Hydraulic dismantling tool group, fire rescue support, top spreader, shear expander, expander

The dual output hydraulic dismantling tool set is the core equipment for dealing with complex dismantling scenarios in fire emergency rescue. It consists of hydraulic mobile pumps, shears, expanders, and supports, and has the characteristics of efficient dismantling and precise rescue.

Application scenarios and operational standards

1. Typical rescue scenario

• traffic accidentThe shear expander cuts off the deformed frame, the expansion expander opens and squeezes the car door, and the top support stabilizes the vehicle to prevent rollover.

• Building collapseThe top support device supports the floor slab to form a rescue passage, and the shear expander removes reinforced concrete obstacles.

• fire sceneHydraulic door opener can break down the anti-theft iron door within 5 seconds, and the expander opens the ventilation opening to accelerate smoke exhaust.

2. Key points of operation and maintenance

• Quick Deployment：

• The starting time of the hydraulic pump is ≤ 10 seconds, and the tool connection uses Kevlar fiber high-pressure hose (pressure ≥ 35MPa), which rotates 360 ° without knotting.

• When two people cooperate, the pump operator can remotely control the tool movement through a wireless remote control (30 meters away).

• preventive maintenance：

• Hydraulic oil should be replaced every 200 hours or six months, and ultrasonic cleaning machines should be used to remove impurities from the filter element.

• Polish the cutting edge with oilstone every week to maintain a 30 ° cutting angle, and inject lithium based grease into the hinge point of the expansion arm.

• safety regulations：

• During homework, keep the tool perpendicular to the fulcrum and avoid lateral forces exceeding 30% of the rated value.

• High pressure hoses undergo burst testing every quarter, and if bulges or exposed steel wires are found, they should be replaced immediately.
