Introduction
Product Description— H-4156M
The Humboldt H-4156M CBR-Specific Load Frame Set has been designed
to provide labs with a single-speed load frame specifically designed to do
California Bearing Ratio (CBR) testing. The machine has a one-speed motor with
a reversing switch that produces a uniform vertical movement of .05" (1.27mm)
per minute, ASTM D1883, AASHTO T193. The maximum piston travel is 3 1/2"
(88mm). The H-4156M is sold as a CBR-specific set and includes:
(1) H-4156M CBR-Specific Load Frame (115 VAC 60 Hz, 1 phase)
(1) H-4454.100 Load Ring, 10,000lbf (50kN)
(1) H-4158.1 Dial Indicator, 1.000" x .001"
(1) H-4178 Penetration Piston with Stud
(1) H-4178BR Dial Indicator Bracket
Product Description— H-4156M.4F
The Humboldt H-4156M.4F CBR-Specific Load Frame Set has been designed
for use in 220 50/60Hz applications and those who need to test CBR to the
BS 1377: Part 4 Standard of .04" (1.00mm) per minute. When operated at 60Hz,
the H-4156M.4F complies with the ASTM D1883 Standard; and, when operated
at 50Hz it complies with the BS 1377: Part 4 Standard. The H-4156M.4F also
includes the following items:
(1) H-4156M CBR-Specific Load Frame (220 50/60Hz, 1 phase)
(1) H-4454.100 Load Ring, 10,000lbf (50kN)
(1) H-4158.1 Dial Indicator, 1.000" x .001"
(1) H-4178 Penetration Piston with Stud
(1) H-4178BR Dial Indicator Bracket

General Information
Inspection
Your CBR equipment was thoroughly inspected before it was shipped and
should be ready to operate as soon as you have completed the set-up
procedure.
Notify Humboldt Mfg. Co. or your local agent and file a claim with any carriers
involved if you find any damage to the machine. Unpack all of the equipment
carefully to prevent loss of small items or manuals.

Power Supply
110 VAC 60 Hz 1 phase (H-4156M), 375 watts
220 VAC 50/60 Hz 1 phase (H-4156M.4F), 375 watts
Check to make sure your machine has the correct voltage for your local supply.
Power Cord
The H-4156M machine is fitted with a molded vinyl-grounding plug, while the
H-4156M.4F is supplied without a plug allowing you to fit it with the correct
plug for your application.
The cord is made of three conductors:
(American color-coding) (International color coding)
Green Ground (Earth) Green/Yellow Ground (Earth)
White Cold (Neutral) Blue Cold (Neutral)
Black Hot (Live) Brown Hot (Live)
Fuses
The CBR Test Machine uses a slow-blow fuse that is fitted into the left side of
the machine. The replacement part number is H-1339.13.
Initial Installation
Remove the packing list and verify that all parts have been received. Normally
you will receive one crate comprised of compression frame and a calibrated
load ring (H-4454.100) 10,000lbf capacity, and accessories for CBR penetration.
Set the machine base up at the place it is to be used in the laboratory and
then check that it is level by placing a spirit level on the platen. If it is not level,
adjust the feet of the machine.
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).
IMPORTANT
You must use the
toggle switch to stop test.
The machine does not
stop automatically when
the stability load is reached.
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.
Load Ring Calibration
Your H-4454.100 was calibrated before leaving the factory. Periodically you
should have it re-calibrated. Humboldt provides calibration services for
these load rings, please contact us at: 1.800.544.7220, 1.708.456.6300,
1.708.456.0137 fax or hmc@humboldtmfg.com.
Maintenance
The machine and transducers should be kept clean and the machine should not
be over lubricated. Light oiling with synthetic instrument oil at most is required
on exposed spindles and threads.
