1. The telescopic arm is BS900 material, lighter and stronger. with much deeper excavation depth, simple and convenient operation, safe and reliable.

Lighter and Durable of telescopic boom

1.The external hose pulley separates the hose from the main rope, avoids the friction between the main rope and the hose, reduces failures, and makes maintenance more convenient

Rope Structure

1. Adopt 30mm main rope

2. The upgraded auxiliary rope design makes the pipeline smoother while stretching

3. Adopt 26mm auxiliary rope

Easy To Oil Filling of excavator telescopic arm dipper stick 28m

1.Oil filling hole at the second arm front end(to the top slider)

2.Oil filling hole position on both sides of the third arm front end(to the top slider)

Wire Rope of Telescopic Boom

The inner core of the steel wire rope is a steel core with higher tensile strength. The brand chooses Xianyang Gemstone, which is a torsion-resistant steel wire rope specially used for rotary drilling.
Using a 30mm main rope, it can carry greater pulling force and impact force, making it safer and more durable.
The bearings are selected to be larger than those on the market, which can carry greater pulling force and impact force.
The processing technology uses better welding wire and better processing technology to ensure the accuracy of the arm tube. The refinement of the assembly process and the refinement of details make maintenance more convenient.
The pulleys are made of Sai Steel material, and enlarging the pulleys can carry greater pulling force;

Separation of hose and wire rope of clamshell telescopic arm
 

Easy to replace hose. Convenient to replace the wire rope.

The hose is placed on the side, and the hose is basically not squeezed by the arm, reducing pipeline wear and pipe bursting problems.

Q1. What is the length of the telescopic boom? Is it the total length of the boom?
A1. The length of the two-stage telescopic boom refers to the excavation depth. For example, the 14m telescopic boom refers to the maximum excavation depth of 14m, not the boom length of 14m.

Q2. How to judge the length of telescopic boom that can be made for different models?
A2. Because the length of the telescopic boom is directly related to the length of the boom. We should ensure that the telescopic boom will not touch the bridge when it is placed on the ground.

Q3. Do I need to modify the original machine when installing the telescopic boom? Are there any precautions?
A3. The original machine needs three sets of pipes. We need to replace the original one-way foot switch with a two-way foot switch to achieve the telescopic function. The other operations are the same. The more important thing is balance and safety. Try to avoid the 90 degree operation between the cab and the track shoe.

Q4. Note and maintenance of telescopic arm
A4. 1st, telescopic arm does not allow inclined excavation. 2nd, it can't dig hard things but only soft soil. 3rd, it is not allowed to jack or hoist when the smallest arm is not fully retracted. 4th, the end can't lift things more than 1 ton, which are easy to bend the telescopic arm. If so, no warranty. 5th, telescopic boom shall be greased every day, and the boom barrel shall be greased at least once a week to keep the boom barrel full of butter.
