The invention relates to a lifting device, especially a mobile lifting device, for lifting loads, vehicles or the like, said lifting device comprising a lifting column (14), a support (21) which is guided by the lifting column (14) and on which a load carrying means (22) can be arranged, and a drive unit (18) which can be controlled via a control unit (17) and which moves the support (21) up and down in relation to the lifting column (14). The support (21) has a sleeve-type or bullet-type shape and surrounds at least part of the lifting column (14).

A three-level vehicle lift. The lift includes a four-post configuration in which each post includes a pair of vertically extending, side-by-side channels. Two platforms are provided. Each includes a carriage configured to engage a respective one of the channels in each post and a hydraulic actuator and lifting cable system disposed within the platform for lifting the platform. An actuation system having a single hydraulic pump is provided with a valve for selectively supplying hydraulic power to either an upper- or a lower-platform hydraulic circuit. The simplified lift and actuation system configuration reduces manufacturing, shipping, installation, and materials costs and complexities.

An apparatus for hoisting and forwarding of logs enables the forwarding of logs along an axis towards a processing area. The apparatus is adjustable in height either due to various configuration of ground or to various heights of processing area in various wood processing machines, and is comfortable both for each user as well as for manufacturers and distributors. The apparatus is also easy to transport to any desired locations by means of a tractor. To this aim, supporting legs on the apparatus are telescopic and connected a bearing framework, with a movable part engaging the ground. Bearing members on a hoisting unit are telescopic and embedded in the bearing framework, with a displaceable part (engaging the ground. The bearing framework may be provided on its side and faced away from the hoisting unit, as well as furnished with a coupling member for connecting the apparatus to a tractor.

A portable lifting apparatus is provided. The apparatus has a modular frame comprising a first frame member and a second frame member, which in combination support a load-bearing beam having a lifting device secured thereto above a lifting surface. The first frame member, the second frame member, and the lifting device are each removably secured to the beam such that the apparatus may be disassembled into constituent components for transport or storage. Each frame member may be configured to disassemble into constituent components comprising a base and two or more support rails. The apparatus may further comprise a counterbalance. The counterbalance may serve to balance load distribution when the apparatus in use and act as a storage receptacle for the first and second frame members, the beam, and the lifting device when the apparatus is disassembled.
