摘要
The proposed lifting device is formed by two main beams (1), the longitudinal axes of which lie in horizontal plane. The main beams (1) are provided in their end parts with vertical telescopic legs (2.1) consisting of an inner tube (2.4) with transverse through holes. The inner tubes (2.4) are located in a guide strip (2.3) having transverse holes the pitch of which is other than the pitch of the through holes on the inner tube (2.4). The telescopic legs Te (2.1) are further provided with a hydraulic cylinder (2.2). A joint (2.8) possessing capability to swivel only in the direction of the main beam (1) axis is situated between the main beam (1) and said inner tube (2.4) free end.
