A chassis (3) is mounted on two wheels and has drawgear and has a hopper (1). The hopper has two rails (2) on its base. Similar rails (10) are fitted to the chassis. Four arms (6) form lazy tongs and connect the hopper and chassis. Rollers (9) are provided. A jack (5) also connects the hopper and chassis. A hydraulic pump can raise the hopper until roller (9) are stopped by a hook. Further use of the jack tilts the hopper around pivots at (8). A chain (7) is provided as a safety measure. To restore to normal position pressure is released from the jack and the hopper returns, under its own weight.
