A machine travelling at 9.2 mph collided with a stationary work MEWP on the tracks between Rochford and Southend Airport stations last month.
The machine had travelled over 150 metres immediately before the collision and was being used to renew the overhead electrical power lines.
Two workers in the stationary MEWP were thrown against the railings of the machine’s basket.
They both suffered severe bruising and back injuries which prevented them from working for some time.
The single person in the moving MEWP was unhurt. Both machines were slightly damaged.
The investigation will identify the sequence of events which led to the accident. It will also consider:
- The arrangements for managing the movement of the MEWPs, including the planning and organisation of the work that was taking place
- The management of the competence of machine operators and controllers
- The braking performance of the MEWP
- Any underlying factors.
