Thwaites dumper cab impact test

Impact test conducted on a 9-tonne Thwaites dumper at the company’s proving ground in Leamington Spa, November 2019.

Test 1: Testing the structural integrity by striking the cab at the A pillar.
Findings: No failures were observed or reported on inspection, the energy of impact was absorbed through the cab structure.

Test 2: Testing the fully finished cab by striking the cab at the front via a screen guard.
Findings: No failures were observed or reported on inspection. The screen guard performed well in absorbing the initial impact with the force being distributed through the cab frame.

Despite this, Thwaites recommends that, in conjunction with Contractors Plant-Hire Association and Health & Safety Executive guidance, operators do not remain in the cab during loading.
