Patent DE-3804193-A1 (DE)
Title: Process, apparatuses and devices for telescopic masts of mobile and stationary lifting gear
Inventor: VOGEL RUDOLF DR ING
IPC: E04H12/18
Filed: 1988-02-11
Abstract: Experiences shown that the known telescopic masts, such as hydraulic multiple housing telescoping units, have, in dependence on systems, very limited lifting heights and a high dead weight with a relatively low degree of bending rigidity. The mast according to the invention is wound in the manner of a three-dimensional spiral from a high-strength band which continues in one piece, the load-bearing capacity of said mast not being impaired by the wound assembly, as a result of which unconventionally large ratios of mast diameter to band thickness and very large mast diameters and thus a very high degree of rigidity with correspondingly large lifting heights, along with an extremely lightweight construction, can be achieved. The band is accommodated in a compact manner in a store, which encases the mast closely, and, held in a slip-free manner by a pressure-exerting roller, passes at the transition point from the store into the mast. The positively locking, releasable connection of the mast windings bears the loading of the mast and, via this, the mast, which is smooth on the outside, is telescoped by a conventional rotary drive. The unconventional mast structure is secured by a series of means according to the invention.   <IMAGE>
