In all cases the type of application and environment will determine which type of lifting shackle you use.
General Lifting Applications
All Petersen PH shackles have a specific design for a specific application. The Petersen PH shackle range are designed and manufactured for general lifting applications such as:
- Coargo lifting in marine environments
- General industrial lifting
- Lifting in non-corrosive environments
PH shackles are heat treated to between condition H1025 and condition H1075 to achieve the optimum balance of mechanical properties and resistance to corrosion: in this state PH 17/4 closely approaches stainless types 302 and 304 for most corrosion agents. If corrosion resistance is of greater importance then please refer to the Petersen E Type Shackles detailed below.
Lifting Applications in Natural Conditions
Petersen stainless steel E Type shackles should be used in applications where corrosion resistance is of significant importance. Stainless steels are possible solutions to corrosion problems and are ideally suited to natural (water, city and landscape atmospheric) conditions. Usual applications include:
- Offshore rigs
- Water sewage plants,
- Children’s playgrounds,
- Submerged water pumps
Petersen stainless steel E Type shackles should NOT be used in general lifting applications where corrosion resistance is not required. For such general lifting applications please refer to the Petersen PH range of lifting shackles. Due to the nature of stainless steel and the possibility of work hardening/stress ageing, we strongly recommend that thorough inspection and maintenance is carried out on a regular basis.
