Mini excavators are one of the most widely used machines on UK construction sites due to their compact size and versatility. However, their small footprint gives a false sense of safety. Rollovers, pedestrian strikes, and service strikes are common incidents involving mini excavators. Operators must understand both the capabilities and limitations of these machines to work safely.
Key Hazards
Rollover on slopes, soft ground, or when tracking over obstacles
Pedestrians struck in confined areas where swing radius is restricted
Underground service strikes when digging without adequate surveys
Operator ejection during rollover when seatbelt is not worn
Control Measures
Ensure operators hold a valid CPCS or NPORS card for the mini excavator category.
Complete a daily pre-start check covering tracks, hydraulics, pins, lights, and seatbelt.
Wear the seatbelt at all times when operating the machine to prevent ejection during rollover.
Maintain a safe exclusion zone around the machine during slewing and digging operations.
Check for buried services using CAT and Genny before starting any excavation work.
Do not exceed the machine's rated capacity for lifting or digging reach.
Avoid working across slopes; always track up and down with the boom facing uphill.
Use a banksman when operating in confined areas or near pedestrian routes.
Lower the bucket to the ground, engage the slew brake, and remove the key when leaving the machine.
Remember
Always wear the seatbelt when operating a mini excavator to prevent ejection
Complete a daily pre-start check before operating the machine each shift
Check for buried services with CAT and Genny before digging anywhere on site
Maintain an exclusion zone around the machine during slewing and digging
Lower the bucket, engage the slew brake, and remove the key when leaving unattended
