Advantages of excavator telescopic arm
Advantage 1: The external hose pulley separates the hose from the main rope, reducing friction and enhancing maintenance convenience.
Advantage 2: Utilization of a 30mm main rope and a 26mm auxiliary rope, with an upgraded design for smoother pipe stretching.
Advantage 3: Incorporation of an external hose pulley to prevent friction between the main rope and the hose, decreasing failures and easing maintenance.
Advantage 4: Strategic placement of the oil filling hole at the front end of the second arm and refueling holes on both sides of the third arm, enhancing accessibility.
Three-section Telescopic Arm:
- Primary material selection: Q690/HG785 for increased strength and reduced weight.
- Arm tube material: Q690D/HG785 for extended lifespan, reduced weight, and enhanced strength, with Q355B used in another section.
Telescopic Arm Components:
- Integration of nylon material to diminish wear.
- Pulleys crafted from POM material for elevated mechanical strength and rigidity.
- Placement of two sliding wheels at the top and bottom to segregate high and low segments.
- Implementation of pressure hoses and steel wire ropes to minimize friction, thereby prolonging service life.
- Notable segmentation of wire ropes at the top and high-pressure hoses at the bottom, with an adjustable bracket for hose tension adjustments as needed.
