Spring balancer tower elastic self-locking tension balance crane self-locking thruster balance crane

1. When selecting the spring balancer [1], in addition to the weight of suspended tools, the weight of other auxiliary equipment shall also be considered.
2. Hang the balancer hook at the fixed point or movable point above the work post, and fasten the safety rope or safety chain to ensure absolute safety in use.
3. The balancer should be used within the specified balance weight range, otherwise it will affect normal use.
4. Before removing the tool from the balancer, rotate the worm counterclockwise to release the spring force, then pull out the stop pin rod, rotate it clockwise by 30 °, put it into the groove, lock the tower wheel, fix the lower end on the welding tongs hook or other reliable objects with ropes, and then remove the tool to prevent the hook from quickly retracting injury or tool damage after sudden unloading.
5. The balancer shall not pull out all the steel wire rope during use, otherwise it will cause premature fatigue fracture of the steel wire rope at the root of the tower pulley, and the steel wire rope shall be kept at least more than two-thirds of the circle in the tower pulley, so as to avoid the fracture of the steel wire rope at the root of the tower pulley.
6. The most ideal use state of the balancer is that the steel wire rope moves in the middle section of the tower pulley, which can effectively avoid the mutual wear of the steel wire rope and the tower pulley and prolong the service life of the balancer.
7. Do not disassemble or repair the balancer unless directed by a professional.
