This Standard was published on 1 February The following are represented on Committee CS To maintain their currency, all Standards are periodically reviewed, and new editions are published. Between editions, amendments may be issued. Standards may also be withdrawn. It is important that readers assure themselves they are using a current Standard, which should include any amendments which may have been published since the Standard was purchased. Alternatively, both organizations publish an 22693 printed Catalogue with full details of all current Standards.

For more frequent listings or notification of revisions, amendments and withdrawals, Standards Australia and Standards New Zealand offer a number of update options.

For information about these services, jzs should contact their respective national Standards organization. We also 22693 suggestions for improvement in our Standards, and especially encourage readers to notify us immediately of any apparent inaccuracies or ambiguities.

Please address your comments to the Chief Executive of either Standards Australia or Standards New Zealand at the address shown on the back cover.

The objective of this Standard is to provide manufacturers, importers, consumers, retailers and testing bodies with a set of performance requirements which includes technical ass and test methods 293 various types of jacks intended for raising passenger vehicles. This edition revises the warning notices. Suppliers of vehicle jacks should take cognizance of the regulations under the Trade Practices Act relating to the supply of these products.

A ‘normative’ appendix is an integral part of a Standard.

It does not include devices that raise an entire vehicle. The performance requirements include those relating to ease of use. A summary of requirements according to vehicle jack type is given in Appendix A.

This includes any mass imposed on the towing vehicle when the combination vehicle is resting on a horizontal supporting plane.

This applies for all measurements of operating force. The force is measured at the centre of the handgrip or, if there is no handgrip, at a point 50 mm from the operator’s end of the handle. The rotation of the screw alters the geometry of the frame, thus lifting or lowering 26933 load see Figure 1 c. The projected plan area of the base should be measured when the head cap is fully raised. A specific vehicle jack is only intended for changing wheels.

It shall be free from defects that would affect its durability or serviceability, and ail screws, pins, bolts and similar parts shall have effective means for preventing loss of proper tightness and adjustment. All bearings and moving parts requiring periodic lubrication shall be provided with readily accessible means of lubrication. If the jack is not supplied in a fully lubricated condition, it shall be provided with adequate instructions for initial lubrication.

Hydraulic jacks shall be supplied with hydraulic cylinders filled to the correct level with the recommended hydraulic fluid. The design of the jack shall allow for a changing angle between the column and baseplate, and column and vehicle, as the vehicle is being raised.

General purpose jacks may have a rotating head cap. High lift jacks need not comply with this requirement. The provision of a relief port on a hydraulic jack may be an effective means of preventing overtravel. For the purpose of this requirement, the vehicle shall be at its maximum loaded mass and the tyres shall be selected from the manufacturer’s recommended range of road tyres so as to provide the most severe condition.

Special emergency spare tyres shall not be used when assessing compliance with this requirement. Special emergency tyres shall not be used when assessing compliance with this requirement. A new jack may be used for each test if required. The handle provided for operation of the jack should, at the area where the operator applies the operating force, be of a size and shape which does not cause undue discomfort. The instructions may be provided in pictogram form. This advice may be provided in pictogram form.

This warning advice may be provided in pictogram form.

In addition to the assembly information and the instructions marked upon the jack in accordance with Clause 7. During these tests it is desirable to have chocks placed near the wheels but not in contact with themor to provide some other means of preventing excessive movement of the vehicle in the event of a jack failing the tests.

The vehicle used in the tests shall 293 one designated as suitable nzd use with the jack under test. L1 Specific vehicle jacks The test shall be carried out with the vehicle at its unladen mass.

The head cap and jacking points shall be clean and dry and free from oil, grease and other deleterious substances. An impulsive force shall be delivered to the head cap in the direction most likely to cause disengagement of the head cap from the jacking point. A method of achieving this is to use a weight of 7 kg mass attached to the end of a pivoted arm of mm length which shall be allowed to swing through an angle of 10 degrees from vertical.

The impulsive force at the lower end of the swing shall be applied to the head cap either directly, where applicable, or via a friction-free steel pushrod where the jack is not readily accessible see Figure Bl.

AS-NZS 2693: Vehicle jacks

Other methods of delivering an equivalent impulsive force to the head cap may be used as an alternative. With the vehicle raised, a force of N shall be gradually applied to the vehicle, at a height of 0. The force shall be sustained for at least 30 s. This Appendix also includes a method for testing whether it is possible to induce overtravel in a jack.

It shall be tested using all jacking accessories supplied. Tests shall be carried out on a substantially level concrete surface or its equivalent. The jack shall be prepared for use in the normal manner, in accordance with the manufacturer’s instructions. If the jack requires lubrication during the test it shall be in accordance with any lubrication requirements contained in the manufacturer’s instructions.

Lifting cycles shall be carried out at a rate which corresponds to actual use and repeated at intervals which are sufficiently long to prevent overheating. Where a dead weight is used it shall be constrained so that it can move only in a vertical direction and so that the centre of gravity of the weight remains vertically above the head cap.

Where a means other than a dead weight is employed, the actual force applied to the head cap shall be continuously measured and recorded during the first and th lifting cycles to ensure that the force is within the specified tolerances.

This may be achieved by using a suitably loaded vehicle or by using an arrangement such as that shown in Figured. The head cap load at this lowered position should be as close as possible to zero but the compression spring must be fully extended to fill the available space between the weight and the force measuring device.

This is the initial operating force. This is the operating force after conditioning. Note whether any overtravel occurs. This height represents the lowest position in the lifting cycle for all subsequent rig testing specified in this Paragraph.

For rig testing, lower the head cap to the height specified in Step a. This height represents the lowest position in the lifting cycle for all subsequent rig testing specified in this Paragraph C4.

The object of the test is to measure how far the head cap travels after stopping action has been taken while the jack is being lowered under load.

The fixed reference mark shall be located to coincide with the mark on the jack when the head cap is at the midpoint of its travel. Alternatively, a suitable rig using a weight of appropriate mass to apply the force may be used.

This height is H2. Do not exceed the operating force specified in Clause 6. These standards are developed through an open process of consultation and consensus, in which all interested parties are invited to participate. Through a Memorandum of Understanding with the Commonwealth government, Standards Australia is recognized as Australia’s peak national standards body.
