The two counterweight forms have respective advantages and disadvantages, the fixed counterweight has simple structure and is convenient to maintain, but because the counterweight is fixedly connected, the balance moment of a system cannot be changed along with the vertical pitching of a cantilever of a stacker-reclaimer, so that the stress change of a steel wire rope or an oil cylinder driven by a pitching mechanism is large; the counterweight connected by the four connecting rods has a relatively complex structure, is not beneficial to maintenance, and has the advantages that the gravity center of the counterweight can be adjusted within a small range when the cantilever tilts up and down through the connection of the four connecting rod mechanisms, so that the balance moment can be changed within a certain range, but the change amount is very limited.

The counterweight of the stacker-reclaimer is critical to the balance of the stacker-reclaimer, and if the counterweight is too large,

the unbalance moment of the opposite system becomes smaller or is smaller than zero, so that the pitching system is easy to vibrate or overturn (the balance weight falls to the ground); if the balance weight is too small, the unbalanced moment of the opposite system is too large, so that the stress of a pitching driving steel wire rope or an oil cylinder is too large, and the driving extra load is increased.

The existing counterweight form of the stacker-reclaimer cannot realize automatic balance and change moment all the time, cannot enable a pitching driving system of the stacker-reclaimer to be stressed the minimum, and has low safety and stability.
