There is a WHEEL BARROW TROLLEY offered by us that is designed to distribute the weight of its load between the wheel and the operator, so enabling the convenient carriage of heavier and bulkier loads than would be possible were the weight carried entirely by the operator. It is a piece of equipment used to carry heavy and cumbersome items, frequently we ll see the puncture proof variety used on a builder s yard. The Wheel Barrow Trolley is very effective and durable.
