Slide Plate on Constant

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.

120 3/8" Long Custom Variable Spring Supports with Four Individual Coils

120 3/8" Long Custom Variable Spring Supports with Four Individual Coils

These variable springs are custom designed from carbon steel material. The springs are fabricated with extra long housings to allow for a pre-compression lower than the standard. This ensured that the starting (cold) load of 26,745 lb. could be achieved. The springs are designed for a movement of 5.55″ downward, which would produce an operating load for each assembly of 38,305 lb. These springs are to be utilized in pairs together with a 22″ riser clamp to produce a 407″ total pipe hanger assembly length and an overall combined operating load of 76,610 lb.
