Tractel Subito Manual Operation Temporary Use Suspended Working Seat With Fall Arrest options. Max 30m Working Height

Compact, lightweight and stable, the SUBITO work seat is a fast and secure method of access for many inspection, maintenance and cleaning jobs.

The SUBITO work seat conforms to CE standards. The steel frame combines a folding seat for compact storage. Two stabiliser wheels (optional) run along the facade providing good stability of the seat and ensuring that it does not spin.

Features

• The SCAFOR manual hoist has a single wire rope and together with the retractable lifeline (AC04/20) provides a secure and reliable access system, essential for man-riding equipment. Both handles are used for lifting whilst lowering only requires operation of one handle.
• The lifting height is up to 20m although, using a larger model of retractable lifeline (AC04/30) the height may be increased to 30m.
  The length of lifting wire rope must be appropriate for the suspension height.
• For increased safety and reassurance, a cable-clamp end stop is fitted at the free end of the wire rope to prevent it unintentionally passing through the hoist.
• Designed for working at heights of upto 20 metres
• Equipped with a SCAFOR manual winch, this harness is then approved for lifting people.
• With its safe, easy, and efficient operation, the SUBITO boatswain suspension harness was specially designed for inspection, maintenence and cleaning.

Operation and Technical Specifications

The SUBITO work seat conforms to CE standards. The steel frame (1) combines a folding seat (3) for compact storage. Two stabiliser wheels (4) (optional) run along the facade providing good stability of the seat and ensuring that is does not spin.

The SCAFOR (2) manual hoist has a single wire rope (9) and together with the retractable lifeline (5) (BLOCFOR B20) provides a secure and reliable access system, essential for man-riding equipment. Both handles are used for lifting whilst lowering only requires operation of one  handle.

Without its wheels, the system does not have to be dismantled and may be transported in an estate car. If required the stabiliser wheels may be easily removed by 2 bolts.

Safety Devices

The SCAFOR hoist has a service brake which operates automatically as soon as the operator release the handles.

The safety device consists of two jaws which grip the lifting wire rope at all times. When the seat is moved up, the jaws open sliding over the wire rope. When the seat is moved down, the jaws prevent all movement and the operator must manually keep the jaws open in order to perform this operation (re. chapter 4.4. Operation of SCAFOR). The wire rope clamp end stop (7) prevents the seat from coming down beyond the length of the lifting wire rope.

Fall arrest device with winder

A fall arrest device with a wire rope winder, type BLOCFOR, fixed between the point of suspension and top part of the steel frame, is provided to guarantee the safety of the operator in the event of a fall. During normal operation, the wire rope of the fall arrest device operates in conjunction with the upward and downward movement of SUBITO.

The automatic operation of the fall arrest device may be triggered for two reasons:

1. breaking of lifting wire rope.
2. overspeed following a failure of the hoist.

In the above cases, an emergency procedure must be started to rescue the operator on SUBITO. The operation of the fall arrest device should be entrusted to a single operator who will be in charge of it once he has been trained to handle and maintain it. The same applies to connectors (safety hooks) fixed to the fall arrest device BLOCFOR.

Safety belt

The user is harnessed in the seat by the safety belt (6) attached to the structure.

Components

SCAFOR Hoist Installation

Fix the hoist by inserting the top part into the frame guide pin and moving it from top to bottom in relation to frame (A), (Fiig.3). Then fix the lower part of the hoist to the frame using twi bolts (screw + Nyloc bolt) supplied with the SCAFOR hoist (B).

Insert the Lifting Wire Rope

This operation requires two operators, one near the seat and the second on the roof.

Ensure That

• the diameter of the lifting wire rope (9) correspond to the diameter shown on the SCAFORTM hoist technical plate,
• the length of wire rope is sufficient for the application and the end of the wire rope.

1. Set the seat vertically under the suspension point.
2. Pull the lifting wire rope (hook side) on to the roof using a cord.
3. Fasten the hook to the suspension anchor point.
4. Fasten the upper safety hook (10) of the BLOCFOR fall arrest device to the second anchor point of the suspension.
5. Fasten a cord (A) to the lower safety hook (11) of the BLOCFOR fall arrest device.
