Gantry, Crane design
Gantry, Crane design
(OP)
Hi Fellows
I am designing a Gantry for OH&S purposed for a dam, in-case someone injure and easy to lift for succor.
The client said design for 100kg weight capacity.
I would like to ask is there any min. load requirment for designing a gantry for lifting people? and which Australia Standard is proper to use, AS1418?
Thanks for your help

RE: Gantry, Crane design
The AS 1418 suite of standards is the correct choice for the design of cranes.
The proposed 100kg capacity sounds a bit light. A large man with sodden clothing and boots, together with mass of the harness, rope, will result in a lift of somewhat more than 100kg. By comparison, AS1170.1 uses an unfactored concentrated live load of 1.4kN on roofs and roof elements to account for a force imposed by a person (ref. Clause 3.5.2).
Note that you will need to factor this load more than you would for an inanminate object, since personnel safety is involved. For example, AS 1418.17-1996 Cranes (including hoists and winches) - Design and construction of workboxes uses a design load factor of 2.5 times the static load to take account of the hoisting factor and that personnel are being lifted.
