Many of us fairly regularly spend time pushing a heavy trolley around, usually at the supermarket. Supermarket trolley which are poorly designed can be very difficult to manoeuvre, and people are finding that whilst pushing them around, they are straining their backs and knees. Research has been carried out which has proven trolleys to be a definite cause of back and joint problems.

It is not only supermarket trolleys which cause problems for people, but trolleys used in warehouse, industrial sites, shops, garden centres and many other places. Many of the problems caused and aggravated by manoeuvring heavy trolleys can be eliminated by ensuring you are using the correct type of trolley for the job in hand. It is easy to get into a habit of using just one or two basic types of trolleys for jobs which those particular trolleys are not suitable for.
There are many different types of trolleys specially designed for particular uses, including Newspaper trolleys, sack trucks, light duty trolleys, stair climber trolleys, post room trolleys, coffin trolleys, platform trucks, tray trolleys, board trolleys, garden centre trolleys, drum and container trolleys and two way hand trucks. 

Each of these particular supermarket trolleys is designed to be used in certain situations. For instance, a sack truck is used to manoeuvre heavy objects by levering them off the ground using the trolley foot, and transporting them, pivoting on the two wheels. Platform trucks have a flat base and four solid wheels; they are very stable and are used in transporting many different objects. Stair climber trolleys are designed with a special three wheel mechanism which enables the trolley to roll up stairs with very little hassle.
So essentially a lot of the back and knee troubles which are caused by trolleys, can be greatly reduced if we ensure we are using the correct trolley for the job in hand.
