DESCRIPTION
2.1.
Operation
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 ac-
cess 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.

2.3. SAFETY DEVICES
To ensure safe operation without
danger to personnel, the seat is
fitted with the following safety
devices:
2.3.1.
Service brake
The SCAFOR™ hoist has a service brake which ope-
rates 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. Opera-
tion of SCAFOR™). The wire rope clamp end stop (7)
prevents the seat from coming down beyond the length
of the lifting wire rope.

2.3.2. Fall arrest device with winder
A fall arrest device with a wire rope winder, type BLOC-
FOR™, 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:
a) breaking of lifting wire rope.
b) 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™.
A BLOCFOR™ which has
functioned following a fall must
be removed from service and
inspected by the manufacturer or an
approved repair agent.
2.3.3. Safety belt
The user is harnessed in the seat by the safety belt (6)
attached to the structure.
