The Gantrail GlideRail System

ShortRail Section

The short rail is a section of rail positioned either side of the boom hinge joint (landside, seaside).

Short rails come in a range of lengths welded to the end of the long rail and clamped into position in 3 directions to limit movement.

The staggered finger joint at one end is positioned directly inline with the staggered cut in the boom hinge joint.

This allows the GlideRail system to move apart when the boom arm is raised for container ship docking.

GlideRail in motion: Short Rail Design Detail

The short rail profile is specially machined to reduce damage to the rail edge & around the L-shape joint, typically a problematic area for OEM boom hinge designs.

These core parts of the system help create a level running surface for the trolley wheel to operate smoothly time & time again and allow the specially design short rail profile to handle the load extending the life of the system.

GlideRail in position: GlideRail Patented Clamp

The GlideRail clamp is specially designed around concentric movement, this allows for a large range of adjustment, a strong clamping force & limits bolt fatigue enabling longevity of the product’s lifespan.

Key Design Features:

• Concentric faces enable the cap to adjust for varying rail foot heights
• Large angled curved surface contact area improves clamp slip
• Downforce is generated by the concentric movement between cap & base
• Clamping force stays perpendicular to bolt alleviating bending stress leading to bolt failure on OEM clamps
• Concentric captive bolt rotates with cap to aid perpendicular movement for clamping
• Locking flange nut helps limit retightening occurrences

GlideRail in position: GlideRail Clamp Components

The GlideRail clamp is specially designed to solve the current in market OEM system problems. Each key feature below combines to create part of the GlideRail system solution.

Key Design Features:

• Locking flange nut – designed to reduce retightening
• Slot for adjustment – designed to aid height adjustment
• Concentric cap design - designed to work with concentric base for height adjustment
• Large curved & angled contact area - designed for larger surface coefficient
• Concentric base design – designed to work with concentric captive bolt to allow perpendicular movement
• Large curved contact area for clamping – larger curved surface area
• Concentric captive bolt – designed to move perpendicular with the clamping force reducing stress on the bolt
