Advantage 1: The external hose pulley separates the hose from the main rope, avoiding friction between the main rope and the hose, reducing failures and making maintenance more convenient.
Advantage 2: Using 30mm main rope. Use 26mm auxiliary rope.
Upgraded auxiliary rope design to make pipe stretching smoother
Advantage 3: The external hose pulley separates the hose from the main rope, avoiding friction between the main rope and the hose, reducing failures and making maintenance more convenient.
Advantage 4: The oil filling hole is at the front end of the second arm (to the upper slider).
The refueling holes are located on both sides of the front end of the third arm (to the top slider)
Three-section telescopic arm
The main material we choose is Q690/HG785
lighter and stronger
The main material of the arm tube we use is Q690D/HG785
Extended life, lighter, stronger
Another place we use Q355B.
telescopic arm
Nylon material to reduce wear
Our pulleys are made of POM material, which has high mechanical strength and rigidity.
Two sliding wheels are at the top and two others at the bottom, this part separates the high and low parts.
The pressure hose and steel wire rope reduce mutual friction. Less friction can extend the service life. You can see the top is the wire rope and the bottom is the high pressure hose on either side. Additionally, there is an adjustable bracket here to tighten the hose as needed.
