Mechanical handling apparatus includes a surface and a driving mechanism for moving a load over the surface which comprises a substantially vertically reciprocable platform device for actuating the load, and a lever device including at least two oppositely pivoted levers for raising and lowering the platform device. Preferably, the apparatus comprises a platform for carrying loads, a mechanism for raising and lowering the platform, the mechanism including at least two levers each pivoted relative to the platform and each pivoted relative to a respective one of a pair of actuating members, the actuating members being movable towards and away from each other, whereby relative movement of the actuating members in one direction pivots the levers to raise the platform and relative movement of the actuating members in the opposite direction pivots the levers to lower the platform. |
