Forging Crane Clip Clip
ZY has been providing engineered, adjustable soft-mount crane rail
solutions for all types of crane tracks and runways for
rail-mounted equipment in the toughest environments and highest
The extensive Zhongyue clip range can accommodate nearly every rail
profile produced in the world, including DIN Rail, MRS Rail, ASCE
or “T” Rails and US Crane Rail sections, used either with or
without crane rail pad. Two main clip types are available, based on
the fixing support: either welded-base or through-bolted. Zhongyue
offers clips for use with both imperial and metric hardware, and in
both single-bolt and double-bolt configurations for all types.
Zhongyue crane rail clips maintain the rail lateral position but allow for needed longitudinal movement through the use of the
vulcanize-bonded rubber nose. The nose helps absorb the energy of
vertical deflection caused by wheel passes.
Zhongyue crane rail clips are manufactured throughout the world, with primary manufacturing
in North America and Europe.

Crane Rail Clips and Bolted Clips
Zhongyue self locking crane rail clips are designed to align and
securely fix the rail. The elastomer ‘nose’ applies a controlled
force to the rail to restrain excessive movement.
They must :
- fit the support structure
- fit the rail
- carry the horizontal forces from crane wheels, perpendicular to the
Size for size welded clips give a stronger installation but bolted clips are often more convenient.
- Find or estimate the horizontal force to be carried by the clip. It
is assumed that all of the load from one wheel will occur at one
clip. If the load is not known it may be assumed to be 15% of the
vertical wheel load.
- Choose the style of clip you require – bolted or welded. These are
identified with their respective strengths.
- Find the dimensions of the foot of the rail to be used.
- Check that the selected clip will fit the installation.
The choice between bolted clips and those with welded lower
components is often based on industry practice and preference. The
bolted clips are economical but size for size they are rated
significantly lower on load carrying capacity. Thus heavy duty
industries such as steel and aluminium manufacture tend to use
welded base 8 or 9 series clips whereas lighter applications such
as industrial buildings and high bay warehouses use 3, 6 or 7
series clips that are fixed by bolting. WE are always happy to give
guidance on this matter.
It is assumed that grade 8.8 bolts will be used. If welded studs or
grade 4.6 bolts are used then their strength is only taken as 40%
of grade 8.8 bolts.
