Winches – Versatile tools for lifting, lowering, and tensioning
Winches are indispensable tools. They are primarily used for lifting and lowering loads at low speeds as well as for tensioning ropes. Depending on the application, they are used in different designs, including stationary and mobile winches. In most cases, winches are designed as drum machines capable of holding the rope in multiple layers. A spooling device is used for orderly winding and unwinding. Drums without rope grooves are also possible.
Applications of winches
- Stage winches
These winches are used for moving stages and supporting structures of grab systems. Several stage winches can also operate together in synchronized mode to move a stage. - Tension winches
Tension winches are used for tensioning guide and friction ropes. - Shaft winches
Shaft winches are used to safely attach and detach materials, equipment, or plummets in shafts. - Winches for rope installation
This includes, for example, friction winches as well as drum winches used for installing and removing ropes. They are capable of applying a retaining force so that the rope can be installed under pretension.
OLKO winches are characterized by the following features:
- Stable construction for reliable operation under load,
- Disc or drum brakes
- Brake actuation hydraulically, pneumatically, or with electrohydraulic lifting devices
- Precise control for controlled lifting and lowering,
- Robustness against environmental influences when used underground or outdoors.
