GYJK-38-60/33(25) 72Mpa Single Tube Hydraulic Combi-tool
GYJK-38-60/33(25) 72Mpa Single Tube Hydraulic Combi-tool
I. Product Overview
The hydraulic cutter spreader is an efficient hydraulic demolition tool designed based on human mechanics. This product adopts a single-tube single-interface design without a tail pipe, allowing for operation under pressure. It can be operated in one press, making the operation convenient and simple. Controlled by a non-slip switch, it can accurately perform operations such as cutting and clamping. A two-way hydraulic lock is used inside, which has the function of self-locking and pressure maintaining. The handle is equipped with an integrated LED lighting system, which can provide long-lasting lighting for rescue workers. The 360° rotating mechanical handle design enables multi-angle cutting operations, making the operation convenient. At the same time, it also has the characteristics of light weight, good flexibility, strong functionality, balanced body, labor-saving, and easy operation. The cutter spreader integrates the functional features of a spreader and a cutter on a single rescue device, so it can be the first choice for emergency rescue tools.
II. Product Features
- The hydraulic cutter spreader has the functions of cutting, spreading, and pulling simultaneously.
- It can disassemble the whole vehicle and cut off vehicle components, metal structure pipelines, special-shaped steel bars, and steel plates.
- The cutting tools are made of regrindable high-strength alloy tool steel, with a long operation time and good wear resistance.
- The moving parts are equipped with protective covers. The cutting is splash-proof, and the automatically resetting manual control directional valve provides safety guarantees for the operator.
- The operation of the manual control valve can fix the opening and closing of the blades at any position, and it can be self-locked.
- The opening and closing time is short, accelerating the rescue process.
- All the sealing parts are imported, with better quality.
- The design without a tail pipe makes it convenient to carry, store, and operate.
- The tool adopts a single-tube single-interface design, which can be quickly connected, plugged and unplugged under pressure, making the operation safer and more convenient.
- The large opening distance enables it to handle most rescue situations. The integrated design of the handle and the switch greatly facilitates the operation of rescue workers.
- The newly designed bolt inlay structure is easier to use in a narrow space.
- The equipment is designed with an “acceleration valve”, which increases the speed by 65% compared with traditional technology, speeding up the rescue progress.
- The detachable cutter spreader head can be quickly replaced, making it convenient to expand other functional cutter spreader heads.

Testing basis:
Test Outline for Hydraulic Demolition Tools GB/T 17906-2021 General Technical Conditions for Hydraulic Demolition Tools of Fire Emergency Rescue Equipment GB/T 7999-2015 Method for Optical Emission Spectrometric Analysis of Aluminium and Aluminium Alloys by Direct Reading
Operating pressure: 75MPa
Expansion force: 59.6kN Expansion distance: 370mm Shearing capacity: Capable of cutting a round steel with a diameter of 30mm (made of Q235A material) at one time. No-load closing and opening time: 9.2s Mass: 13.7kg External dimensions: Length * Width * Height: 839mm * 267mm * 212mm
After the demolition tool undergoes a strength test at 1.5 times the rated operating pressure, there should be no persistent hydraulic oil leakage, visible permanent deformation, fracture, or mechanical damage.
After the sealing test, the maximum displacement is 1mm. After the tests at a high temperature of 55℃ and a low temperature of -30℃, it can work normally without leakage or abnormal phenomena. After the vibration test, the operation is normal without abnormal phenomena. The manual directional valve of the demolition tool has the function of automatically returning to the neutral position. During the operation process, when the manual control directional valve returns to the neutral position, the demolition tool stops operating within 2s. When it operates again, the demolition tool does not move in the reverse direction. During the operation process, if the power supply is interrupted, the cutter spreader has a self-locking performance, and its maximum displacement should be 1.4mm. After the reliability test, the operation should be normal without leakage or abnormal phenomena. There should be no curling or chipping of the cutting edges of the cutter spreader.
