Tirfor Lifting & Pulling Machines

More than 30 years of manufacturing experience is behind the TU-TIRFOR range of lifting and pulling machines. Available in three sizes – 800kg to 4000kg – they offer
portability, safety and precision. The unique rectilinear operation enables the machines to operate in any direction and for any height of lift or length of pull. Lifting and
pulling power can also be increased with the use of sheave blocks. Tirfors are used in applications across industry, including civil engineering, construction, mining,
pipe laying, shipbuilding, agriculture and forestry.

• Tirfor hoists have two ‘U’ shaped jaws blocks which preserve the cylindrical form of the wire rope to ensure there is no deformation and very little wear of the rope
• The Tirfor system provides high mechanical efficiency which ensures ease of operation and longer service life
• Accidental release is preluded and the self-gripping action of the jaws is maximised
• Universal – It is a hoist, winch, tensioner, binder, ratchet – and much more
• Portable – It has the lowest weight to capacity ratio of any hoist or winch with comparable capacities
• Unique – It’s unique wire rope gripping system provides unlimited pulling length or lifting height and pinpoint accuracy in positioning and work load
• Unmatched safety – It is simply designed and ruggedly constructed with the finest alloy heart-treated steel. The load is automatically held securely, with a large overload margin of safety
• Indispensable – for all construction and maintenance jobs. It is used daily by millions of people all over the world.

INCREASE OF LIFTING AND PULLING POWER
TIRFOR machines, used in conjunction with sheave blocks, will efficiently solve most of your lifting and pulling problems.
By using sheave blocks on the hauling rope, the nominal capacity of TIRFOR machines can be multiplied 2x, 3x or even 4 x as per below.
As a rule it is not difficult to figure the number of line parts to be used for the given load. It is, however, important – especially when there is no greater number of line parts – to take into account the friction in the sheaves, which can have a non-negligible influence on the strain exterted on the hoist and the top anchoring hook of the machine.
