Abstract: With a view to a quick and safe construction of an elevator using structurally simple and cost-effective means, a method for constructing an elevator in particular, a freight elevator—on a construction site, and preferably in a factory hall. The elevator is built from several components arranged one atop the other. The method includes providing a base for the elevator; positioning a lifting device on the base; raising an upper component of the elevator by way of the lifting device; positioning a lower component, which is to be arranged underneath the upper component, under the raised upper component; lowering the upper component onto the lower component by way of the lifting device; and removing the lifting device from the base. Further specified is an elevator constructed according to said method.

Abstract: In a suspension and guidance mechanism for the filter plates of a filter press, where the dollies (1) that carry filter plates (3), each dolly with two rollers (4, 5) that are staggered with respect to each other in the direction of movement and are positioned on two rails (8, 9), and that move along the rails by a transport device located between the running rollers, the derailment of the dollies is prevented in that, laterally, next to the rollers (5) that move in the direction of transport, there is a guide bar (15) or that these rollers (5) have an enlarged wheel flange (16), whereby the height of the guide bar (15) or of the wheel flange (16) is greater than the lifting movements of the roller (5) away from rail (9), caused by plate adhesion during the acceleration of the dollies.

Abstract: An upright rectangular frame has a roller conveyor in its lower horizontal member, carries hydraulically operated clamps on its upright members, and movably supports a carrier for a tilting circular saw on its upper horizontal member. A panel of plywood and the like can be cut horizontally into two sections while the lower edge of the lower section rests on the roller conveyor and the upper section is clamped to the frame. The lower section may then be shifted horizontally on the roller conveyor in the original plane of the panel and further divided into parts by vertical saw cuts, whereupon the upper panel section is lowered to the roller conveyor, and the procedure is repeated until the panel is entirely divided into portions of desired size.
