HNZ Hydraulic Tensioning Equipment
Serves as follows for tensioning the transport chain up to the necessary pre-stressing and for handling the transport chain, for its release on disconnection.
The basic width of a trough is 1500 mm and by means of two hydraulic cylinders (or stretching bolts) it is possible to elongate it up to the length of 1 700 mm. The trough construction enables to lay it both on the footwall and to suspend it on a suspension railway as a component of a suspended gathering scraper conveyor.
|Type mark:||Width:||Use for scraper conveyers:|
|HNZ 01||600 mm|
|HNZ 02||700 mm||C3K 228/732|
|HNZ 04||800 mm||C3K 228/800, C3K 228/832|
NZ-F02 Tensioning Equipment
The NZ-F02 equipment is determined for tensioning the transport 26 x 92 a 30 x 108 chain with a pitch of 100, 120 or 200 mm in case of the scraper conveyors. It serves as an auxiliary equipment for tensioning the chain on its disconnection followed by connection by means of the chain couplings.
The NZ-F02 equipment is ready to be used after putting the suspensions into the scraper and securing this position by a hinged pin between the chains. The equipment guarantees a safe disconnection of the transport chain, this firstly by the construction of the suspensions that are secured on the scraper and secondly by controlling them from a safe point inside the conveyor. The pre-stressing regulation is controlled by a pressure gauge thats an integrated part of the hydraulic distribution system. Advantages are the possibilities to be used in any point of the conveyor and also a small weight of the equipment.
