MISSIONTo broadly promote the benefits ofergonomic assist systems and equipmenttogether with the advantages derived fromthe use of this equipment in the workplaceand to promote the safety and health of thework environments.
Why AddressManual Material Handling?
The effects of manual materialhandling represent the biggestsingle contributor to workerinjury in the United States andthe application of goodergonomic programs can reducethose incidences.
These unnecessary worker activitiescan result ergonomic problems
Lift & Turn to position large valves during assemblyTurntable
The assembly, wiring start-up and testing of these largedevices requires access to all sides, top and bottom
Vacuum lifters areefficient and veryuseful in areaswhere sortingcontainers is creatingmultiple pick andplace tasks
Bench topdevices likethisadjustableheight standor thisturntable allowcompleteaccess to thework whileseated orstanding
High density verticalstorage systems puteach item at thecorrect height
Manipulators making easy work of handlingcylinder heads in a machining center
IAD -Intelligent Assist DevicesAmplifies operator’s powerUnit has an intuitive, humanlike feelIntuitiveThe operator has a sense ofcontrol & feel over the load usingnormal arm, wrist and handmovements.IntelligentResolver feedback from theservomotor allows for futureimplementation of programmablehuman limits.

These manual devices reduce carrying loads
They come in allshapes and sizesand to gain themaximum benefitshould applied tothe application
Some care should be usednot to overload carts

PalletsApproximately 450 million new pallets producedeach year in the USA. 1.4 billion (est’m) palletsare in use at any given time.MANUAL LOADING AND UNLOADINGOF PALLETS CONTINUES TO BEONE OF THE MOST COMMON ANDMOST INJURY PRONE TASKSIN INDUSTRY TODAY
Here is a very typical problem
These are automatic load leveling devices that maintainthe top of the load in the 30 to 40” ergonomic window
Lifts andpositionerscan also befitted withturntables for“near side”loadingAs much as 40% ofthe time requiredloading a pallet, canbe spent walkingaround it!
Lifts fitted withturntables eliminatewasted motion . .and put the load atthe right elevation toreduce the possibilityof back inquiry
Notice the bi-directionalwork station craneBalancers can also beused to unload palletsand make positioninggoods at variouslocations within amachine or workcenterthese trays of parts become virtually “weightless”
These lightweightlifts are highlymaneuverable
Inexpensive stackers to transport pallet loads in and aroundwork stations - even load/unload directly from them
This is a reallycheesy job!This vacuumlifter makeseasy lifting andmaneuvering ofthese heavycheese wheels
ContainersManual loadingand unloading ofwire baskets, containersand Gaylord's leads toa high incidence oflower back injuries
Issues: Back bending,back extension, overreaching, fatigue andproduct loss
ProblemSolution
Parts picking made productive from fixed height tiltersNotice the high hinge causing thecontainer to elevate as it tilts
This springloadedpositionerelevates thegoods in thecontainer toeliminate thebending
This lift and tilt provides access to all of the parts in this container
Parts picking on assembly line

ergonomics, engineering project, control centre, case studies 1. Marketing ergonomics 1.1. Ergonomics Ergonomics (or human factors) is described as fitting tasks, workplaces and interfaces, to the capacities, needs and limitations of human beings.

Ergonomics Risk Factor Ergonomic risk factors are characteristics of a job that facilitate ergonomics stress on the body. Risk factors occur at different jobs and tasks. The greater exposed to these risk factors the greater probability of ergonomics. According to [1], ergonomics risk factors can be divided into seven categories as follows:
