H-4150

Motorized

Sample Ejector

General

The H-4150 and H-4150.4F motorized sample ejectors are designed to remove samples
from molds and tubes. They feature a 5-ton capacity motorized hydraulic pump and ram
assembly and incorporate extended upright rods in order to accommodate both
standard 4” or 6” asphalt compaction molds, as well as the taller gyratory compaction
molds.
Overall dimensions excluding pump 13” W x 6” D x 29” H (330 x 152 x 737mm).

The Model H-4150 consists of the following main components:

1.1 H-4150.2 - Pump Assembly.

1.2 H-4150.21 - Frame Assembly.

1.6 A plastic plate with collar.
A set of 4 ejection disks and 3 ejection rings.

Set Up

Remove the rubber covers from the quick disconnect fittings on the end of the
hose and on the cylinder.

Connect the hose to the cylinder by screwing together the quick connect.
Be sure to relieve the pressure in the hose by putting the lever on the pump valve

to the “return” position before connecting hose to cylinder.
Plug pump into correct outlet for the pump power rating.
Activate the pump with either the button in the handle or the button on the wired

remote.
If you activate the pump with the lever on the pump valve in the “return” position

it will push the sample out and the cylinder will immediately retract when the
button on the pump is released. To keep the cylinder in the extended position
move the lever on the pump valve to the “hold” position.

Operation

Place and attach the proper size ejection disc for the mold or tube onto the jack piston
rod and insert the matching ejection ring into the top casting using the key notches to
retain it by twisting approximately 30 degrees.

Place the mold with sample into the disk and raise the jack to bring the mold into
engagement with the top ring. Continue applying force by operating the jack handle
to push the sample from the mold.

Maintenance

Inspect the oil fill hole and maintain oil level to the bottom of the screw hole with jack in
the upright position. Use hydraulic jack oil available in local auto supply stores.
