This document outlines a risk assessment for lifting operations with a mobile crane, detailing potential hazards, risks, and control measures to ensure safety. Key areas of concern include crane operation checks, site access, crane setup, equipment lifting, and crane maintenance, each accompanied by risk ratings and recommended safety practices. Various control measures are proposed to mitigate risks, and specific supervision and training requirements are highlighted.

Crane checks on
arrival to site
PRIOR TO USE
 Use of mobile crane
 Unauthorized operation ofthe mobile
crane resulting in incident;
 Failure due to use of un-certificated
crane;

HIGH
i. All cranes to be Third Party Certificated by a DM approved inspector,
documentation available on arrival to site;
ii. Operators to have in-date Third Party certificate by approved body,
available for review on arrival to site;
iii. Crane load indicator to be installed and functioning correctly;
iv. Visual inspection ofcrane undertaken by competentperson;

Access of crane to
work areas
 Plant and workers in
same working area;
 Collision with plantor vehicles and
live traffic;
 Workers struck by plant, very high
risk of fatality;
 Uncontrolled crane reversing;
i. Worker pedestrian routes to be designed and implemented with clear
signage to provide segregation;
ii. Instruction to workers at induction on use of access routes around the
project;
iii. Flagmen to be used to control crane movements;
iv. The Logistics plan shall clearlyillustrate crane access and egress points;

3 Siting and setting up of
crane
 Working in proximity
to existing structures
and services;
 Overturning due to incorrectsiting or
incorrectoutrigger extension;
 Collision with overhead services;
 Blocking access routes;
 Load striking moving and/or
stationarystructures;

i. Ensure crane is setup/rigged out correctly, is on firm level ground as per
crane plan with outriggers fullyextended;
ii. Solid barriers should be situated,where practicable,to protect crane from
traffic routes around working radius ofcab;
iii. Consideration given to overhead services and existing structures when
siting crane;
Unable to fully
extend outriggers

(Mobile crane
Operator)
 Operator competency;
 Lift planning;
 Incidentdue to use of defective
lifting gear / equipment;
 Crane collapse due to lifting loads
beyond SWL;
 No crane documentation in place;

i. ATC Minimum Acceptable Standard ATC/OHS/MAS/00941 to be adhered
to at all times;
ii. Lift Plan to be completed prior to any lift taking place by crane supervisor
and engineer;
iii. Ensure all lifting tackle and equipmenthave valid test certificate before
use (6 monthly3rd
party inspections);
iv. Method statements and risk assessments to be submitted and adhered to
for technical and/or non-routine lifts;
v. Crane load indicator to be functioning correctly, and not to be overridden
under any circumstances;
