| description | FIELD: materials handling facilities; load lifting cranes. SUBSTANCE: seat of operator installed in load lifting crane cabin has flat-lever motion consisting of two parallel four-member parallelograms formed by hinge-connected members. Axle passes through middle of lower member of one of parallelograms. Hollow lever with fitted-on spring-loaded lock is secured on axle. Locking member of lock can occupy one of three positions in slots of worm wheel installed on axle which makes it possible to adjust position of seat for "operation with tilting", "operation without tilting" and "rest", discretely. To provide stepless adjustment of seat position, worm wheel is provided. Worm wheel engages with worm controlled by handwheel secured on horizontal axle. Two of four - member parallelograms and worm pair are mounted on frame installed in vertical upright connected with cabin floor through vibration protection torus-shaped member to reduce vibrations transmitted to operator through seat. EFFECT: enhanced conditions of operation owing to provision of three different positions of seat. 2 dwg |
