The safety of the three-stage blasting arm is better than that of the ordinary standard blasting arm. The middle boom increases the safe distance between the cockpit and the working parts. Safety operation is strongly advocated at present, and three-stage blasting will be the development trend in the future.
The demolition arm is used for the reconstruction of old houses and old cities, urban demolition projects, chimney demolition, etc.

Material: plate Q355B (optional Q690D), hydraulic steel pipe is cold-drawn seamless steel pipe, pin material is 40Cr, high-pressure rubber hose is 4-layer steel wire joint venture pipe, butter hose is single-layer rubber hose, and the bushing of the boom seat is graphite alloy Copper sets.
Structure: 1 boom, 1 middle arm, 1 small arm, 8 pin shafts, 12 stop valves, 1 bucket oil cylinder (20t level), all high-pressure hoses, and 1 set of linkage devices.
Product advantages: The large and medium-sized booms designed by our company are reasonable in size. After dismantling the arm and installing the breaker, it can rotate normally. The large and medium-sized arms can achieve a 180-degree opening angle, and the overall disassembly height will be higher. The overall production technology is ahead of the industry average, and the product quality is better than products of the same level.
