Abstract

Excavators are frequently used as 'cranes' for object handling on construction sites, but this situation brings with it significant health and safety hazards that often, are not fully appreciated by stakeholders. These hazards are identified; their risks explained and studied; and appropriate advice for stakeholders explicated. A developmental approach is employed that embraces accrual of evidence; case studies; theoretical examination; and derivation of guidance. It is found that excavators are often used as cranes employing both 'formal' or less satisfactory 'informal' methods of load connection. Hazards from using excavators as cranes (found principally among load connection points and associated lifting accessories), are often 'hidden' and can lead to catastrophic failure during lifting operations. Stakeholders need to be aware of the hazards and implement suggested risk controls to remove or mitigate them.
