Bases
5 Star Spider Base - 600mm Diameter
A new 600mm diameter glass reinforced nylon five star spider base with tapered steel spindle bush. Manufactured at our factory in Germiston - a 600mm dia. glass reinforced nylon base. This is available with our new castor - the 50mm dia. Apollo Executive model A tapered steel reinforcing ring is moulded into the center to ensure that the spindle remains in position and does not creep Sturdy ribs are incorporated into the design to ensure that with the glass filled material used minimum flexing occurs.
No load applied and spindle inserted
Under full load - 1000 kg
Our base is measured for deflection and spindle movement.
Testing of our bases is done at our premises in Elandsfontein this ensures that our products meet with the highest international standards. Castors are tested by an independent international manufacturer of heavy duty industrial castors
The complete unit - base and castors is tested by the South African Bureau of Standards to SABS 1528-1 " Test for castors & five star base", with the relevant report available for inspection.
In the picture on the left the Chatton 600mm dia base is shown with no load applied.
In the picture on the right a load of 1000 kg is applied.
5 Star Chair Base - 600mm Diameter
Manufactured from Glass filled Nylon this 660mm diameter five star office chair base is designed for the most rugged conditions.
A steel reinforcing ring is moulded inside the tapered 50mm diameter orifice to prevent spindle "creep" as well as giving the base extra strength.
The castors are our Venus 50mm Twin Wheel Executive castors with a push - in 10mm dia.pin.
An identical base and castors has been tested by the SABS to eight times more than the required standard. The relevant report is available on request.
These along with all our products, are made at our factory in Elandsfontein, Germiston.
Testing for deflection, spindle creep and failure.
The base to be tested is placed on the test rig supported by levellers inserted into the castor pivot holes
A steel mandrell made to the same dimensions as a spindle is inserted in the centre hole and the distance of penetration measured. The distance from the bottom of the base to the base of the test rig is measured See pic "A". Hydraulic pressure is applied and measurements taken at various points Our bases are tested to a load of 1000 kg without failure.
The deflection at this point can be seen in pic "B"
This test when compared to those conducted on "imported bases" equals and in some cases even surpasses them giving us confidence that our product is sure to give trouble free service throughout the life of the chair.
