ABSTRACT

The present application relates to the aerial work platform field, disclosing
an electric-driven aerial work platform and a hydraulic system thereof. The
hydraulic system includes a superstructure hydraulic system and a substructure
hydraulic system. The superstructure system includes a luffing cylinder, a
telescopic cylinder, and a superstructure hydraulic pump supplying oil to the
two cylinders. The substructure system includes a steering cylinder, a
floating cylinder assembly, and a substructure hydraulic pump supplying oil to
the steering cylinder and the assembly. The superstructure and substructure
systems are independent, with the superstructure pump having a greater rated
displacement than the substructure pump. This independent and distributed
arrangement overcomes the problem in the prior art, where high-pressure oil
from the superstructure hydraulic pump must be transported through the central
rotary joint, causing significant pressure loss. The system can save energy,
increase efficiency, and achieve emission reduction.
