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.
