The Interface range of flame proof load shackles is designed for lifting and weighing in rugged or harsh environments, and also meet the requirements for operation in Zone 1 and 2 hazardous areas. The shackle pins are forged from high tensile stainless steel and are machined to an exacting specification. The basic shackle uses the Crosby G2130 (1 to 25MT or 2.2K to 55.1K lbf) and G2140 (40 to 400MT or 88.2K to 882K lbf) series.
This range of flame proof load shackles is proof loaded to 150% of the normal rated load, and is available in a range from 3.25 to 400 MT (7.17K to 882K lbf). The ISHK-A is internally gauged and the whole instrumented area is sealed to IP67 to protect it in service. They are simple to install and are available in standard shackle sizes. As an option, a rotating bobbin can be supplied to centralize the load and to minimize any point-load effects when the shackle is placed under load.
We are also always happy to discuss any special requirements that can be accommodated.
The flame proof series can be supplied on its own or combined with our extensive range of instrumentation to provide a complete load monitoring package. Larger shackle sizes up to 1500MT (3306K lbf) are also available using GN Rope shackles.
