Different Types of Towing Winch for Sale
According to the drive mechanism, the winch can be classified into electric driven winch and hydraulic driven winch.
The electric towing winch can be driven by single-speed, two-speed motors or the advanced variable frequency drives. The local control panel is located near the winch. Remote control is also available as optional.
Electric towing winch parameters:
- Load capacity: 10 ton – 100 ton
- Drum capacity: 200m- 1500m
- Speed: 5m/min – 20 m/min
- No. of drum: single
- Certificate: BV, ABS, DNV, RMRS, etc
The hydraulic towing winch is mainly used for rescue, salvage, towing and mooring operations of tugboat, workboats, AHTS vessels, Multipurpose Supply Vessels, icebreakers, etc. The winch is connected to the hydraulic circuit that drives the drum. Marine hydraulic towing winch can be designed with a high load capacity, a great choice for offshore vessels or platform operations.
Hydraulic towing winch parameters:
- Load capacity: 5 ton – 300 ton
- Drum capacity: 200m- 1500m
- Speed: 4.5m/min – 20 m/min
- No. of drum: single or double
- Certificate: BV, ABS, DNV, RMRS, etc
According to the number of drums, the winch can be divided into single drum winch, double drum winch and triple drum winch in waterfall arrangement.
To select the right winch for your application, you first need to address the following information:
- What is the purpose of the winch?
- What is the capacity of the winch?
- What drum capacity is required?
- Electric or hydraulic drive?
- what is the maximum bollardpull?
- What is the supported load?
- Do you need a rope spooling device?
- What structure formdo you prefer? single drum, double drum, triple drum, coaxial or waterfall arrangements?
- Do you need a warping head?
- Winch working environment or conditions
- Does the winchneed to be certified by the classification society?
You can discuss your winch requirements with one of our experts and get useful advice from us.
How to Size A Towing Winch
In order to calculate the size of the winch, you need to know the load or maximum capacity it can bear. This load must be higher than the maximum weight you need to lift or tow to avoid any accidents. In general, it is necessary to provide twice the traction capacity of the load to be towed.
You also need to consider that, according to the length to be pulled, the rope will be continuously wound on the drum, and the winch manufacturer will indicate the capacity of the winch on the first layer. As the rope winds, the winding diameter and winch speed will also increase. At the same time, due to the increase in torque associated with the increase in winding diameter, the towing capacity of the winch decreases.
If you want the winch to be able to lift the set load, make sure that the load indicated by the manufacturer is not just a traction load (it can be pulled but not lifted).
The winch speed and drum diameter must be adapted to its purpose. These two factors determine the traction speed of the winch. You need to distinguish the rotation speed of the idle winch from the towing speed under full load.
