Pulley winding handle for elevators<br />

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

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

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

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