Tackling the issue of lifting in a restricted space

The problem

Despite having a manually height adjustable pallet lifter, a host of manual handling issues remained on a bottle packing line. Problems were encountered with moving the pallet lifter; the pallets of unlabelled bottles and transferring bottle trays to the turntable supplying the labeller.

Person manoeuvring boxes on pallet lifterLimited space on line and in the production area meant turning the manual pallet lifter was very difficult and to do so operators often pushed the pallet forks with their feet or pulled with their arms. Significant force, up to 17kg, was required to move and turn the pallet lifter when full (up to 385 kg) while up to 14kg was required to pump the pallet up to the correct working height. This put operators at an increased risk of strain to their back and upper limbs.

In addition, the pallet was not always adjusted to the correct height as doing so involved walking around to the other side of the lifter. This led to operators bending down and stretching to transfer trays resulting in greater risk of injury. Subsequent modification of the line layout reduced the labeller operation to a one person task but the redesign did not create any extra working space.

Electronic pallate truck

The solution

Following a truck selection process involving three suppliers, an electric truck was purchased. This is not only light and easy to use but can also be turned in a restricted space. The truck, which is re-charged on line via a 240V socket and has a single mast permitting optimum visibility, has been fitted with shorter forks and an automatic height selector.
