Humboldt H-4156M CBR-Specific Load Frame - Manual (Page 5)

Operation
Control Panel
The control panel is situated on the front left hand side of the machine base.
Preset Speed:
H-4156M:
.05 in/min. (1.27mm/min.)
H-4156M.4F (60Hz): .05 in/min. (1.27mm/min.)
H-4156M.4F (50Hz): .04 in/min. (1.00mm/min.)
Direction of Travel
It is necessary to ensure that the direction of the platen (up or down) has been
correctly selected. The platen travel direction switch has three positions: up, off,
down. Before changing travel direction, you must first switch to the “off” position
and pause for a second before changing travel direction.
Maximum Travel Limits
The maximum up travel limit occurs when the loading screw extends beyond the
reach of the drive gear and remains there – it is not indicated by a light. The
down travel limit is indicated on the control panel with a red indicating light.
The machine will stop operation in that direction when this light is illuminated.
The maximum travel of the platen is 3.50" (88mm).
Load Ring
When a load ring is used it can be attached directly to the cross-beam using the
3/4-16 x 3" long bolt.
Maximum Load
The Marshall Compression and Testing Machine is rated at 10,000lbf (or 50kN).
Penetration Measurement
Can be measured with the H-4178 Penetration Piston and Stud and the H-4158.1
Dial Indicator, which is mounted to the penetration piston by H-4178BR Dial
Indicator Bracket. These items are included with your H-4156M CBR-Specific
Load Frame.
You must use the
toggle switch to stop test.
The machine does not
stop automatically when
the stability load is reached.
