COMPONENTS: the designers, not least is the issue of foundation settlement and how to deal with it.
With many construction projects now taking the form of Engineering, Procurement, and
Construction (EPC) or Design and Build, it is the Contractor’s responsibility to develop the

most cost effective solution that meets the client’s performance specification.
To design a foundation that will not move is unrealistic and ultimately not cost effective.
The Gantrail re-levelling and re-alignment system offers designers an economical solution

amounts of settlement to occur post installation.
If the crane rail system begins to move outside of operational tolerances, it can be re-
levelled or re-aligned with minimal downtime.

This system is designed for rails with an approximate foot width (F) of 150mm, but can be used for a wider selection of rails than
illustrated. This may result in a loss of adjustment from the clips. Please contact GANTRAIL to discuss other possible rails.

The NEW Gantrail 1 Series clips and Mark 8 pad are an evolution of the already proven and highly
successful 9 Series clips and Mark 7 pad. The development of these new products has made use of finite
element analysis and a wide range of testing methods, to provide products which offer real world benefits.
The creative based engineering design process has been guided by in-depth research, drawing on our
years of experience and knowledge. We are proud to offer a new product range designed to suit our
customers’ needs with new features and performance benefits for the future of crane rail systems.
New 1 Series Clips: consists of the 1116/15, 1216/15, 1120/21 and 1220/21
FEATURES BENEFITS
• Increased lateral adjustment • The increased range of adjustment makes installation of the rail easier, whilst also helping with routine
maintenance adjustment.
• Increased side load capacity • Improved side load capacity to suit more arduous crane applications.
• New captive bolt • The introduction of several new features has meant that the captive bolt torque has been increased. This
allows the use of impact wrenches, whilst increasing the clips’ performance. The higher torque values have
been achieved by:
• Manufacturing the bolt from a higher grade material.
• Introducing a square shank which makes loosening of the bolts easier for maintenance purposes.
• Using an oval shape bolt head increases the contact area between bolt and base.
• Increasing the edge radius at the interface of the square shank and head of the bolt, the stress
concentration is reduced.
• Reduced mounting width • The new clips will fit narrower girders and soleplates, offering material cost savings.
• New clip cap and base design • Both parts have been optimised by adding and removing material where required to improve strength and
performance.
• Redesigned profile • The flutes or grooves now exit the sides of the pad so that as the flutes 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, further improving resistance to rupture.

THESE ARE ONLY TYPICAL EXAMPLES. There are a number of possible arrangements and GANTRAIL can advise on these for your specific application.
INSTALLATION INSTRUCTIONS:
The installation method should ensure that the soleplates are level with the base of the rail. This is best achieved by levelling the rail and then
bringing the sole plate plus pad, up to meet the bottom surface of the rail over its full area. Gantrail can advise as to suitable methods and supply.

gap between the rail ends is filled with melted welding electrode. The bottom

after each run. When this is complete, copper moulds are placed to each side ASME IX QUALIFICATION

The gap is then filled with weld metal in a continuous welding process. The

The benefits for continuously welded rail are considerable but they require the rail to be welded on
site. Most crane rails are supplied in lengths of 12 metres. Typically rails may be welded into lengths
of 300 metres or more with no expansion joint. The rail cross sections are large and the metallurgy;
with high carbon and manganese content; make welding difficult.
Several methods have been developed that can readily be used. Aluminothermic rail welding is well
established and is the most commonly used process for site welding of railway rails in many parts of
the world. It is equally applicable to the site welding of crane rails.
METHOD
The rail ends are left cut square and set a distance
apart. The volume around the ends is enclosed with a
refractory mould and sealed. The mould is supported by
reusable tooling. The gap between the two rails and the
mould are preheated with the prescribed burner for the
required time. Then the disposable crucible is placed
above the rail and it is ignited. The casting process from
then on is automatic. After a set time the tooling, the
remains of the mould and excess metal of the runners
and risers are removed.
