Heavy duty castors from Blickle

Blickle Räder+Rollen offers heavy duty castors in many variants. The product range features both pressed steel and welded steel heavy duty castors with a load capacity of up to 50,000 kg. In the standard range, heavy duty castors are available up to a mounting height of 710 mm. On customer request, Blickle develops tailored special heavy duty castor versions.

Definition of heavy duty castors

Heavy duty castors are used for applications with heavy loads and/or higher travelling speeds. Heavy duty castors feature a particularly stable design. To be able to absorb in some cases very high loads, heavy duty castors with two wheels (twin castors) are also used in this area. For vibration-free transport, spring-loaded heavy duty castors are particularly suitable. Typical applications for heavy duty castors include shelf stacking machines and industrial trucks, assembly and transport systems etc.

Heavy duty castors – selection criteria

The following selection criteria must be observed when selecting heavy duty castors:

  •     Load capacity
  •     Tread material
  •     Wheel Ø, starting and rolling resistance
  •     Bearing type
  •     Environmental factors, temperature, chemistry and corrosion

Determining the required load capacity for heavy duty castors

The required load capacity for heavy duty castors is calculated using the weight of the transport unit and its load, divided by the number of load-bearing heavy duty castors. The result is multiplied by a safety factor dependent on the standard conditions of the heavy duty castors:

T = Load capacity per heavy duty castor
E = Weight of the transport unit
Z = Maximum load
n = Number of load-bearing heavy duty castors
S = Safety factor

For heavy duty castors, the safety factor S takes into consideration deviations from the standard conditions (smooth floor, walking speed, uniform load distribution, travelling straight, ambient temperature from +15°C to +28°C). In addition to the speed, the safety factor is influenced by the ratio of the wheel Ø to the height of the obstacle. The greater the deviation from the standard conditions for heavy duty castors, the greater the factor S that must be selected.

A differentiation is made between four standard conditions:

Manual movement with heavy duty castors for indoor use:
(height of the obstacle < 5% of the wheel Ø): safety factor: 1.0 to 1.5

Manual movement with heavy duty castors for outdoor use:

(height of the obstacle > 5% of the wheel Ø): safety factor: 1.5 to 2.2

Motor-driven movement with heavy duty castors for indoor use:

(height of the obstacle < 5% of the wheel Ø): safety factor: 1.4 to 2.0

Motor-driven movement with heavy duty castors for outdoor use:
safety factor: 2.0 to 3.0

For heavy duty castors with ball bearings, speeds over 4 km/h are possible with a simultaneous load capacity reduction. If a wheel or fixed castor is primarily subjected to static loads, a load capacity increased by up to 25% can be assumed. In the event of long endurance times under high loads, the risk of the wheel tread flattening must be taken into account.

Starting, rolling and swivel resistance of heavy duty castors

The starting and rolling resistance of heavy duty castors is significantly influenced by the condition of the floor, total load, wheel Ø, deformation and treat type, as well as the bearing type.

The swivel resistance of heavy duty castors is influenced by the following factors:

  •     Tread
  •     Tread & tyre hardness
  •     Tread
  •     Offset
  •     Surface
The manoeuvrability of a transport unit depends on the number, type and arrangement of the heavy duty castors. These factors in turn influence the load capacity, mobility, control, turning radius and capsizing stability of a trolley.

Manoeuvrability with heavy duty castors

The heavy duty castors in particular must be positioned accordingly depending on the manoeuvrability and movability requirements for devices and machines. Below, different options for arranging the heavy duty castors are described:

  •     Three swivel castors of the same mounting height
  •     Four swivel castors of the same mounting height
  •     Two fixed and swivel castors of the same mounting height
  •     Two fixed and swivel castors, wherein the swivel castors have a somewhat lower mounting height
  •     Four swivel and two fixed castors of the same mounting height
