Hydraulic Support Column Jack Test Bench
AI-Driven Automation – Reduces human error with computer-controlled precision.
Dual-Pressure Flexibility – Combines low-pressure emulsion + high-pressure oil for diverse tests.
Industry-Leading Accuracy – 0.5-class sensors ensure reliable compliance data.
Heavy-Duty Loading Frame – Supports 8,000 kN for extreme-condition testing.
One-Click Reporting – Automated data storage and export streamlines documentation.
LZQ-3C Hydraulic Support Column & Jack Test Bench (Computer-Controlled)
Developed through extensive research across China's coal mines and analysis of global test bench designs, the LZQ-3C is an advanced automated test bench for hydraulic support columns and jacks. It performs factory acceptance tests (FAT) and pressure-sealing inspections when paired with a horizontal press, making it ideal for mining hydraulic maintenance and quality control.
Compliant Standards:
GB/T 25974.2-2010 (Hydraulic Supports for Coal Mines – Part 2: Columns & Jacks)
MT 313-1992 (Technical Conditions for Hydraulic Support Columns)
Key Features
✅ Fully Automated Testing – Computer-controlled operation after manual parameter input.
✅ Smart Process Switching – Seamless transition between test phases; uses external emulsion pump for initial support.
✅ High-Precision Sensors – 0.5-grade accuracy meets industry standards.
✅ Auto Report Generation – Stores test data and generates printable reports.
✅ Dual-Pressure System – Low-pressure emulsion pump + oil-driven for variable test pressures.
✅ Enhanced Flow Rate – Upgraded hydraulics boost filling efficiency for columns.
✅ User-Friendly Design – Centralized button panel & built-in lighting for ease of use.
