AS 1418.1-2002 Cranes, Hoists and Winches Part 1: General Requirements
AS 1418.1-2002 Cranes, Hoists and Winches Part 1: General Requirements specifies the general requirements for cranes, hoists, winches, and their components, and appliances intended to carry out similar functions, as defined in AS 2549. It does not include powered industrial trucks as defined in AS 2359.The term ‘crane’ used herein applies to a crane, hoist or winch as appropriate.
This Standard was prepared by the Standards Australia/Standards New Zealand Committee ME-005, Cranes, to supersede AS 1418.1—1994.
Requirements that apply to more than one type of crane are included in Part 1: General requirements. Any requirements that apply to only one type of crane should only appear in the specific part for that crane and not in Part 1. Some requirements have been deleted from this Standard and are being moved to their applicable Part.
The Commonwealth, State and Territory governments may choose to incorporate this Australian Standard into their laws and regulations. The exact manner of incorporation will determine whether the whole document is incorporated or whether specific sections or provisions of the Australian Standard are incorporated.
This Standard deviates from ISO 11660.1 regarding access requirements for safety reasons. This revision includes the following changes:
- The maximum temperature of touchable surfaces is now 55°C.
- The term ‘safe working load’ has been changed to ‘rated capacity’ and other uses of
- the word ‘safe’ have been avoided due to the legal significance placed on the word.
- Reference to approval by the relevant authority has been removed to reflect the current regulatory environment.
- Tear-out/tear-off forces for cranes equipped with magnets or grabs have to be taken into consideration.
- There is a new method of calculating the hoisting factor (φ2), which is taken from DIN 15018.
- Out-of-service wind loads are now considered additional loads instead of special loads.
- Transport loads have to be taken into consideration where the crane is transported during its life.
- The design of monorail beams has been moved to a new Part 18: Runways and monorails.
- The factor of safety against drifting during operation has changed to 1.5.
- The design life of mechanisms may be less than 10 years provided this is documented.
- In determining the group classification of mechanisms, an adjustment to an equivalent number of running hours is allowed after the load spectrum factor has been set.
- Requirements for gearing have been expanded. Requirements for hoisting, travel, and traverse motion brakes have been expanded.
- A minimum worn wheel flange thickness has been defined.
- Hookbolts used for rail fastening are required to be ductile.
- Detachable parts are required to be designed for safe assembly and disassembly.
- The attachment of hooks directly attached to structural members is required to be designed such that no bending moment is experienced by the hook shank.
- Some requirements for counterweights have been added.
- Requirements for controllers have been revised.
- Requirements for limit switches have been revised.
- Motor protection requirements have been revised.
- Mention is made of electromagnetic compatibility (EMC) and phase sequence protection.
- Extra requirements for cranes with lifting magnets have been added.
- Emergency egress requirements have been revised.
- Requirements for installation of cranes in hazardous areas have been revised to interface with recently revised applicable Standards.
- Requirements for operators and maintenance manuals have been added.
