SELECTING THE RIGHT CASTOR
It pays to choose castors with care. Selecting the right castor ensures that the first cost will be the most economical.
There are different ways to install the castors based on the load.
Before choosing a castor you should view our handy symbols guide where we explain the different meanings of the symbols.
ENVIRONMENTAL FACTORS
CAPACITY
What will the maximum load be? Don’t forget the weight of the actual truck. Does the possibility of overload, shock-loading, abuse or poor floors call for a safety factor?
FLOOR CONDITIONS
Are they smooth or are there holes? Are there obstacles such as elevator sills, railroad tracks or dock plates? Are there metal shavings or threads or harmful substances on the floor? The use of a wider faced wheel prevents indentation or gouging of good flooring.
OPERATING ENVIRONMENT
Is noise a factor? Must the castor work in confined areas? Are water, oil, grease, chemicals or extreme temperatures present? Frequent movement demands longer wearing components than occasional movement
TYPES
CASTORS
Castors are components which are fitted to objects to make them mobile. Generally castors are designed for low speeds only, mostly pushed or pulled manually. Castors consist of a bracket and at least one wheel.
SWIVEL CASTORS
Swivel castors are vertically rotatable. A fork is fitted to a top plate of a swivel bearing. The fitting element is firmly fixed to an object while the fork remains rotatable. A swivel offset is dimensioned to enable directional stability resulting in a smooth swivel motion.
FIXED CASTORS
Fixed castors provide directional stability. Generally fixed castors are supplied with top plates for fitting.
