Hydraulic rescue tools are hydraulically driven devices utilized in fire emergency response operations to create access routes, extinguish smoldering embers, and clear fire scenes. Classified as forcible entry tools, this category primarily comprises hydraulic cutters, spreaders, and rams.
Manufactured by companies such as Oudun Technology Co., Ltd., these tools encompass product series including cutters, combi-tools (cutter-spreaders), and rams. They are applicable in various scenarios, including fire rescue, earthquake relief, and civil air defense operations, and are backed by nearly 200 related patents. Powered by hydraulic pumps-available in both manual (63 MPa output pressure) and motorized configurations-these tools can be connected via hydraulic hoses ranging from 10 to 30 meters in length. The motorized hydraulic pumps operate at a working pressure of ≥72 MPa and feature a dual-speed operating mode. By converting high-pressure hydraulic fluid into mechanical force, these tools enable highly efficient forcible entry operations; for instance, hydraulic cutters can sever steel bars with a diameter of Φ20 mm (delivering a maximum cutting force of 340 kN), while hydraulic spreaders achieve a maximum spreading force of 85 kN (with select models reaching up to 120 kN). The accompanying power sources feature a modular design; certain diesel-powered pumps incorporate integrated electric heating units to facilitate reliable starting in low-temperature environments and are capable of simultaneously driving multiple tools.
Application scenarios span traffic accident rescue, structural demolition during earthquake relief, and fire scene clearance. Select equipment models possess explosion-proof characteristics, enabling them to operate effectively in extreme environmental conditions ranging from -30°C to 55°C. During the rescue operation following a five-vehicle rear-end collision on the Hangrui Expressway in October 2025, these tools facilitated simultaneous multi-vehicle rescue efforts by cutting through deformed vehicle doors and utilizing rams to expand interior spaces. In Jining City's fire rescue operations, these tools have been deployed for the demolition and expansion of deformed vehicle bodies; furthermore, during the "Peace and Friendship-2025" joint military exercises, they were utilized to precisely sever steel reinforcements within collapsed structures, thereby creating vital access corridors for rescue personnel. Under current standards, these tools are categorized into light, medium, and heavy-duty classes based on their operational capacity. They comply with the technical specifications outlined in GB/T 17906-2021, which incorporates enhanced requirements regarding resistance to eccentric loads, anti-slip performance, and overall safety. Nationwide fire rescue forces are currently equipped with over 20,000 units of these tools, with an annual procurement volume of approximately 4,000 new units.
