Hydraulic Disassembling Tool Test Outline

GB/T 17906-2021 Fire Emergency Rescue Equipment Hydraulic Demolition Tool General Technology Conditions

GB/T 7999 -2015 Aluminum and Aluminum Alloy Optical Direct Reading Lauding Spectral Analysis Method

Work pressure 73MPa

The maximum opening distance is 52.8mm

Maximum opening of 171kn

The minimum wedge into the gap 3.94mm

Weight: 10. 6kg

Dimensions: length*width*height: 642mm*192mm*l 79mm

After 1.5 times the intensity test of the working pressure of 1.5 times, there is no hydraulic oil sustainable leakage, visible permanent deformation, break or mechanical damage.

After the seal test, the maximum displacement volume is 1.6mm

After testing at a high temperature of 55 ° C and low temperature-30 ° C, it can work normally without leakage and abnormal phenomena.

After the vibration test, the movement is normal and there is no abnormal phenomenon.

The manual replacement valve of the break -breaking tool has the function of automatic reply. During the action, when the hand -controlled direction valve returns to the median, the disassembly tool stops the action within 2S. When the movement is moved again, there is no reverse action.

In the process of action, if the power supply occurs, the sewing device has self -locking performance, and its maximum displacement is 1.6mm.

After the reliability test, the movement is normal, without leakage and abnormal phenomena.
