Hydraulic cable winch VT.KLH-2/120, VT.KLH-2/200

Kołowrót hydrauliczny

The VT.KLH-2/120 and VT.KLH-2/200 hydraulic cable winch is designed to transfer (pull and lower) heavy parts of mining machinery and equipment during operation in mining works, therein as a supporting device in reinforcement and liquidation of discharge walls. It is used to pull out and position shields of powered roof supports and other machinery and equipment elements in longwalls and faces. The winch can be used to haul transformers, various heavy electrical devices and as a support tool for heavy equipment reloading as well as for transportation, where significant towing power is required. The winch can be used with the maximum inclination of 45°.

The winch can be used in rail transport to shunt cars along flat and inclined tracks (up to ± 4 degrees) and along tracks with steeper inclination with the provision of a self-braking system for the means of transportation or appropriately securing the tracks.

The winch is capable of working with other winches in a double system, according to the transport system documentation created by the user.

Optionally, the VT-80 or VT-200 cable-directing roller can be supplied on demand. The cable-directing roller is used to change cable direction – it allows cornering the cable in the range of 0° to 180° by banding the reel. The roller is an auxiliary device in cable transport systems. It is commonly used in places that are difficult to access, where “straight” towing is impossible due to the lack of space or for safety reasons.

The VT.KLH-2/120 and VT.KLH-2/200 hydraulic cable winch may be used in underground mines in the fields without and with methane content categorised as a, b or c class of methane explosion hazard as well as A or B class of coal dust explosion hazard.
