Site demolition operations such as building collapse and traffic accidents. Including motorized hydraulic pump, manual hydraulic pump, hydraulic shear, hydraulic spreader, hydraulic shear expander, hydraulic stabilizer, etc., performance meets the requirements of GB/T17906 "General Technical Conditions for Hydraulic Demolition Tools". The motorized hydraulic pump is powered by a small Honda gasoline engine, which is quick to start and has stable performance. All tools have no deformation and damage after 1.3 times pressure test; the cylinder is made of high-strength aviation aluminum, which has the characteristics of high strength and light weight, which effectively reduces the working intensity of firefighters, improves work efficiency, cuts, expands, The performance of the struts is better than the requirements of GB/T17906 "General Technical Conditions for Hydraulic Demolition Tools". Motorized hydraulic pump: rated working pressure 63MPa, high pressure flow 0.4L / min. Hydraulic cutter: The opening distance is 125mm. Hydraulic dilator: expansion force 30KN -45KN, expansion distance 620mm.
