Features
- Closing by spring force with toggle lever system – adjustable by throttle
- Opening by hydraulic-cylinder (Hydraulic power unit is integrated)
- Hand pump for emergency operation (manual) is supplied (standard)
- Automatically closing function in case of power failure
- No loss of restraining / holding force due to toggle lever transmission resulting from e.g. wear of clamping jaws (permissible measure)
- Limit switch position control system “Clamp open”, “Clamp close” and alarm signal “worn clamp jaws”
- Position control switch for “Clamp is in lifting position / Crane travel is possible
- Vertical movement compensation of + 40 mm up to – 20 mm
- Lateral compensation for rail misalignment of ± 25 mm with integrated lateral guidance system during lowering
- During crane operation all parts of the clamp are positioned above the rail system / Therefore no wear of any components during crane operation
- Guide rollers for guide the storm brake on the rail as used at standard type VZFH will not be integrated into type VZFH-HVZ (wear reduction, reduced maintenance and follow-up costs)
Technical benefits
- Particularly suitable of fast moving crane systems
- Strongly reduced maintenance / follow-up costs
- No contact to the rail during crane travel
- No loss of restraining / holding force due to toggle lever transmission (resulting e.g. wear of clamping jaws)
