Frequently Asked Questions

How do I start to order?

First, discuss your machine model, working conditions, special needs and deadline with our sales team. We will provide proposals and a quotation within 24 hours after confirming requirements.

What is the length of the telescopic boom?

The length refers to maximum excavation depth, not boom length. For example, a 14m telescopic boom provides 14m maximum excavation depth.

How to judge the appropriate telescopic boom length?

Length is determined by ensuring the boom won't touch the bridge when placed on the ground, based on your specific machine model.

Do I need to modify the original machine?

The original machine requires three sets of pipes and replacement of the foot switch to control telescoping function. Important safety considerations include maintaining proper balance and avoiding 90° operations between cab and track shoe.

What are the maintenance requirements?

Key maintenance includes daily greasing of the telescopic boom and weekly greasing of the boom barrel. Important usage restrictions include no inclined excavation, no hard material digging, and no lifting over 1 ton at the boom end.
