During one of the regular SHE committee meetings at this
Westbury concrete plant, an idea was developed for a device
that eliminates the need for a truck mixer driver to stand at
the rear of the truck as it unloads. The site Fitter and Batcher
designed a folding handle that could easily be retro-fitted to the
chutes of all truck mixers irrespective of the type.
The handle removes the driver from the crush area completely
but also enables him to move the chute to fully load a backacter
bucket or the skip of a site dumper. It takes seconds to
extend and folds away neatly on the side of the chute, or can be
removed easily entirely. The simple design completely removes
the risk of crush injury and is cost-effective. The handle can be
home made or fabricated, at a cost of around £50 per unit.
Accessing drum mixers

When introducing a new safety procedure, it is vital for it to be realistic and to go for what
is achievable. Tarmac recognised this when developing a drum entry procedure for its truck mixers. Drivers
were required to remove inspection hatches prior to entry to avoid climbing above the handrails.
However, the SHE committee at Westbury Concrete was concerned that drivers would be reluctant to do
so due to the frequency – and time-consuming nature – of the task.
The area fitter, therefore, designed an access platform with input from drivers and management, complete
with a trap door entry system, wide access steps, power points and water. The design also incorporated
an acid cleaning platform that raises the drivers above ground level to prevent hydrochloric acid running
down the handles of the brushes used to clean the outside of drums and discharge chutes. So successful is
the design that it has been rolled out to a number of other sites.

Truck mixers – pump system for additives
CEMEX > Carlisle Concrete Plant, Cumbria > 01768 860816
Operators and owner-drivers of this Cumbria plant were concerned
about the need, mainly on customers’ sites, to add products to concrete /
mortar after mixing. Drums filled with up to 25kg of liquid chemical had
to be carried up a set of ladders before being tipped into the drum mixer.
The solution was a simple and effective pumping system, which can
be adapted to fit all makes and models. It can also be fitted without
welding or drilling to any chassis
or original steelwork by careful
design of the carry case brackets.
Two 25-litre containers, held in place by a ratchet strap and hooks,
were incorporated into the design – one for the add mix and one
for water to flush the entire pump and pipe work. The galvanised
bund tub is made to hold any spillage or – in the case of a ruptured
vessel, all the contents – to prevent highway contamination. In
addition, a 12mm threaded bung is fitted to the galvanised tub for
drainage purposes if needed.
