Q690D Boom Arm

15 m Long Reach Arm for 20 Ton Excavators

Fifteen metres is the most ordered length in our workshop, because it fits the largest group of 20 ton machines in service and still travels on a standard low bed trailer when the sections are split.

Reach is 14.6 m and digging depth 10.8 m with a 0.5 m³ bucket. We reinforce the boom foot with Q690D plate and lengthen the counterweight package, so the carrier is not working on its limit at full extension.

Talk to our factory engineer on WhatsApp: +86 180 2625 4557 — send your machine model, stick length and working depth, and we return a drawing and quotation within one working day.
