3.1 Unpacking
Go to
and watch a video on how to unpack the machine.
Each Universal Calibrating Machine is assembled and tested at the factory prior to shipment. The calibrating
machine is packed completely assembled, as a unit, in a single crate. The lower yoke platen is bolted to the
lower machine platen to form a rigid assembly for shipment, and the hand pump assembly is disconnected
from the jack and attached separately to the shipping crate.
The uncrating procedure is straightforward. With the crate in a horizontal position, remove the packing materi
-
al from the crate, being careful to check for small parts and accessories that may be packed with the calibrating
machine, including the hydraulic hose.
Caution: Before lifting, ensure the unit does not exceed the capacity of the lifting equipment.
3.2 Installation
Installation consists of setting the machine in place on a smooth, flat surface, and leveling the machine by
means of the adjustable feet, using the circular level as an indicator. The 10,000 lbf (50 kN) capacity machine is
normally placed on a bench or sturdy table. Larger machines are usually installed adjacent to a bench or other
suitable work surface to which the hand pump can be fastened. Note: Selection of a location where an even
temperature prevails will greatly facilitate calibration.
After the machine has been installed in position, remove the bolt that holds the lower yoke to the lower
machine platen. Next, operate the hand pump to extend the ram of the hydraulic jack approximately 1/16 to
1/8 inch. Loosen the tie bar locking collars and raise the lower yoke platen until the lower surface of the upper
yoke platen is within 1/8 inch of the shoulders of the tension tie bars.
Note: Be careful not to run the upper yoke platen up against the shoulders of the tension tie bars as this may
damage the calibrating machine.
Next, slide the locking collars down the tension tie bars to the upper machine platen, and firmly tighten the
locking collar set screws. Now raise the upper yoke platen so there is sufficient space to insert the force stan
-
dard between the hydraulic jack and the upper machine platen.
Note: Be careful not to run the upper yoke platen against the stops near the end of the threads of the tension
tie bars as this may damage the calibrating machine.
