Tightening torques
The tightening torques are based on a medium friction coefficient of
µtot=0.125. They must be followed for screw joints.
For special connections, heed the tightening torques specified in the respec-
tive drawings.
Guards
Fixed guards as defined by the Machinery Directive 2006/42/EC are exclu-
sively for the protection of persons against the hazards arising from moving
parts (Machinery Directive 2006/42/EC: Annex 1 Nos. 1.3.8.1 and 1.3.8.2).
The machinery directive stipulates that these protective devices must be
attached by means of captive fasteners so that they remain attached to the
protective devices or machine when removed.
TRANSNORM provides captive fasteners for protective devices if the oper-
ating company needs to remove a safety device from a machine. This is
necessary for maintenance and cleaning. Generally no hazard is posed by
the loss of captive fasteners when a fixed guard is removed from the
machine by technical personnel to conduct repairs.
TRANSNORM uses fixed guards to provide effective protection in dangerous
areas. Such protective devices may include covers
that are rarely/never removed
that are opened/removed only by technical personnel
that cover a low risk potential only
