MRS87A Crane Rail, Supplied Across Australia

Inform Rail supplies MRS87A crane rail for heavy duty crane applications across Australia. MRS87A is a tall, near-square crane rail section, 152.4mm high on a 152.4mm foot with a 101.6mm head, designed for large crane wheels operating under high vertical loads in port and heavy industrial environments.

The section traces its geometry to the imperial 6 inch by 6 inch crane rail; older drawings and site records may reference other designations for the same section. With a calculated mass of 86.8 kg per metre it is one of the heaviest profiles in the Inform Rail range, produced in high-strength crane rail grades. Standard supply length is 12 metres, with cut-to-length available prior to dispatch. Matched fastening systems can be supplied to suit the profile and substructure.

FAQ

MRS87A Rail, Common Questions

What is MRS87A crane rail used for?
MRS87A crane rail is used for heavy duty crane applications including port cranes, ship unloaders, wharf cranes and heavy industrial runways. Its tall, near-square section gives high bending stiffness under large wheel loads, and it is a common replacement profile for legacy 6 inch by 6 inch crane rail in older Australian installations.
What are the specifications of MRS87A crane rail?
MRS87A crane rail has a head width of 101.6mm, a height of 152.4mm and a foot width of 152.4mm, with a calculated mass of 86.8 kg per metre and a cross-sectional area of approximately 111 cm². It is manufactured to mill crane rail specifications in high-strength crane rail grades. Full cross-sectional dimensions and material properties are shown on the Inform Rail MRS87A crane rail product sheet.
Is MRS87A the same as the old 6 x 6 inch crane rail?
Yes. MRS87A traces its geometry to the imperial 6 inch by 6 inch crane rail, with a 152.4mm height and foot. Different mills have used their own designations for this section over the years, so older drawings and site records may reference other names. Send your drawing or a rail measurement and Inform Rail can confirm the match.
How does MRS87A compare to 86kg crane rail and the A-series profiles?
MRS87A (86.8 kg/m) and 86kg crane rail (85.5 kg/m) are close in mass but very different in shape. MRS87A is a tall section, 152.4mm high on a 152.4mm foot, giving high vertical bending stiffness, while 86kg rail is a low, wide section 102mm high on a 165mm foot. By mass both sit between A100 and A120 in the DIN 536 range, but neither is a DIN profile. The right choice depends on the existing rail, the substructure and the crane wheel arrangement.
What lengths is MRS87A crane rail available in?
MRS87A crane rail is supplied in standard 12 metre lengths, with other lengths and cut-to-length available on request prior to dispatch. Include your cutting requirements in your enquiry.
Can Inform Rail supply a complete MRS87A fastening system?
Yes. Inform Rail can supply matched crane rail clips, fishplates, sole plates and rail pads as a complete fastening package for MRS87A rail. Send your rail profile, substructure details and any drawings for a complete fastening system quote. No minimum order applies.
