Manual materials handling capabilities in non-standard postures

Ergonomics, 1992
Research efforts to establish manual materials handling (MMH) capabilities of individuals and populations have been conducted for many years. Most of the previous efforts have explored 'standard postures', utilizing two-handed, symmetric, sagittal plane MMH using unrestricted postures.

The psychophysical approach to manual materials handling task design

Ergonomics, 1999
For approximately three decades, researchers have utilized psychophysics to develop guidelines (weights, forces and frequencies) for manual materials handling tasks. Early work by Stover Snook and his colleagues provided the foundations of the experimental methodologies that would be used by other researchers as well as design data that would be used ...

Obstacle clearance while performing manual material handling tasks in construction sites

Safety Science, 2014
Construction is widely known as having high rates of fall accidents. In spite of constant technological advances and increasing process automation, manual material handling still takes place in many construction tasks.

Handles for manual materials handling

Applied Ergonomics, 1980
The humble handle is one device available to designers of products and packages to improve the coupling between a human operator and the load he/she has to lift, hold or carry. Studies of handle design show that handles can help and that some are better than others but agreement on how handles should be studied, parametric values of 'optimum' handles ...

Evaluation of a curved handle and handle positions for manual materials handling

Ergonomics, 1986
Abstract Previous studies of handles for two-handed box handling have shown that the best angle for a handle on a box varies with height above the floor. In order to minimize the accommodation between handle and wrist required at different heights, a curved handle was proposed.

Experiments on wrist deviation in manual materials handling

Ergonomics, 1985
One potential hazard in manual materials-handling (MMH) jobs is the wrist deviation required when a container is moved. Container handles may help control this deviation, but if container handles are to be designed to fit the operator, an evaluation of the effect of wrist deviation on MMH tasks is required.

Usability of manual handling aids for transporting materials

Applied Ergonomics, 1995
Manual transport aids (trucks and trolleys) are in widespread use throughout most industries, but their use does not always result in the anticipated reduction of workload or musculoskeletal stress. A survey of users has shown that many of the aids currently used are poorly designed or inappropriate for the tasks performed.

Manual Materials Handling in Simulated Motion Environments

Journal of Applied Biomechanics, 2008
Seafaring occupations have been shown to place operators at an increased risk for injury. The purpose of this study was to understand better the demands of a moving environment on the ability of a person to perform specific lifting tasks. Subjects lifted a 15-kg load under four different lifting conditions.

The role of the hand in manual materials handling

Ergonomics, 1985
A sequence of studies were undertaken to clarify how the hand may be a limiting factor in manual materials handling. It was concluded that the design of an optimum handle to fit the hand is not too difficult, but that handle placement on containers is less easy to specify.

Analysis of multiple activity manual materials handling tasks using A Guide to Manual Materials Handling

Ergonomics, 1999
Manual handling of materials continues to be a hazardous activity, leading to a very significant number of severe overexertion injuries. Designing jobs that are within the physical capabilities of workers is one approach ergonomists have adopted to redress this problem.
