These will benefit any hauling system by reducing friction and are essential when building a system to produce a mechanical advantage for lifting heavy loads. It must be remembered here that even in a simple lifting system, the anchor attached to the pulley will sustain a load equal to twice the load being lifted. In more complex hauling systems generating large amounts of mechanical advantage very high loads may be applied to the anchors ( and the pulleys ). For personal mountaineering, caving and paddling (bank rescue) use look at Petzl Swing Cheek or Fixed Side Pulleys or as an ultra light weight emergency item the Pulley wheel could be considered.
For rescue, industrial, and high rope course applications there are many options with either single or double wheels, with bearings, and with fixed or swinging sides.
If you are looking for devices designed for ziplines and Tyrolean traverses, see the Petzl Tandem series.
The versatile Minitraxion and the Protraxion are pulleys that incorporate a rope grab for simple and straightforward hauling. They can also be used for ascending ropes.
The Transf'air 1 pulley is a pulley designed for load deflection and hauling. Single pulley with a mobile flange, it is perfectly adapted to ropes with large diameters, the mobility of the flanges facilitating the positioning of the pulley at any point on the rope. The good performance is ensured by a sheave mounted on a bronze ring. Its durability is reinforced by a stainless steel shaft and washer. And to ensure traceability, each pulley has an individual number.
The Beal Transf'air 1B pulley is designed for load deflection and hauling. Single pulley with a mobile flange, it is perfectly adapted to ropes with large diameters, the mobility of the flanges facilitating the positioning of the pulley at any point on the rope.
The Beal Transf'air 2B pulley is a pulley designed for load deflection and hauling. Twin pulley with a mobile flange, it is perfectly adapted to ropes with large diameters, the mobility of the flanges facilitating the positioning of the pulley at any point on the rope.
A highly efficient double pulley with ball bearing mounted sheaves, the swivelling action of the side plates allows the pulley to be positioned anywhere along the rope. Ideal for intensive use with large diameters ropes.
The Beal Transf'air Fixe B is a pulley with fixed side plates and ball bearings for optimal efficiency. Its compact and lightweight nature make it easy to handle. Allows a pulley system to be set up by adding a component such as an ascender.
Everyone's favourite Pulley! The Triple Attachment Pulley by DMM forms an integral part of the renowned Hitch Climber System and is a firm favourite of working at height professionals the world over. The three hole construction makes rigging and organising much simpler and allows for off-centre hanging to minimise rope to pulley friction.
With hardly a straight line in sight, the hot forged curves and fairlead flares of DMM's Pinto Pulley make for an ultra efficient, ‘textile friendly’ environment. Clip, hitch, splice or thread the anchor holes or the becket to give numerous work and rescue configurations (textile attachments can help minimise any torsional build up in closed systems).
Slightly larger than the Pinto and accommodating a larger rope size, the DMM Pinto Rig also has a high efficiency roller bearing giving ultra smooth operation. With hardly a straight line in sight, the hot forged curves make for a ‘textile friendly’ environment.
The DMM Pinto Rig Spacer is an essential component for Pinto Rig applications where textile connecting elements tend to compress the side plates.
The DMM Pinto Spacer is an essential component for Pinto Pulley applications where textile connecting elements tend to compress the side plates.
The Heightec Aluminium Rescue Pulley is a lightweight, compact swing cheek pulley for general or personal use.
The ALF Climb Assist Pulley was designed for the Challenge Course industry, as a simple method of protecting users on thier way around a High Ropes/Challenge course. It is also a protection solution for workers on towers, masts, Wind Turbines and even in constrution applications where a cost-effective, temporary climb assist solution is required for short duration working.
The ISC Aluminium Prussik Pulley (13mm) with roller bearings is ideal for low loads at high speeds and has tamper-proof rivets, in compliance with CE EN12278 (2007) & NFPA (1983)*.
ISC lightweight Eiger Pulleys are made from high strength Aluminium and fitted with tamper-proof rivets.
All Pulleys in ISC's latest Heavy-duty Prussik range have tamper-proof Rivets, in compliance with CE EN12278 (2007) & NFPA (1983)
