<p>The trolley has steering arms (5-2) joined by cross pieces (5-1) and with a hand grip (5-3) at the end. This assembly is pivoted on an adjuster plate (6), which is fixed on the body of the trolley (1), without encroaching on the carrying surface. The adjuster plate has holes, and each arm has two holes which overlap those in the adjuster plate. U shaped spring pins are fitted through these holes to give a suitable angular arm position for a particular use. The hand grips are bent at an acute angle to the body, to form steps.</p> |
