Every day, hundreds of different tasks are completed by people in all sectors, requiring the use of load-shifting trolley systems.
Designers and manufacturers continue to produce a variety of trolleys and hand trucks in response to this demand.
With options of trolleys, hand trucks, load shifters, and dolly carts to A-frames, scissor lifts, porta-lifts and easy-tilts, choosing the right trolley can make all the difference to the operations at hand as well as the profit to be gained from them.
Trolleys are available in a wide range of designs and styles to suit all situations and applications. These include cylinder trolleys, sack trucks, couriers and order pickers to name a few.
When it comes to trolley buying, it is critical that the selected trolleys match the actual application.
Although there are no current Australian Standards guiding the manufacture of trolleys, there have been many studies into safe and recommended trolley design.
- Lawson, Potiki and Watson (1994, p. 55) found that hand-pushed trolleys should be at least 80mm narrower than the narrowest doorway, while towed trolleys should be 500mm narrower.
- When purchasing a new trolley, Drury (2010, p.33) advises selecting a strong and rugged construction, with steel parts well-protected and wheels that reflect the ground conditions. This means selecting small swivel wheels for interior environments, and large diameter wheels with pneumatic tyres for areas where the ground is uneven or muddy and the loads are likely to be heavy.
- Lawson, Potiki and Watson (1994, p. 55) state that trolley length should be between 1.5 to 2 times the width for the trolley to track smoothly around corners.
- Both Drury (2010, p. 33) and Lawson, Potiki and Watson (1994, p. 55) advise checking the various heights of the trolley before purchase. This means checking for appropriate loading heights and convenient handle heights for pushing or pulling the cart or barrow. It is recommended that a maximum height of 1400mm (including the goods to be carried) be maintained for a clear line of sight.
- Fallshaw Wheels and Castors recommends:
- Weight of the trolley should be 15% to 20% of the load to be carried
- For the castor to function properly, the frame of the trolley must be strong enoughto hold the castor head truly vertical so it can swivel freely
- The frame must not bend under any impact. The most common cause of castors not tracking properly is that the mounting has twisted off square
