Ergonomics of single-handed pulling : a biomechanical and psychophysical assessment
… of biornechanical events measured during manual materials handling (MMH) activities has been a major focus for ergonomists attempting to understand the relationships between performance factors and injury mechanisms. Pulling exertions, while being frequently observed in occupational …

Designing and modelling an automated packaging system
… the design and modelling of an improved materials handling system for a beverage cap production factory called BevCap, located in Epping, Cape Town. The factory consists of twelve production lines, which produce various types of aluminium and metal screw on caps. Each production line is …

Assessing Trailer Material Handling Tasks: Biomechanical Modeling, Posture Categorization, Physiological Measure, and Subjective Rating
… are available to aid the human operator in manual materials handling (MMH). This thesis describes an investigation to determine which of four different designs used in trailer MMH place the least physical stress on the human operator when unloading materials. Each trailer MMH design was …

Effects of Chemical Protective Clothing on Task Performance using Wearable Input Devices
… shown that protective clothing interferes with manual materials handling tasks, medical tasks, and manual dexterity tasks. However, little information exists regarding how protective clothing affects task performance with wearable input devices. As a result, a study was conducted to address this …

The Correlation Between Biomechanical Loads and Psychophysical Ratings
… last three decades for evaluation and design of manual materials handling tasks in many industries. Despite this, much is still not known about how subjective ratings, the core of the psychophysical methodology, relate to physical (biomechanical) loads. A fundamental assumption of this method is …

Balancing efficiencies and tradeoffs in epidemiological field studies : evaluating EMG exposure assessment for low back injury risk factors in heavy industry
… Observations and self-reports of posture, manual materials handling (MMH), and driving exposures were collected concurrently. 1) Variability of EMG calibration measurements was investigated on right/left sides, multiple trials, 4 positions, and pre/post-shift. Position accounts for the …

The effect of a commercially available abdominal support belt on torso posture, lift strength, and spinal compression
… the wearing of abdominal support belts when manual materials handling activities are performed. However, poor postures and restricted ranges-of-motion may result due to belt usage. Unfortunately to date, the majority of research available regarding support belt effects only address those …

Prediction of Whole-body Lifting Kinematics using Artificial Neural Networks
… to task design and analysis, especially for manual materials handling (i.e., lifting) exertions. In turn, accurate models that predict posture and kinematics can reduce the need for empirical postural and kinematic data in this task development process. Artificial neural networks were used in …
