Frequently Asked Questions

How do I start to order?

Contact our sales team with your machine model, working conditions, special requirements, and deadline. We'll provide proposals and a quotation within 24 hours.

What is the length measurement of the telescopic boom?

The length refers to maximum excavation depth, not the physical boom length (e.g., 14m refers to 14m digging depth).

Do I need to modify my excavator?

The original machine needs three sets of pipes. The telescopic function requires replacing the foot switch with a two-way version. Balance and safety are critical - avoid 90° operations between cab and track shoe.

Maintenance Guidelines

Do not perform inclined excavation
Only suitable for soft soil, not hard materials
Never jack or hoist without fully retracting the arm
Maximum 1 ton lifting capacity at arm end
Daily greasing required, with weekly boom barrel lubrication

Packaging & Shipping

Standard packaging includes bubble bags for most products, wooden cases for smaller items like buckets, and iron frame support for boom arms.
