We can make single-rope two-jaw and four-jaw grab. The single-rope grab is hung directly on the hook of the hoisting mechanism and is a quick-change hoisting device with a simple design and low cost. The peculiarity of the work of these grabs is that the opening / closing process occurs when it touches the surface. With the help of a single-rope grab, it is possible to mechanize loading and unloading operations for the transportation of bulk goods on the existing lifting equipment. The principle of operation of the single-rope grab The open grab moves to the site of soil sampling (pos. A). After touching the ground, the falling lever 1 goes down and captures the axis 2 (pos. B), after which the hook can be lifted. The jaws will begin to close and soil sampling will occur (pos. C). After the jaws are completely closed, the grab can be moved to the unloading point (pos. D). The grab will open after the loaded grab touches the surface, while the falling lever 1 is disengaged from the axis 2 and the grab jaws open under their own weight.
