Storm brakes

PATENTED: Type VZFH-HVZ

With lifting and positioning function.

Especially suitable for high speed crane systems - NO crane speed limit
Vertical guidance system (HVS) | NO changing of the angle | No changes of the clamp positioning
Therefore the clamp jams do NOT grind down against the rail during crane travel
Easily changeable clamping jaws
Vertically lifting function
No contact with the rail during crane travel - NO guide rollers / wheels, therefore NO WEAR
Lateral positioning during lowering - patent pending system -
Especially suitable for transverse travels
Up to 640 kN restraining force per clamp
Fail-safe system

Type VZM

Manually closing and opening
Lifting device for clamp shoes
Restraining forces up to 100 kN per clamp
Limit switches monitoring for clamp position
Lateral compensation for rail misalignment ± 7 mm, with floating housing ± 25 mm
Hand lever for lateral positioning
Guidance of floating housing either with rollers or by a hand lever for the lateral positioning (Positioning with hand lever: Area sideways the rails stays free)
No fail-safe system

Type VZE

Type VZH

Hydraulic closing and opening
Restraining forces up to 256 kN per clamp
Limit switches monitoring for clamp position
Using a hydraulic power unit with pressure storage
Optional: Closing via pressure reservoir with power blackout for fail-safe system

Type VZFH-LR / Fail-Safe principle

Closing by spring force with toggle lever system - adjustable by throttle
Opening by hydraulic-cylinder
Permanent guiding on the rail via guide rollers
Restraining forces up to 640 kN per clamp
Vertical guidance system (HVS) | NO changing of the angle | No changes of the clamp positioning
Therefore the clamp jams do NOT grind down against the rail during crane travel
Limit switches monitoring for clamp position
Vertical movement compensation of ± 20 mm
Easily changeable clamping jaws
Lateral compensation for rail misalignment of ± 25 mm
NEW patent pending system type VZFH-HVZ (with lifting and positioning function)
