Description

Technical Field

[0002] Hydraulic-electric outriggers combine hydraulic and electric drive technology, primarily used on vehicles such as semi-trailers, cranes, and construction vehicles to provide stable support and leveling. These outriggers utilize an electric motor to drive a hydraulic pump, which in turn propels the hydraulic oil, driving the hydraulic cylinder to extend and retract, extending and retracting the outriggers and raising and lowering the load for stable support. Many different models and specifications of hydraulic-electric outriggers are available on the market, and the appropriate model can be selected based on specific application requirements (such as load capacity and operating environment).

When encountering inclined surfaces, the contact area between the ground surface and the ground is small, and the support effect provided is poor. Therefore, a hydraulic and electric-driven outrigger is proposed to solve the above problems. Utility Model Content
