Abstract

The present invention relates to a lifting apparatus, especially a barrel tilter, which is preferably raisable and movable by means of a low lift truck (4). To eliminate the need for power units in each of the lifting apparatuses, the lifting apparatus (1, 37, 45, 50) comprises a base member (2) onto which a low lift truck (4), preferably a lift truck by means of which the lifting apparatus is raisable and movable, can be driven to weight the base member (2) from above, and a lifting unit (3) movably connected to the base member (2) is so arranged in relation to the base member (2) that the parts of the truck (4) which are to perform lifting are positioned beneath the lifting unit (3) when the truck (4) has been driven onto the base member (2), whereby the lifting unit (3) can be operated by the parts of the truck (4) adapted to perform lifting to impart lifting movements to the lifting unit (3) while the base member (2) is weighted by the truck (4).

Claims9

Dependent claims

A lifting apparatus operable by a lift truck provided with a lift fork movably mounted on lift means, wheel means and a power unit, which lifting apparatus comprises:

(a) a base member;
(b) a lifting unit connected by means of pivotal linkage means to the base member and movable relative thereto:
(c) the base member including means for selective engagement by the wheel means of the lift truck;
(d) the lifting unit including means engageable by the lift fork of the lift truck;
and
(e) wherein when the wheel means of the lift truck are in overlying engagement with the base member, the lift fork of the lift truck may impart a lifting movement to the lifting unit while the base member resting on a support surface remains in a stationary position on said support surface, and when the wheel means of the lift truck are not in engagement with the base member and the lift fork changes lateral position relative to the engageable means of the lifting unit, the lift fork of the lift truck may lift both the lifting unit and the base member from said support surface.
