Weighing Cradles are used in suspension weighing of samples for specific gravity or bulk density determinations. Small, Large, and Mega models accommodate a variety of sample and pycnometer sizes and shapes. The cradles with samples are immersed in water and suspended by wire attached to the weigh-below fixtures of scales or balances. Suspension wire can be sourced elsewhere. See separate listings for suitable scales or balances, weighing tables, and other accessories.
SGA-119 Small Density Weighing Cradle is formed from heavy stainless steel and holds various Marshall, Gyratory, or other material specimens. It is adaptable for multiple specimen types.
SGA-125 Large Cradle accepts SG-16A Vacuum Pycnometer Canisters, Aggregate Density Baskets, Marshall or Gyratory Compaction specimens, cores up to 6in (152mm) and other large samples. The Cradle tilts back when loaded for stable weighing of samples. Rugged welded stainless steel construction.
SGA-135 Mega Cradle has a design similar to the Large unit but accommodates even larger specimens and pycnometers. Accepts the HMA-260 Small Aggra-Washer Drum when used with the HMA-262 Vacuum Lid for Rice tests, the SG-18A 4,000g Vacuum Pycnometer, and other over-sized samples. Vertical clearance is 12.5in (318mm).
