Equipment Features:

1. Compact structure, stable operation, large operating space, and no need for a crane. The test bench adopts computer automatic control, with functions such as measurement, recording, and printing, enabling the detection of free height, working height, spring stiffness, and static deflection of vehicle coupler coil springs.

2. Static pressure test for elastic rubber buffer, static pressure test for hydraulic buffer, and pre-compression measurement for buffers with pre-shortening function before installation.

3. High degree of automation, simple operation, very suitable for on-site use. Additionally, this testing machine can also serve as an auxiliary tool for spring disassembly and assembly.
