection, dispatch and freight are shown as separate milestones in the order programme.

Questions to settle before buying a Double-drum winch.
Use the answers to prepare one complete technical and commercial brief.
Discuss your winch requirementAre both drums automatically synchronized?
No. Linked or independent movement is an engineering choice. Specify the allowable line-speed difference, start/stop sequence, braking and emergency response in the project brief.
Can I add the two drum ratings together?
Do not assume the combined safe load is the sum of two catalogue figures. Line angles, load sharing, working layers, simultaneous duty, base forces and controls must be evaluated for the actual rigging.
What details are needed for a useful quotation?
Provide a rope-route drawing with line A and B loads, travel, speed, reeving, load share, operating sequence, duty, anchors, power and destination requirements.
Can one drum operate while the other holds?
That operating state needs to be stated explicitly. The drive, holding brake, control logic and load path are then selected and checked for it.
Is this layout suitable for suspended lifting?
Only after a lifting-specific engineering review. The winch, ropes, brakes, structure, controls, inspection and local acceptance requirements must be specified for that duty.
Which dimensions and documents can be supplied?
Request the selected general arrangement with drum spacing, base and anchor dimensions, rope exits, control schematic and agreed inspection and test documents before production approval.
When will it ship, and what warranty applies?
Production and dispatch depend on the approved two-line arrangement and inspection scope. The formal offer confirms the schedule, minimum order, warranty and after-sales responsibilities.
