Mobile lifting device
First Claim
1. Mobile lifting device comprising:
- a) a supporting carriage;
b) a lifting platform for receiving a load;
c) a hoisting apparatus connected to each of the supporting carriage and the lifting platform, including at least two traction members and, with the aid of which, the lifting platform can be moved with a vertical component of direction in relation to the supporting carriage;
d) a stabilising apparatus which prevents an uncontrolled lateral movement of the lifting platform in relation to the supporting carriage,e) wherein the stabilising apparatus is formed by at least one, essentially rigid pivoting member which is swivellably connected, in one end region, to the supporting carriage and, in an opposed end region, to the lifting platform in such a way that, when the supporting carriage is stationary, a movement of the platform that possesses a vertical component of direction is always linked with a defined horizontal movement of the platform.

Abstract
A mobile lifting device comprises a supporting carriage which is capable of travelling along a specific path and from which there is suspended, via a hoisting apparatus having at least two traction members a lifting platform which can be moved with a vertical component of direction in relation to the supporting carriage. In order to prevent uncontrolled lateral movements of the lifting platform, a stabilizing apparatus is provided which is formed by at least one essentially rigid pivoting member. The latter is swivellably connected, in one end region, to the supporting carriage and, in an opposed end region, to the lifting platform. In this way, a movement of the platform that possesses a vertical component of direction is always linked with a defined horizontal movement. If desired, this defined horizontal movement can be compensated for, wholly or partially, by a corresponding, oppositely directed translational movement of the supporting carriage.
