1.Durability: Telescopic arms are designed to withstand the stresses and strains of heavy-duty excavating work.
They are made from high-strength steel or other durable materials.The box is made of LG700 high strength material. Bearing part with multi-layer reinforced.
2.Telescopic Functionality: A telescopic arm can extend or retract to increase or decrease the reach of the excavator. This allows operators to work in a wider range of environments and reach deeper into excavation sites.
3. The reel adopts enlarged spring piece
4. The pivot end is reinforced with multiple layers to withstand greater excavation forces
5. The exposed bucket cylinder can be replaced without disassembling arm, which is convenient for
maintenance
6. Four-layer steel wire high pressure hose, more durable
7. The telescopic cylinder adopts double oil seals, and the built-in slider reduces the vibration of the cylinder, avoids sagging due to gravity, improves the service life of the cylinder and reduces failures
8. Bucket cylinder hose design avoids oil leakage caused by hose vibration, and the hose can be replaced without dismantling the arm, improving its service life

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.
