HEFEI SUNTON MACHINERY MANUFACTURING CO., LTD.

SUNTON SP series Supplementary Pontoons and Spuds Stabilizers are compulsory attachments to the amphibious undercarriage pontoons to ensure the stability of the machine when it’s operated on deep water. Supplementary pontoons are also called side pontoons or stabilizers, which can be easily attached onto the outer side of the amphibious pontoons. Without the side pontoons and spuds, the dredging operation will be dangerous because the machine is unstable and even turns over when the machine is entirely floating on the deep water.  The spuds are foldable spuds and all the activities of the spuds including standing, lying, positioning and rising etc are hydraulically controlled by the operator in the cab.  The spuds length could be custom-designed as per the water depths concerned. Normal side pontoons are usually equipped with 2 spuds in total. As an optional choice, SUNTON could also build 4-spud side pontoon stabilizer for more stabilities when machine being operated on open water with high current speed and large waves.  SUNTON also custom builds other types of supplementary pontoons for bring more buoyancy to the machine, as central pontoon that put between the two amphibious pontoon to enhance buoyancy of the machine. 3.2 Small and Medium Size Side pontoons and Spud Stabilizers Model SP120 SP180 Pontoon Length, mm 4000 4 500 Pontoon Width, mm 750 1 250 Pontoon Height , mm 750 750 Spuds, mm 180/6000 245/8000 Total Weight of Stabilizers, Kg 4000 5000 Total Buoyancy, Ton 4 8 Matched AHUs PU80 PU120 PU140 PU160 PU180 Excavator Class Fitted to 5-6tons 5-8tons 5-10tons 8-12tons 10-16tons Total Buoyancy, Metric Tons 13 17 20 23 24 Max.
