ZHONGHE 3 section telescopic arm with clamshell bucket, which usually load trucks with materials excavated from deep space underground.

1.The external pulley separates hoses from ropes, avoids friction.
2.The sliding blocks can be replaced quickly.
3.Grease filling holes for centralized lubrication
4.Upgrated 30mm main ropes and 20mm vice-rope help stretching smoothly.
5.A high quality clamshell bucket is in the plan.

A selection of excavator Tele dipper arms with hydraulic Clamshell Bucket or Grapple have been developed for common projects which include:

• Foundation work
• Narrow excavation shafts
• Metro station
• Underground parking and renovation and canal clearance
• Deep excavation projects for contractors, shoring
• Construction companies that use braced excavation
• Diaphragm walls

Whether it be above ground, underground or underwater, these custom telescopic dipper arms can reach down to 140 foot depths at 90-degrees with a rotating hydraulic attachment on a suitably sized excavator.

(Robust structure)
1. The box is made of LG700 high strength material, LG900 is optional
2. Bearing part with multi-layer reinforced

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

(Long service life)
1. The reel adopts enlarged spring piece
2. Adopt Strong bucket cylinder

(Avoid oil leakage)
1. Hydraulic hoses are made of four-layer steel wire ring.
2. The telescopic cylinder adopts double oil seals
3. Bucket cylinder hose was built-in to avoids oil leakage caused by hose vibration

(Easy to maintain)
1. Lubrication system for sliders help support butter easily.
2. 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

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. The telescopic function of the telescopic arm is controlled by the original breaker pipe. 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.
