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

Materials: Sheet material is Q355B(Q690D is optional), hydraulic steel pipe
is cold-drawn seamless steel pipe, pin material is 40Cr, high
pressure hose is joint venture pipe with 4 layers of coil wire,
shea tube is single layer hose, and the bushing of big arm base is
graphite alloy copper sleeve.
Structure: 1 boom, 1 middle arm, 1 arm, 8 pins, 12 globe valves, 1 bucket
cylinder (20t class), all high-pressure hoses, 1 set of linkage
device.
Product advantage: The size of large and medium-sized arm designed by our company is
reasonable. After the dismantling arm is installed with the
crushing hammer, it can rotate normally. The large and medium-sized
arm can realize 180 degrees of opening Angle, and the overall
dismantling height will be higher. The overall production
technology is ahead of the average level of the industry, and the
product quality is better than that of the same level.
Advantages of long reach demolition for excavator
1. Applicable for all the make and model of the excavator.
2. Many different materials such as Q345B, and Q690D are optional
to suit your application.
3. Big boom can be two jointed pcs to make it fittable into a
container to save shipping costs.

self-lubricating carbon powder inside to extend the life of the
long arm).
