-Safety regulations for use of concrete product machine-
-Industrial safety-
When or in the area of the mould or tamper head, always secure
tamper head so it cannot come down and switch off pump of
main hydraulic system when carrying out work in the machine.
Holes are provided in the two locking rods for fixing the tamper
head in the upper position. The tamper head is raised above these
holes and the locking pins are inserted in same. After that tamper
head is lowered until it makes contact with the pins. This
procedure stops tamper head from dropping.
- As a general rule, adjustment work should never perform with the machine running. The
sole exception to the above is speed regulation in the hydraulic system by way of the throttle-
type check valves under the directional control valves and adjustment of the pressure
limiting/pressure reduction valve. These valves are installed in the system in such a manner
that they are outside the hazard zone. However, increased care is to be taken when performing
such task.
- When cleaning hoppers, main hydraulic system is to be turned off.
- Wear safety helmet on entering machine pit.
- Caution: Even if the pump is switched off, pipes can be pressurized if the cylinders are
perpendicular and the plunger rods loaded but still not fully retracted or extended. For
example, this is the case of mould, tamper head, hopper outlets and height adjustment.
- In the events of faults, always switch system component(s) concerned to manual and shut
down all hydraulic facilities.
- Switch cabinets are not to be opened until main switch had been turned off.
- Hydraulic system is to be turned off and de-pressured before working on them. Vessels and
pipes are to be drained.
- Never crawl under raised, non-secured filling units. If it is necessary to perform work
beneath such units, secure beforehand with height adjusters.
- Never reach into components that are operating.
