Operator Crushed In Articulation Point Of Loader
What A loader operator received fatal injuries when crushed within the articulation point of a load haul dump vehicle (LHD). The operator had left the cabin, with the bucket tilted backwards, whilst the engine was running. Why Inoperation of the engineering steering control... Read more
Kanga loader overbalances catapulting operator into pit
What While magnetite was being dumped from a G-524 "Kanga Loader", the operator leant forward to look into the pit, causing the loader to overbalance and catapult the operator over the top of the machine. Why The machine was handling a load greater... Read more
An Ergonomic Evaluation of Excavating Operations: A Pilot Study
What "The objective of this study was to systematically characterize the ergonomic hazards associated with excavating operations." ... Read more
Ergonomic Risk Factors: A Study of Heavy Earthmoving Machinery Operators
What This paper reports the results of a study performed to evaluate ergonomic exposures among operators of heavy construction equipment. It also provides recommendations for reducing ergonomic exposures such as vibration and postural stress. ... Read more
LHD Operator Posture Assessment
What To determine the postural deviations and low back load required for line of sight from the operator's position. Why The bi-directional nature of load haul dump (LHD), vehicle design dictates the operators sit in a centrally located seat position, perpendicular to the... Read more
Biomechanical Modeling of Spinal Loading due to Jarring and Jolting for Heavy Equipment Operators
What "This paper describes the development of a multi-body biomechanical model that can be used to assess the risk of low back disorders due to occupational exposure to jarring and jolting from operation of heavy mobile equipment (e.g., trucks, haulers, graders,... Read more
Whole-body vibration and postural stress among operators of construction equipment
What It has been suggested that operating engineers (OEs) are exposed to two important risk factors for the development of musculoskeletal disorders: whole-body vibration and non-neutral body postures. This review evaluates selected papers that have studied exposure to whole-body vibration and... Read more
Protective Structures for Low-Coal Shuttle Car Operator
This report discusses Bureau of Mines efforts to develop partial protective structures for operators of low-coal shuttle cars. Three possible limited-coverage design scenarios (roll bars, sliding canopies, and flip-top canopies) were designed, fabricated, and evaluated for low-coal shuttle cars. All... Read more
Self-Reported Musculoskeletal Symptoms among Operators of Heavy Construction Equipment
This study assessed the adequacy of cab design and determined the percentage of musculoskeletal symptoms among operators of heavy construction equipment. Workers through a questionnaire adminstered to 189 operators. The results indicate that these workers are at risk for developing... Read more
Haul Truck Pre-operational Hazards
Many accidents have occurred due to slips or falls while climbing up on to large surface mining equipment. Foul weather magnifies these hazards. It takes very little ice, rain or mud to make the climb much more hazardous. If the... Read more
Vibration Related Back Injuries to Operators of Mobile Equipment in NSW Coal Mines
This document examines the association between whole body vibration and low back pain by surveying the available literature and analysing the Joint Coal Board's accident reports for the previous ten years. It discusses spinal anatomy, ageing and degeneration of the... Read more
Operator Killed Changing Tyre
What An operator was fatally injured when changing a tyre on a rear dump truck while using a radio controlled truck mounted tyre handler. Why The operator was using a radio remote control transmitter to control the tyre handler, which was mounted on... Read more
Equipment automatic operation can be hazardous
What An operator had two fingers pinned and a third severely lacerated when a bolting rig auto retracted. The ring finger and the tip of the middle finger were later amputated surgically (past the second knuckle). Why Operator was attempting to do multiple... Read more

"Adjust it yourself" Operator Adjust Mirrors
Problem Current truck mirrors are non flexible and require operators carrying tools to adjust mirrors due to seized bolts. Solution A stainless steel, lightweight mirror is refitted on all trucks with increased adjustability and decreased risk to personnel. Benefits Improved skilled tradesman utilisation to high...

A GPS Based System for Minimizing Jolts to Heavy Equipment Operators
What Describes a method for assessing equipment jolting using a combination of "black boxes" called Shox Boxes and an onboard GPS system. The Shox Box system reviews data in real time, onboard the vehicles, 24 hrs a day, and sends pertinent... Read more
Rio Tinto Safety Standards: C. Operations Standards: C4. Working at Heights
The Rio Tinto safety standard for Work at Heights. Main areas of coverage are the design and use of Fall Prevention and Fall Protection equipment. Guidelines for the use of ladders and barricades are also given. This standard is applicable... Read more
Driller's Off-sider Injured while Operating an Exploration Drill Rig
What The rod clamps on an exploration drill rig closed down onto the foot of a driller's off-sider. Why The investigation found that the circumstances of events were as follows: Drill rods were being "pulled" using a rod spinner . . . Recommendations All exploration... Read more
Fatality at sand and gravel operation
What A labourer with 32 years experience (2 days at the mine) was fatally injured at a sand and gravel operation. The victim went behind a guard, used a wooden handle shovel to clean under a conveyor belt take-up pulley, and... Read more
Reducing Enclosed Cab Drill Operator s Respirable Dust Exposure at Surface Coal Operation With a Retrofitted Filtration and Pressurization System
This report discusses a cooperative research study performed on a surface drill retrofitted with a new pressurization and filtration system. Respirable dust concentrations were substantially reduced from 0.64 mg/m3 during pre-testing to 0.05 mg/m3 during post-testing with the new system,... Read more
