Product Description
Double Acting High Tonnage Electric Hydraulic Jack
Customization: The color can be customized based on your specific requirements.
The electric hydraulic jack is powered by high-pressure electric oil pumps. It features oil pressure rebound and overflow functions, designed as a safe protection pressurizer to handle emergent overpressure, ensuring safety during construction operations.
Hydraulic jacks can bear partial loading at 5% of rated pressure. The high-pressure alloy cylinder is extremely durable, making it ideal for large-scale projects where easy operation and precise control are essential. Advantages include large output, lightweight design, and remote control compatibility.
