Steel Reinforced Resilient Pad Mark 8

The Gantrail Mark 8 pad is an evolution of the already proven and highly successful Mark 7 pad. The use of Gantrail Mark 8 Crane Rail Pad between a rail and its support substantially improves the performance of heavy duty crane tracks. Cranes apply very high forces to the structures on which they are mounted. The pad significantly reduces the stress between the rail and its support. The Gantrail pad is one of the three key ingredients in achieving a reliable track:

• Resilient Pad 
• Strong, adjustable clips
• Continuously welded rail

Features:

• The Gantrail MK8 pad has a completely redesigned profile including a re-orientated flute pattern on its top surface.
• The fluted top surface results in a two stage stiffness characteristic. On loading, the voids in the top allow the Gantrail clips to pre-compress the pad a small amount. On increasing the wheel loading, the voids are reduced in size and the pad becomes stiffer. This ensures that the rail is not over stressed.
• The flutes now exit the sides of the pad so that as the voids are reduced in size during loading, any fluid is flushed out carrying with it debris and other contaminants.
• By orientating the flutes at an angle of 45 degrees, the resistance to lateral tearing induced by rotational forces from the rail, has also been vastly improved over the previous longitudinal flute design. This has the added advantage of improving the cross sectional area of the rubber along the edge of the steel reinforcement, improving resistance to rupture. 
• The pad is reinforced with a high strength steel strip to ensure high lateral stiffness and prevent movement from below the rail.

Together with Gantrail we can supply standard design details and technical information in support of all crane rail applications.
