SAFETY GEAR’S FEATURES AND USE
This safety gear may be used with guide rails that have braking surfaces equal to or greater than 25 mm,
provided that the following requirements are complied with:
a) The guide rails to be used should be cold drawn or machined. Allowable tolerances for guide rail
thickness should be within the limits set by the standard: ISO 7495:197.
b) For lubricated guide rails, the recommended lubricating oil is the type used for machines according to
ISO VG 150, although other viscosities within the margins established in ISO-VG may be accepted.
c) This safety gear can be used up to a maximum tripping speed of 2.5 m/s.
d) Allowable guide rail thicknesses: 7
– 16 mm.
e)
Guide rail’s braking surface equal to or more than 25mm.
This safety gear may be used with guide rails with braking surfaces equal to 20 mm (for example T 65 A),
provided that the following requirements are complied with:
a) The guide rails to be used should be cold drawn. Allowable tolerances for guide rail thickness should
be within the limits set by the standard: ISO 7495:197.
b) For lubricated guide rails, the recommended lubricating oil is the type used for machines according
to ISO VG 150, although other viscosities within the margins established in ISO-VG may be
accepted.
c) This safety gear can be used up to a maximum tripping speed of 1.5 m/s.
d)
The guide rail’s braking surface is equal to 20 mm.
2.3 RANGE OF USE
Please find below the standard P+Q table. The rated values are displayed in bold in the middle row. The safety
gears, when supplied, are set to the default rated value; however, they can be used in installations with P+Q
values within the upper and lower limits.

3 INSTALLATION AND ADJUSTMENT
3.1 ASSEMBLY ON THE FRAME
The
holes should be made on the frame’s uprights to secure the safety gear, according to the dimensions and
position displayed in the safety gear drawings attached (DYN 05.C001.01 / DYN 05.C002.01), ensuring that
the guide rail’s axis is centred with the frame.
