Self-locking - Import export

Trolleys are intended for transporting loads on the tracks of suspended monorails built in underground mining plants in non-methane and methane fields. Trolleys are adapted for installation in the transport set of an apparatus train driven by a self-locking shifting device. They can also be connected directly or in a transport set with a diesel locomotive, maneuvering cart, and other drive approved for use in the underground of mines.

The hydraulic unit is designed to power the self-locking shifting device as well as to power other devices and machines with hydraulic drive. The unit can be operated in underground mines in non-methane and methane fields, in workings classified as "a", "b" or "c" of methane explosion hazard and in workings classified as class "A" or "B" coal dust explosion hazard.

Type 3-201 to 3-212 shaft cable clamps made of stainless steel are used to mount cables in mine shafts, and they have been designed for application in both non-methane and methane fields of underground mining facilities. A prerequisite of correct operation of self-locking clamps is the appropriate clamp choice depending on the cable diameter as well as proper setting of the cable clamping jaws. Type 3-201 to 3-212 clamps are available in an option enabling shaft bracket mounting.
