Abstract: The invention relates to a carrier system for a trackable solar energy plant, in particular a ground supported solar energy system, comprising a support system and a solar module retainer, which is configured to receive a plurality of solar energy modules in a flat arrangement for the automatic tracking around a swivelling axis between settings, installed pivoting on the support system, where the solar energy module retainer is received at support points of the support system resting at the base on a respective three-point arrangement of bearings by means of allocated support elements.

Abstract: The invention concerns a scissors-type elevating platform, comprising two pairs of scissors, spaced apart in parallel and arranged between a base unit (20) and a support unit (10) moving up and down. Said pairs of scissors have each two scissors arms (1, 2) pivotable relative to each other about a scissors axle (9). Said device also comprises an elevating mechanism having at least one spreader unit (4) which can reciprocate between the scissors arms (1, 2) to raise and lower the support unit and which is coupled to a winding shaft (12) via a traction element assembly (5) capable of being wound on the winding shaft (12) driven by a motor, said traction element assembly comprising at least two flat traction bands spaced apart in parallel. The width of the traction bands is selected so as to ensure, when the support unit (10) is raised, that the bands are superimposed on the winding shaft.

Abstract: The invention relates to a scissors-like lifting device having a pair of scissors that are arranged between a carrier or support unit and a base unit. Each pair of scissors is provided with two arms which can be pivoted about corresponding axles. The scissors-like lifting device is provided with a lifting truck that can be moved by means of a drive in order to open and close the scissors. The inventive configuration efficiently controls the lifting movement. The band-like traction mechanism can be wound-up on the drum by means of the drive in order to pull the lifting truck towards the scissors axle so that the scissors are opened. The band-like traction device can be unwound from the drum so that the truck is moved away from the scissors axle by the force of gravity on the support and arms thereby closing the scissors.

Abstract: The disclosure relates to a scissors lifting device having a pair of scissors positioned between a carrier unit and a base unit. The scissors have inner arms and outer arms which can pivot in relation to each other about a scissors axle. The lifting device further includes a lifting truck that can be moved back and forth by means of a drive in order to open and close the scissors. According to the invention, a drive shaft that is oriented parallel to the scissors axle is coupled to the drive and enables at least one traction mechanism that is arranged around the drive shaft and is coupled to the lifting truck to be moved in both directions of rotation. This results in a construction having a reliable drive.
