Tractel "Scarfor" Lightweight Manual Operation Manriding Hoist as Commonly Used to raise Access Platforms - 400kg Capacity
Manriding hoist with integral blocstop for use with secondary safety rope, Safe Working Load 400kg.
The SCAFOR is a lightweight manual hoist which has been especially designed for light suspended platforms fitted with two hoists or for bosun's chairs or one-man cradles fitted with a single hoist.
The wire ropes (lifting and safety) are not stored within the unit; therefore the working height is only limited by the rope's length.
SCAFOR is in standard version with centrifugal brake (models 406C and 408C) for mounting on any stirrup (fixed or articulated) as well as for bosun's chairs or one-man cradles.
The SCAFOR hoist can be fitted to
- painter's cradles,
- bosun's chairs and one-man cradles,
- platforms with fixed or articulated stirrups.
The SCAFOR fits either directly to the stirrups of our ALTA cradles or with an adaptor to stirrups of other platforms. The lifting rope as well as the safety rope pass through the machine.
The principle of the wire rope passing through the machine gives the SCAFOOR three important advantages:
- constant effort on the operating handles whatever the height of lift (no drum on which to reel the wire rope);
- unlimited height of lift with fast and easy insertion of the appropriate length of wire rope;
- long operating life of the wire rope which is coiled on a separate reeler, with less risk of injury.
Also, with the design of the SCAFOR, it is:
- lightweight (11 kg);
- compact (see drawing);
- easy for testing and maintenance; and has,
- long working life.
The self-gripping mechanism of the SCAFOR exerts a grip on the rope which is proportional to the load being lifted. The integrated safety mechanism with the SCAFOR automatically locks onto the safety rope when there is no load on the lifting rope, or should there be a sudden
descent of the platform, then the centrifugal brake system comes into operation. In an emergency, there is the red lever which locks the jaws onto the safety rope.
