1. FUNCTIONS AND DESCRIPTION
The Stopfor M is designed to protect users from
falling when working on a sloping plane (roof) or
a horizontal plane (for example a
terrace with no guard rail).
The Stopfor M is a sliding rope grab mounted on
a textile rope.
The user operates an
operating lever to move the device along the
rope, and once the work position is reached, the
operating lever is released and the Stopfor M
grips the rope.
The fall protection system consists of the
components described below.
1.1 Fixed anchor point
(see section 2.1 Installation)
1.2 Textile rope
The 14mm diameter polyamide textile rope is
supplied in lengths which are multiples of 10
metres. An eye is made at one end, to attach the
rope to the anchor point, and the other end has
a stop splice to prevent the Stopfor M being
accidentally desengaged from the rope.
The breaking strength of the textile rope is grea-
ter than 40 kN.
1.3 Stopfor M
The red operating lever (1) is operated by the
user to release the cam (3) and allow the
device to move along the rope (8).
The cam, which forms part of the operating
lever, grips the rope using a strong spring. If the
user applies a force on the lanyard, the grip of
the cam increases.
The clevis has an anchor point (2) for
attaching the lanyard.
The casing is hinged and can be opened to
insert the rope in the Stopfor M. The casing is
closed using a serrated button (4) and a
threaded screw on the opening cover (7) side
which is screwed into a nut crimped on the
casing. Two simultaneous operations are
required to open the casing: press the release
lever (6) and unscrew the serrated button (4).
An upside-down mounting prevention system,
created by a washer which moves under the
effect of gravity and positions itself to face a
groove, enables the casing to be closed, if the
device is correctly fitted on the rope.
1.4 Lanyard
Two types of lanyard are available: a 12mm
diameter polyamide rope lanyard, and a 27mm
wide polyester webbing lanyard. The length of
both is 0.9 m.
The breaking strength of the lanyard is
greater than 22 kN.
1.5 Connectors
The connectors supplied with the lanyard have
a breaking strength greater than 22 kN.
The approved connectors are the M10, M41 and
M42.
2. INSTALLATION
2.1. Anchorage to the structure
The textile rope is fixed to the anchorage point
by its eye and a connector.
