Guards
Fixed guards as defined by the Machinery Directive are exclusively to protect
against risks related to moving parts (Machinery Directive 2006/42/EC:
Addendum 1 No. 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, on removal, they remain attached to the protective devices
or machine.
TRANSNORM provides captive fasteners for protective devices if the oper-
ating company needs to disassemble 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 protective device is removed from
the machine by technical personnel to conduct repairs.
TRANSNORM uses fixed guards to provide effective protection in hazardous
areas. Such protective devices may include covers
that are rarely/never removed
that are opened/removed only by technical personnel
that cover only a lower risk potential
that are located on machines that are operated behind a master protec-
tive cover/enclosure
No captive fasteners are fitted on these covers as the risk potential is classi-
fied as low. In this case, the individual parts normally remain assembled
when carrying out repairs on site or in the workshop.
Guards that need to be opened/removed by the operating company for main-
tenance purposes generally comprise the following covers:
Covers on drive assemblies (e.g. protective covers/hoods for chain and
toothed belt drives)
Covers on pinch points if they have to be removed or opened for mainte-
nance purposes (e.g. protective covers for snub rollers)
Bearing covers, covers on rotating parts (e.g. covers on pulley bearings)
Bottom covers (e.g. perforated plates at curves)
