1. This testing machine with integrated steel plate welded frame structure, using single boom and double-function
piston liner to load testing force and fixing specimen with cylindrical pin, load cell measuring force, several
regulation grades of testing space according to length of specimen.
2. Computer control and display testing force & testing curve and process test data automatically as settled
3. This machine is specially used in one by one test for products like lifting straps, chains and ropes as it
operates easily, and uploads slowing and steady and with strong bearing capacity.
Main structure introduction:
1. Host System (as graph 1)
Host machine consists of hydro-cylinder stand, hydro-cylinder piston, shifting cross-beam, fixed cross-beam
and load cell.
2. Hydraulic power system:
Hydraulic power system is comprised of four parts: Oil pump generator system, electric system, piping system
and oil tank (including valve bank and supporting facility).
3. Controlling, measuring and display system:
3.1. Adopt hydraulic testing machine specially used proportion servo valve to control load of test force, operate
3.2. Computer controls load keeping of test force.
3.3. Precision Load cell measures test force.
3.4. Computer screen displays test data, drawing test force VS time, force VS displacement curves, curves
automatically switches to data for process.
3.5. Have whole file operation and data reserving functions, test data is finished in ASCIIcode format, easy for
secondary digital process.
3.6. Test report can be printed.
3.7. Have completed safty protaction device.
3.8. When test force over 2%-5% of maximal test force of each grade, overload protection automatically turn on,
3.9. When displacement of piston reaches limit, stroke protects, oil pump generator stops.
1. Host machine
1.1. Rack use integrated steel plate welded frame structure; Main structure is comprised of front and back Clamp,
oil tank and front beam.
1.2. Manually push back clamp stand to regulate testing space
1.3. Outline is designed as requirement of horizontal testing equipment; Make the machine be steady, safe and
2. Loading structure: 500/1000/2000/3000KN Hydraulic Pump loading
2.1. Single action piston and double-direction structure is made as precise processing technique.
2.2. Adopt imported SPGO-HBTS seal component to ensure low damp between piston and cylinder.
2.3. Use load cell measure axial test force, have high precise displacement measurement with encoder.
2.4. The top of piston rod installed ball and socket bearing and flange plate connect it with load cell.
3. Back clamp stand displacement measure device
3.1. Back clamp stand is pushed manually to regulate testing space easily.
3.2. Displacement of back grip stand is driven by movement of sustain dolly at lead rail.
3.3. Testing space range: 500~6000mm.
4. Hydraulic pump pacakge
4.1. One set 10L/min, 30Mpa constant pressure pump.
1)used in 2000kN loading system
2)use well-known brand motor, imported low noise, high pressure gear pump.
4.2. Motor is equipped with vibration damper (vibration reduction pad) to reduce vibration and noise.
4.3. Oil tank: Whole sealing standard oil tank, 80L with oil temperature gauge, oil level indicator, precise press
filter and gas filter, additionally have oil temperature, oil level and oil resistance protection and indication
device. Oil filter also can be equipped as requirement of real condition.
4.4. Strong current controlling system: Operation and control console use desk structure, placed in testing and
operating area, have special operation panel make operation easily. It will stop automatically or alarm for
over-limit oil temperature, filter blocked and over-low oil level.
4.5. Pipeline system: Master cylinder loading, hydraulic pipeline of grip actuator is connected with high-pressure
