FIELD: construction.
SUBSTANCE: invention relates to the construction, namely is associated with used in the materials driving and extracting gripping device, called grooved piles, shapes and steel pipes. Gripping device used in driving and extracting steel materials, in particular grooved piles, shapes and steel pipes, in general, includes at least one gripping mechanism, enclosing and holding steel material, in particular, grooved piles, shapes and steel pipes, as well as ensuring the said material installation at the required angle during driving and extraction. At least two gripping elements located on both sides of the gripping mechanism, which hold the gripping part, performing the synchronous operation. At least one hole, located near the gripping mechanism center, and intended for the gripping element attachment to the gripping mechanism. At least one thrust ring, located in the hole and providing the gripping element rotation around this hole central axis. Gear wheel located near the hole, a gear wheel ensuring the gripping elements synchronous operation, as well as the compressive force even distribution. At least one lining, providing the gripping elements full adhesion to the material to be captured. At least one actuator, mounted on the gripping elements one end, and ensuring the gripping elements synchronous movement as the result of pressure application to them.
EFFECT: technical result consists in ensuring the capture of the driven element of any size, improving the driving quality and efficiency.
