Tips on How to Be an Excavator Operator

Why there are special requirements for the operator. Because using excavators as cranes is a high risk activity and lifting is not the primary design function of these machines. Anumber of dangerous occurrences have recently occurred where chains, shackles or master links have either deformed or broken whilst loaded. Such incidents occur primarily because the load is not freely suspended from the lifting point.

Instead, lifting equipment is wrapped over the lift point therefore creating rotational forces that multiply the load many times over (depending upon the geometry of the machine and its liftingequipment). Forces created are invariably many times greater than the rating of the slings or chains used. Load swing whilst a machine is travelling, or unexpected movement of the machine whilst lifting gear is attached, are other commonly reported problems that cause contact with, or crushing, injuries and fatalities.

Excavators should only be driven by fully trained, competent operators who have been authorised to do so and any operationshould be accompanied by a suitable risk assessment. The nationally recognised qualification for competence within Britain is a Scottish/National Vocational Qualification (S/NVQ) Level II Plant Operations.

For lifting operations, operators must also provide proof of both training and competence for using used excavator as cranes. This will include knowledge and skills relating to: pre-lift checks; differences between various lifting accessories or machine attachments (e.g. quick hitches);load connection procedures; interpreting the machine's lifting duties limitations at varying radii, over the front, side and rear of the machine (dozer blade up or down); travelling with a load; and load disconnection procedures.
