SELECTING THE RIGHT CASTOR

Types

It pays to choose castors with care.
Selecting the right castor ensures
that the first cost will be the most
economical.

Installs

There are different ways to install the
castors based on the load.

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.
