More Product Details:

It's my big pleasure to share with you some advantages of our three-section telescopic boom:
1. Material: the material of the tube is BS900E. lighter, stronger, longer life-span.
2. Pulley: The pulley is made of MC steel, which has the same hardness as steel, but is light and wear-resistant. The wheel diameter is enlarged to withstand greater loads.
3. Bearings: The bearings are high-speed heavy-load bearings, and the bearings use larger diameters to withstand greater loads.
4. Wire rope: using multi-strand wire rope can bear greater tension and impact force.
5. Excellent design: Very few failures, and later maintenance is more convenient.
6. Production process: Using better welding wire and better processing technology ensure the accuracy of the arm tube.
7. Telescopic boom is our mature product. Positive feedback.

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.
