New dredger delivered to Broadway
First customer for the latest Richard Smalley 363MkII amphibious dredger is Barry Westby Groundworks of Broadway, Worcs .

This updated design has a larger 63 kw ( 83.5 bhp) at 2,500 rpm water cooled diesel engine, lifting capacity increased by 20%, capable of loading a full 400litre bucket every time. PTO as standard piped to the end of the jib providing three separate power take offs, one for driving mud pumping or other auxiliary equipment , one for addition al double acting hydraulic ram operation and the third for hydraulic grab rotation/ hydraulic motor operation. All controlled by electric servo press button controls either on the hand levers or the dashboard for precise control and operation other hydraulic equipment such as pile driving, chainsaw or mud pump. The hydraulic system has been improved to incorporate a more efficient cooling system to accommodate its ability for long hours of mud pumping.

The machine retains full 360° slew, amphibious capability to access rivers, ponds, canals, estuaries etc without the need for a crane. Working from the water makes more areas accessible, not restricted by riverine properties but with 7metre reach can unload into a barge or tubboat or over embankments. This model features a removable cab leaving seat and hydraulic controls intact, essential to access those areas where work has always been restricted by low bridges or other obstacles. This removal is facilitated by a small demountable crane. Air draught with whole cab removed is 1.44 metres approximately.

 Richard Smalley amphibious dredgers have been sold throughout the world since 1982, its ability to be carried on a standard flat bed truck from site to site, load and unload itself without needing a crane and still access clogged waterways has made it a market leader in small dredging machines. The dredger consists of a purposefully designed excavator with specialised geometry for the jib and dipper to offer an excellent reach and good dipper geometry designed to prevent the bucket from piercing the pontoon when digging close to the machine.

The pontoon is mounted on 3 pairs of 1.2 metre diameter hollow wheels, these provide flotation in the water and support the machine on land for movement between vehicle and embankment. This latest model builds on experience gained in New York Central Park, Mumbai, Colombo, Gt Ouse and Thames rivers, Colombia and Florida
