Frequently Asked Questions

Q1. How do I start to order?

A1. Firstly, talk to our sales about your machine model, working conditions, special needs and deadline. Then we will give you proposals FYR. You will receive a quotation within 24 Hours after confirming the proposal.

Q2. What is the length of the telescopic boom? Is it the total length of the boom?

A2. The length of the two-stage telescopic boom refers to excavation depth. For example, the 14m telescopic boom refers to the maximum excavation depth of 14m, not the boom length of 14m.

Q3. How to judge the length of telescopic boom that can be made for different models?

A3. 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.

Q4. Do I need to modify the original machine to fit the telescopic boom? Any precautions?

A4. The original machine needs three sets of pipes. The telescopic function is controlled by the original breaker pipe. We need to replace the original one-way foot switch with a two-way foot switch. The more important thing is balance and safety. Try to avoid the 90 degree operation between the cab and the track shoe.

Q5. Note and maintenance of telescopic arm

A5.

Telescopic arm does not allow inclined excavation
Can't dig hard things but only soft soil
Not allowed to jack or hoist when the smallest arm is not fully retracted
End can't lift things more than 1 ton
Telescopic boom shall be greased every day
Boom barrel shall be greased at least once a week
