1 GENERAL INSTRUCTIONS
Each pair of safety gears supplied is factory tared according to the required conditions of use: Total mass
(P+Q) and guide rails’ thickness. These features are indelibly displayed, along with the standardisation
password and serial number; on the protection plates on top of the safety gear boxes (see section 2.1).
It is strictly forbidden:
a) To combine and assemble safety gear boxes with different serial numbers.
b) To use a pair of safety gears for installations with characteristics different from those indicated on that
pair of safety gears’ protection plates.
c) To handle any of the safety gear’s components.
DYNATECH DYNAMICS & TECHNOLOGY, S.L. cannot be held responsible for the damage caused due to
the non-observance of any of these general instructions.

2.2 SAFETY GEAR’S FEATURES AND USE
a) The guide rails to be used should be machined. Allowable tolerances for guide rail thickness should
be within the limits set by the standard: ISO 7465:2007.
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.
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.
