Product DescriptionThe Tirfor® Principle
A Tirfor® has neither wheels nor gears
Two jaws alternately pull the wire rope and the load in the required direction, just like pulling on a rope with both hands
The jaws are self clamping, proving immediate and gradual safety the heavier the load, the tighter they clamp
A release mechanism allows the wire rope to be inserted between the jaws
Multifunction:
Work can be performed in any position; horizontal, vertical or at an angle
There is no limit to the length of wire rope
The capacity can be increased
Safe and Reliable:
Constant control of the load during lifting and lowering with accuracy to within one millimetre
When stationary the load is automotically distributed between the two jaw units
Overload safety device
TU range approved for lifting personnel in most countries
Increased capacity:
Using the sheave block technique, the capacity of the RIRFOR can be increased by a factor of 2,3,4 or more (see diagrams)
The figures given must be multiplied by the nominal capacity of the device
When calculating the working load limit, include a loss of around 4% per sheave, due to the friction of the sheaves
