The use of quick joint in the replacement of various configurations, no need depart pins manually, the excavator operator in the cabin gently move the switch to replace the attachment within 10 seconds, saving the time when replacing accessories, greatly improve the work efficiency.

Production Process

1.Panel is cut by CNC plasma machine with less deformation

2.Each welder has more than ten years of experience to ensure stable quality

3.environmentally friendly verified spraying room

4.professional and beautiful paint finish

5.three layers with four passes welding

6.Graphite alloy copper sleeve

7.Seamless precision steel pipe

8.Centralized lubrication system

The equipmets we have:

CE certification & Utility model patent certificates

We use a variety of packing materials, including wooden crates, pallets, and other materials that are suitable

for the specific product and shipment. Our team carefully inspects each package for quality assurance before shipping.

1. How do I start to order?
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.
2.Why not have boom and stick cylinders in the plan?
A1: First, the whole long arm is lengthening, but the boom just lengthening from its middel sleeve to its end, so the original boom and stick cylinder can be used. Second, using the original parts can save your cost.

3. Are you alaways delivered on time?
We can't promise about the freight but what we can do is shortening our lead time while keep the same quality level. So there will not be any problem even if the sea freight delay for a couple days. Our annual output of various types of excavator boom arms can reach 600 sets.

4. How long is the boom arm can mini excavator be be configured with? Whether it is necessary to increase the counterweight?
A2. Generally speaking, 30-40 excavator longest arm suggests to be 8 meters, can configure 0.1 cbm bucket, no need extra counterweight. 55 excavator longest arm suggests to be 12 meters, can configure 0.1-0.15 cbm bucket, need 0.5 ton extra counterweight. 60-80 excavator longest arm suggests to be 12 meters, can configure 0.15-0.25 cbm bucket, need 0.5-0.7 ton extra counterweight.
It is not recommended to extend boom arm to longest length as min excavator is easy to sloshing.

With reference to the efficiency of Chinese workers, and tools are fully prepared, it only takes one day to complete the disassembly and assembly.
Kindly remind, prepare several containers to fill the oil before disassemble.
