摘要
A two-wheeled trailer carries an adjustably rotatable crane to allow loading and placement of grave headstones by a single worker. The trailer provides a ladder type frame supporting a bed with upstanding sides and openable tailgate. The frame is supported for locomotion by a two-wheeled truck and has tongue structure with vertically adjustable supports. The tongue structure immediately forwardly of the body supports a crane base that journals an angulated crane mast carrying a boom structure, with adjustable braking mechanism communicating between the mast and base to regulate rotation of the mast. The crane mast carries a hoist to move a cable supported by a sheave at the outer end of the crane boom for vertical lifting at the end of the boom. The trailer frame has an adjustable outrigger support to prevent vehicle tipping on inclined support surfaces or when supporting laterally extending masses.
