Telescopic Pontoon Undercarriage (Extensible Amphibious Undercarriage)

Telescopic Pontoon Undercarriage (Extensible Amphibious Undercarriage)

General Information:

SUNTON EPU series telescopic pontoon undercarriages (Amphibious Undercarriage) are an optional design of the normal standard PU series marsh undercarriages. The extendable undercarriage could retract and extend outward hydraulically. The width of the small size undercarriage could be adjusted to 3m as a minimum. The hydraulic control is totally independent from the existing hydraulic circuit, which could be fully controlled by the operator in the cabin. The design of the extendable pontoons provides the most convenience of transporting the complete machine on trailer without dismantling it into modules. This brings a tremendous saving on logistics.

As per custom’s request, we could provide the manually extendable pontoons, which is also a practical optional choice to meet customer’s budget. It can realize retraction and extension only through a pulling-block pulled by a machine as an excavator. Detail specification will be provided under request.
