Our telescopic arm have 3 advantage

01 design advantage , there are four sliding wheels on the front,Two sliding wheels on the top , the others two on the bottom , this part separate the high pressure hose and the steel rope , to reduce grinding each other ,less grinding can prolong the service life .

02 The part advantage, the vice rope diameter is 26 millimeter , the main rope is more stronger , you can see is 30 millimeter.the sliding block, it is nylon material , it can reduce grinding,Our sliding wheel is POM Material , with high mechanical strength and rigidity

03 easy to maintain

CE certification & Utility model patent certificates

The forestry telescopic arm is modified for 12-15 ton excavators to expand from 23 to 28 meters, carrying a hydraulic grapple.
It is mainly used for some economic forest, such as eucalyptus and pine, to transport wood in short distance down or up the hillside. The back and forth expansion time is about 10 seconds, and the front end weight need to be less than 1 ton.
 

ZHONGHE forestry 3 section telescopic arm with grapple, which usually collect trees on the mountain.

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.A high quality grapple bucket is in the plan.

(Robust structure)
1. The box is made of LG700 high strength material
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  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.
