Conveyor blockage access platform
Lafarge Aggregates > Kiplin Hall Quarry, North Yorkshire > 01748 812117
Staff at Kiplin Hall Quarry have addressed the potential safety hazards involved with clearing the clay
blockages which occur when the jaw crusher flattens the material which then builds at the base of the
conveyor chute.
The team designed and constructed a portable access platform, situated at the base of the conveyor
where the blockage arises, and provides a safe, raised level surface from which operatives can work on the
blockage. This reduces the need for stretching and overreaching, thus lowering the risk of injury.

Maintenance for dryer drum
Tarmac Northern > Coxhoe Quarry, County Durham > 0191 3770611
Tarmac Northern has developed a system for improving the routine maintenance task of tracking the dryer
drum. Manufacturers’ recommendations stipulate that the drum must be tracked under load and whilst in
operation. This requires personnel to stand within the perimeter/distance guarding whilst the dryer is in
operation.
Tarmac Northern designed and installed a remote hydraulic tracking system. The system utilises a pair of
hydraulic rams, installed to both feed end trunnion bedplates. The rams are connected to a centralised
hydraulic power pack, positioned under the dryer. Operation of the system is achieved by remote control
from outside of the guard.
This system could have major benefits to the whole industry as most older (and even some newly
designed) plants still incorporate manual adjustment equipment which cannot be accessed unless
personnel access the inside of the perimeter/distance guarding surrounding the dryer position.

Safer hanging of hoses
Lafarge Aggregates > Marlow Readymix Plant, Buckinghamshire > 07740 563244
The safety team identified a risk of slips, trips and falls caused by drivers and plant supervisors not
re-hanging water hoses used to fill up ready-mix trucks after use.
Firstly, the company introduced bungees on each hose so that, once removed, the hose is gently pulled up
into the air and out of harm’s way. Whilst this solution worked successfully, the bungee ropes proved not
to be very long lasting. In response, the west London cluster also introduced retractable hoses which were
more durable and have been introduced throughout the southern region.
