1 In order to make reliable connection, each of the bars on the node and end splice

joint, the number should not be less than two permanent bolts . However, according

to experience , for the combination of components lacing their ends can be connected

to a bolt .

2 direct withstand dynamic loads ordinary Track Bolts connection should double nuts

or other effective measures to prevent the nut loosening adoption. For example the

use of a spring washer , nut or screw or welded shut and other methods.

3 due to the C -stage bolt hole wall has a large gap , is appropriate only connected

along its axial direction by pulling the rod . Withstand static load of the

secondary structure , the connection and the structure of the temporary fixing

member detachable connection with the installation , also available Class C Track

Bolts shear . But in an important connection, for example : braking or connecting

beam crane beam flanges and column , because the horizontal support beams passing

brake reaction force , but by repeated dynamic loads , shall not use C-Class Track

Bolts. The connection between the support columns and columns , and the connection

between the columns in support of the flange of the crane , bear repeated because of

the level of braking force and the power rail , priority should be made of high

strength Track Bolts link.

4 bar gauge the direction of the tension along the Track Bolts connecting the end

plate should be suitably strengthened its stiffness to reduce the adverse effects of

prying on the tension capacity of the bolt.
