RailLok™ Weldable Clip General Specifications - Gantrex

RailLok TM Series
WELDABLE CLIP
General Specification
This general specification describes the revolutionary, patent pending RailLok TM series of weldable rail clips which
incorporate a “double wedge design” feature and bolts with a “square shank base”.
It is an evolution of the GANTREX ® crane rail soft-mounting system which consists of a range of redesigned weldable
crane rail clips and steel reinforced rubber pads to address today’s unique problems. Individual data sheets on the
various GANTREX ® clips and pad profiles provide details of the unique characteristics and geometry of each product.
GENERAL CHARACTERISTICS
All RailLok TM series clips are specifically designed for the mounting of crane rails, with or without pad.
A full range of weldable clips is available to the designer, offering both cost efficiency and the very best technical
solution for the installation.
All RailLok TM clips consist of two interacting components which allow easy lateral rail adjustment and, once correctly
installed, are self-locking and self-tightening. A controlled vertical force is applied to the rail foot through a synthetic
rubber “nose” which is vulcanize-bonded to the clip upper component.
The new “double wedge design” clip feature allows more efficient and rapid installation, as the upper component,
by design, keeps a tight contact with the rail foot as the bolts are torqued and the nose compresses. Locating the
rail by “hammering” is no longer required. In addition, impact wrenches can be used to accelerate the installation
process because of the newly-designed screw type bolt with a “square shank base”.

TECHNICAL ADVANTAGES OF THE NEW RailLok TM CLIPS
New Features
RailLok TM Series
WELDABLE CLIP
General Specification
• Contact between the clip upper component and rail is enhanced during bolt tightening and nose compression
because of the “double wedge design”.
• Does not require hammering of the clip to contact rail.
• Use of impact wrench speeds up the installation process.
• Larger lateral rail adjustments.
• Higher resistance to lateral loads using lighter components.
• Compact design for use with narrower supports and to avoid guide roller interference.
All old features have been maintained
• Simple and positive lateral rail adjustment of up to 20 mm (3/4") depending on type of clip.
• Self-locking and self-tightening features through wedging action.
• Higher resistance to lateral loads through careful selection of clip component materials.
• Controlled vertical force applied to rail through synthetic rubber “nose”:
• Minimized crane runway maintenance and down time.
CLIP SELECTION
The following information must be available in order to select the correct GANTREX ® clip for your installation :
• Rail designation (e.g. 175 CR, A 120).
• Thickness of pad or wear plate under the rail.
• Maximum side thrust per wheel.
• Support width, namely girder top flange or soleplate.
• Lateral adjustment required.
• Vertical clearance tolerances where guide rollers are used.
Please consult GANTREX on any questions regarding selection.
INSTALLATION INSTRUCTIONS
See data sheet on specific clip for product details.
Refer to “Installation and Suggested Weld Instructions” for detailed information on use.
A standard option on all GANTREX ® clips is protection against corrosion in the form of electro or hot-dip galvanizing.
The lower component is first welded to the plate or girder before the entire system is galvanized. The clip bolt
assemblies come standard as hot dip galvanized.
If painting is required, please consult GANTREX before using mineral-based solvents, as they may adversely
affect the coefficient of friction between components.
Do not use cleaning fluids or protective coatings which contain ketones or similar chemicals, as they may seriously
damage the rubber nose.
We reserve the right to discontinue or change specifications or design at any time without prior notice
and without incurring any obligation whatsoever.
