Abstract

A hand truck (10) comprises a frame (12), a platform (14) for carrying a load, an axle (26), two wheels (16) mounted on the axle (26), axle guide members (42), and biasing means (30). The axle (26) ismoveable along the axle guide members (42) to move the axle (26) relative to the platform (14). The biasing means (30) compresses to resist tilting of the hand truck (10).

Description

technical field [0001] The present invention relates to trolleys, in particular but not limited to a trolley having an axle movable relative to the loading platform of the trolley. Background technique [0002] Trolleys, also known as dollies, wheelbarrows, sack carts, and dollies, are commonly used to move heavy loads from one place to another. [0003] The trolley acts as a lever, enabling the user to generate sufficient moment to lift a load placed on the trolley platform that might otherwise be too heavy to lift. However, if the load is particularly heavy, or the user cannot easily or safely generate a sufficient moment to lift the load due to a short or weak user, another user or a different machine may be required to Move loads. [0004] The retrofitting of trolleys is generally known to include the retrofitting of additional components, such as an additional set of wheels on the frame pivotable relative to the trolley, enabling it to pass stairs, and leverage means ...
