Abstract

The invention relates to a gripping mechanism and a method by means of such a gripping mechanism, comprising a carrier, at least two longitudinal members (2, 3; 102, 103; 202, 203) parallel to each other, and at least two transverse webs (4, 5; 104, 105; 204, 205), which form the carrier, a gripping means (19, 20), which is borne by the carrier and which picks up the products (21) to be conveyed, a connecting device (13; 111; 219), and a lifting device, wherein the gripping means is formed by a continuous, flexible element (19, 20), which hangs down in the manner of a loop by with ends arranged at a distance from each other and is formed by at least one transverse web and can be lengthened and shortened by means of at least one rewinding device (8; 120; 215) that can be actuated. According to the invention, the at least one transverse web (6, 7; 104, 105; 204, 205) bearing the rewinding device (8; 120; 215) can be moved along the longitudinal members and can be actuated by a drive, wherein the position of the transverse web can be determined by means of a scale bar on the longitudinal member and correct balancing of the freight is enabled.

description

The present invention relates to a gripping mechanism for elevators according to the preamble of patent claim 1.

Known elevators are, except with hooks, provided with straps which are around the promotional

Product around U-shaped or schlingenart ig to tighten or tighten. The belt lengths are fixed and the cargo is often not all easy to balance with the risk that one or more of the cargo loose and fall to the ground. If, on the other hand, the belts are displaced, the endangerment of the product to be conveyed is endangered. So are with the known technology the

appropriate gripping organs neither able to position the product to be promoted nor to ensure the integrity of the product nor to avoid any danger to the integrity of the operating personnel.

Well-known methods for realigning piece goods during a production run and positioning them precisely are always carried out with the help of additional manpower Reorient cables. As a result, these persons are exposed to a great security risk, since they must always be in the immediate area of action of the lifting device. Greatest danger for the assistants

Workers arise when the upscale

Loads vibrate and thereby forces arise, which are no longer controllable by male powers.

This object is achieved by a Gr e i fme chani smus for hoists according to the ken signing part of claim 1.

Under the proposal of a G reim c ha ni smu s, which includes a frame which constitutes a gripping organ for To accommodate products to be conveyed, and includes a combination of frame and hoist, the gripping member may be formed by at least one continuous, flexible element, which may also be typhoidal
