Self-cleaning hopper grid
CEMEX UK Materials > Pendean Quarry, West Sussex > 01730 813950
Following a risk assessment of gaining access to the hopper
grid to remove clay and deleterious material, a self-cleaning
hopper grid has been designed and manufactured by the
workforce, which avoids manual handling and can be
adaptable to any type of hopper.
The loading shovel approaches the hopper and puts the
bucket blade under the lifting bar. The operator then flicks the
bar with the bucket blade causing the grid to pass the point
of balance, which causes the finger bars to move forwards,
removing clay and deleterious material before the spring
mounted stops cause the grid to return to its seating.

Following a review of isolation procedures and site rules, this quarry has introduced a new training
package and a series of practical innovations.
The safety team purchased a new lock-out station consisting of numbered and colour-coded locks for
issuing padlocks to contractors and employees when multiple point isolation was required.
All employees were issued with a unique numbered padlock and instructed to retain the key at all times.
The team also issued isolation identity tags to determine who has isolated the plant and on what part
they are working.

Workshop parts cleaner trolley
Foster Yeoman > Botley Depot, Hampshire > 01489 784438
The parts cleaner at this site was located within a bund to catch any spillage,
but this made it difficult to change over the barrels, and meant that all parts
and tools had to be carried from the work area when they needed cleaning.
To improve safety, a cut-off drum was fitted with braked castor wheels to
make the cleaner mobile. This enabled the cleaner to be moved to where it
was required – removing the need to carry oily and greasy parts and tools
across the workshop. The parts cleaner could also now be moved to a safer
position to change the barrel with mechanical lifting equipment, reducing
the amount of manual handling involved in its maintenance.

Cleaning the cement discharge pipe
Lafarge Aggregates > Aldershot Readymix Plant, Hampshire > 07803 953990
The staff at this plant have devised a method to reduce the manual handling risks associated with clearing
the excess build up on the cement discharge pipe from the cement weigh hopper. The heavy pipe was
originally only accessible at height, and built up cement had to removed with a hammer.
To reduce both weight and handling risk, the metal pipe was removed and replaced with a Linatex pipe.
The material properties of the Linatex mean that cement does not now build up so quickly, and that the
pipe can be regularly replaced rather than just cleaned.
