SUNWARD SWE235ES Crawler Excavator

▲ Hydraulic hybrid power system

Invented a self-balancing accumulator and multi-cylinder pressurized energy-saving method to recover and utilize the potential energy of the boom, and invented a new self-balancing boom structure with multiple hydraulic cylinders, which solves the problem of high-pressure and large-capacity hydraulic pressure for medium and large excavators. The problem of energy storage recycling. The energy saving effect reaches more than 30%.

▲ Series bucket

The series of buckets with multiple functions and different capacities under the same tonnage are available for customers to choose. The maximum bucket capacity can be increased by more than 30%. Each bucket has more earthwork and creates greater value.

▲ Self-matching technology of rotary flow

Invented a self-matching slewing energy-saving method of flow. Based on the system pressure change during the compound action of the excavator, the system state is automatically identified through a multi-source energy decoupling control algorithm to realize the on-demand distribution of slewing flow. The problem of large overflow loss when the excavator is slewing is solved, and the overflow is reduced by 95%.

▲ Boom energy saving valve

Invented an energy-saving valve block capable of pressurized energy recovery and utilization, which realizes the low-cost and high-efficiency recovery and reuse of the potential energy of construction machinery.
