Taylor cuts noise and vibration on tracked dumpers

PLANT

TAYLOR Construction Plant has cut both the noise and hand-arm vibration levels of its popular Hi-T500 tracked dumper.

The redesign has been made to meet new EU noise regulations which come into force in January 2006, and in response to customer feedback.

Managing director Andrew Barker said: 'The target we gave ourselves was 100 dB(A), down from 104 dB(A), and we've achieved 99 dB(A).' This drop in decibels from the previous model results in a significantly quieter machine, despite being powered by the same Kubota diesel engine.

To achieve the reduction TCP has completely enclosed the engine and hydraulic motor in a two-piece GRP cover, which is lined with acoustic insulating material. In addition the engine is now mounted on isolating rubber mounts, and not bolted directly to the frame.

The anti-vibration engine mounts are said to reduce vibration levels at the control handle by around 20 per cent.

The dumper has a new engine management system, which will not allow the starter motor to turn until the glow plugs have reached operating temperature.

TCP has also upgraded its mini-crusher, which also uses the Hi-T500's tracked running gear. It also incorporates the new anti-vibration engine mounts, but not the engine encapsulation, as static crushing equipment is not covered by the same regulations.
