1.PMG20(D)sideboom is of bulldozer chassis. The counterweight assembly, boom assembly as well as relevant hydraulic/electrical systems are equipped on its platform. It is handle controlled which features simple operation and excellent power performance.
2.The electricity generating function is realized by timing belt transmission device installed between rear output shaft of chassis rear axle box and the generator.
3.Lifting system adopts hydraulic system transmission which is manually controlled, boom and hook's up & down is controlled through 3 handles. Single/double pump oil supplying method makes the hook jiggling (inching) performance better and a wider range for hook speed changes.
