A pulley winding handle for turning elevators at Express Asphalt Stockport has eliminated the danger of
trapped fingers and muscle strains. These were real dangers of the previous method – turning the gearbox
pulley by hand or pulling the drive belts. The design for the tool is simple: a clamp plate fixes the handle to
the pulley spokes and is welded to a redundant starter handle for a generator.

Battery charging station

A risk assessment for charging batteries at this Knaresborough quarry
identified that a new charging station was needed with the following
criteria:
• protection for operatives should there be an ignition of gases
• good ventilation
• battery away from sources of ignition
• clear definition
• positioned away from work areas
• bench at a suitable height to reduce the risk from manual handling
• clear instruction and training for the new facility.
Thus a well-ventilated charging cabinet with twin compartments was
installed. The battery to be charged is placed on one side of the cabinet,
with the charging equipment and electrical switchgear on the other. An
extractor fan mounted in the battery-charging compartment provides ventilation.
A sliding door made from a shatterproof plastic draws across the front of the cabinet and allows only
one of the two compartments to be open at any time. The top compartment is a window to view the
operation and the lower part contains two hand holes that enable the charger grips to be connected
and disconnected from the battery with the operator safely behind a protective screen. The power to the
charger is only turned on or off with the door closed.

Handrailing around screen tops
Midland Quarry Products > Cliffe Hill Quarry, Leicestershire > 01530 239 458
The screen tops at Cliffe Hill Quarry are regularly used as work platforms. Although less than two metres
above the ground, these slightly sloping surfaces were deemed to present significant risks of tripping and/
or falling.
Handrailing components were anchored to the “fixed” sections of the screen support structure to avoid
heavy vibration and unbalancing the screen drives.

Temporary guarding
Hanson Aggregates > Builth Wells Quarry, Powys > 01982 553608
At Hanson Aggregates’ Builth Wells Quarry, the problem has been addressed of ensuring the safety
of personnel during periods when sections of flooring or permanent guarding have to be removed for
maintenance access, etc. The “Builth Barrier” is easily adjustable in length, width, height, and shape (fully
hinged). The flexibility of the design also allows folding flat and therefore easy storage.
