FAQ of Telescopic Excavator Boom
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.
