NO. 307 Sand Rammer Foundation Tester | |||||
This accessory is used to check the ramming energy of a sand rammer. Consists of 24 calibrated, steel impact rings, an anvil and a micrometer. Testing procedure is simple: The anvil is placed on the sand rammer beneath the plunger head and a single steel impact ring set vertically on the anvil. The crank of the sand rammer is turned three revolutions, subjecting the ring to three rammer blows. When removed, the height of the compressed ring is measured to the nearest one thousandths of an inch with the micrometer.
Should this reading fall outside the prescribed range furnished with the checking rings, all items listed in the Sand Rammer instructions are checked and adjusted until the unit will compress a ring to within the specified tolerance. Replacement rings (No. 307-3A) may be ordered. Specifications: Net weight: 2 lb (0.9 kg) Rings are used to calibrate Sand Rammers: No. 315, No. 754-A |
