In a wheelbarrow having a bin (1) for the load, a ground wheel (2) at a front end of the bin and a handle (3) at a rear end, the handle (3) has a cam shaped extension (7) which forms a leg for the bin rear end and which is mounted on a pivot (4) carried on the bin. The handle (3) can be released from its normal position and then pivoted forward in the direction of the wheel (2). This action causes rotation of the cam and the bin rear end is lowered to near ground level to allow easy loading of the bin. When loaded the handle (3) can be returned to its position at the bin rear end and the cam simultaneously lifts the bin and load. The load may then be carried and emptied as with a conventional wheelbarrow.

A wheelbarrow comprising: a bin for a load; a ground wheel disposed at a front end of said bin; two handles disposed at a rear end of said bin, each said handle being rigidly connected to the other handle and having a hand engageable end and an inner end; an eccentric-shaped leg means rigidly attached to said inner end of each said handle and pivotably attached to said bin near the rear end of said bin through pivots so that pivotal movement of said handles causes pivotal movement of said eccentric-shaped leg means, said eccentric-shape being in a plane perpendicular to a pivot axis which passes through said pivots; said handles and said eccentric-shaped leg means being pivotable between a first position in which said handles extend in a direction away from said front end of said bin, said eccentric-shaped leg means are in a position to raise said rear end of said bin above the ground, and said wheelbarrow is in a position for transport, and a second position in which said handles extend in a direction towards said front end of said bin, said eccentric-shaped leg means are in a position to lower said rear end of said bin toward the ground, and said wheelbarrow is in a position for loading and unloading; and a roller disposed at said rear end of said bin, said roller supporting said rear end of said bin in rolling contact with the ground when said wheelbarrow is in said second position.
