These custom designed constants will be utilized for a heavy load of 109,000 lb. They are designed for a downward travel of 1 1/2″. In order to support the heavy load and low take-off, the constants are designed with an inner and outer spring coil with the outer coil measuring 56″L with a 18 3/4″ O.D. These U-Type constants are fabricated from A36 carbon steel with a hot-dipped galvanize finish.
The dimensions of the constant are 31″H x 90″L x 32″W. The image above shows a PTFE, 25% glass filled slide plate on top to reduce the friction between the constant load flange and the structure above the support. The constant also includes slide plates between the table and the frame of the constant to reduce the friction on the table and improve constant deviation.
