AS 2615:2016 Hydraulic trolley jacks
6.3 Ease of operation
When the hydraulic trolley jack is tested in accordance with Appendix A, neither the initial operating force nor the operating force after conditioning shall be greater than 450 N. Where operating force exceeds 450 N, Appendix F shall be used to determine the maximum capacity of the hydraulic trolley jack to meet the 450 N requirement.
NOTE: The handle provided for operation of the hydraulic trolley jack should, at the area where the operator applies the operating force, be of such size and shape that undue discomfort is not caused.
6.4 Loss of height under load
When determined in accordance with Appendix B, the loss of height under load shall not exceed 5% of the original height of the head cap above the base plane. At the conclusion of 30 minutes, the loss of height shall not exceed 5 mm.
6.5 Lowering
The hydraulic trolley jacks shall provide an operator-activated, controlled lowering mechanism.
When the hydraulic trolley jack is tested in accordance with Appendix C, the operator shall be able to stop the head cap at a given point during the descent within a distance equal to 5% of the full range of travel of the head cap, without hazard to the operator or damage to the hydraulic trolley jack.
6.6 Overload capacity
When tested in accordance with Appendix D, a hydraulic trolley jack shall—
(a) not collapse or suffer permanent deformation;
(b) not suffer a loss of height of the head cap greater than 5% of the original height of the head cap; and
(c) be capable of lifting its nominated capacity load through one lifting cycle using an operating force not greater than 450 N. Where the operating force exceeds 450 N, Appendix F shall be used to determine the maximum capacity of the hydraulic trolley jack to meet the 450 N requirement.
7 MODIFICATIONS
Any modification carried out or accessories added to a hydraulic trolley jack shall require retesting of the modified jack to this Standard.
