Adjustable retainers with possibility to limit rollers travel and possibility to limit eyes approaching each other in upper (vertical) position are installed in horizontal slots of base platform. On top surface of base platform, spring-loaded vertical rod is installed kinematically linked with another vertical rod, and through it - with eyes position indicators. In the central part of base platform, four rods are mounted which limit crane hook location both in work position and when crane hook is turned through 90. Compensator is made as sleeve which inner diameter is made with possibility to use it both as support and as guide for top part of spring guiding rod. ^ EFFECT: increase of reliability; increase of durability; widening of processing capabilities and occupational safety assurance. ^ 3 cl, 3 dwg
