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

Lubrication system for sliders help support butter easily.
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.
