Compactor Types
Stationary Compactors
Stationary compactors are bolted or welded to a
permanent surface and used to pack waste material
into a compaction container or trailer. Once full, the
receiver container is hauled to a landfill to be emptied.
Stationary compactors are available in several design
grades:

Heavy Duty Industrial

• Recommended for installations requiring one pull
per day or more
• Extra heavy duty construction and dual cylinder
rams provide long life performance and maximum

packaging material, wooden skids and crates, and

Precrushers are a specialized stationary compactor
unit used in conjunction with an industrial or heavy duty
industrial compactor.

volumes of bulky and difficult to compact dry waste

Self-Contained Compactors

The precrusher gate mechanism is an integral part of

the precrusher unit and NOT an add-on feature to a
stationary compactor. Due to the tremendous forces
generated, the integrity of the equipment and the safety
of the operator is questionable when the precrusher
gate is designed as an add-on feature to a compactor A self-contained compactor is designed to handle
high volume liquid applications. The compactor is
permanently attached to the container and mounted on
its understructure. When the container is full, the entire
unit is loaded onto a roll-off hoist truck for transportation
to the landfill.

The volume of liquid that can be held is determined

by the height of the sump on the compactor and the
quality of the seal on the container door.
Note: roll-off hoist trucks use a variety of designs to
load and secure the containers for transportation. The

 Ideally, the ram should ride on the compaction chamber
floor. This uses the entire surface of the floor to support
the ram and resist waste material build-up between the
ram and the compaction chamber floor.
Engineering shows us that the ram riding on the floor
will not cause any significant loss of forward force
from the friction between the ram bottom and the
compaction chamber floor. Once the ram is moving,
the coefficient of friction is the same whether the
supporting area is one square inch or one-thousand
square inches keeping weights and materials
consistent.

Compaction Chamber Floor Plate

Steel used in construction of the compaction chamber
floor should be high quality and relatively flat. SP
Compactors use AISI grade steel A36 for commercial
units, and a harder steel AISI 1045 for all industrial ad
precrusher units. (AISI 1045 steel is considered work
hardening, which means that the steel actually gets
harder the longer it is used.)
It goes without saying that higher grades of steel are
stronger, more consistent in strength throughout, and

NOT be as hard as the chamber floor steel. Both plates
will last longer if the two steel plates working against
each other are of different hardnesses. Forward force lost between a ram which rides on the floor
and one that is suspended above the floor is negligible.
Ram Guide System The actual guide system consists of a number of
adjustable wear blocks at the back of the ram and

will slowly wear before the steel wall or support it is in
contact with wears.
The principle is to give the guides a good surface to
work on so that the ram movement remains stable. Any
movement side-to-side or up-and-down will cause the
compactor ram and compaction chamber to wear more
quickly; shortening the life of the compactor.

Design Considerations: Construction Materials & Design
Hydraulics
Cylinders
A hydraulic cylinder is measured by its bore (the inside Many compactor models use two hydraulic cylinders
diameter of the casing), rod (the outside diameter of which are crossed. The cylinders are mounted on each
the movable rod), and stroke (the length the rod is side of the compactor and opposite sides of the ram.
able to move). The force that the cylinder can exert is
determined first by the size of the bore; a larger bore This design helps to shorten the overall length of
cylinder is capable of exerting greater forces. The the compactor and is useful in certain applications.
diameter of the rod determines whether or not the rod
can withstand the force it is generating. A larger rod
means a stronger cylinder.

However, one notable shortfall is that crossed cylinders

do not generate as much force as straight push
cylinders of the same size. A crossed cylinder pushes
at an angle to the ram movement which reduces the
forward force of the ram. Cylinders with greater final
angles to the ram face will have less final forward
thrust on the ram.
Oil
Hydraulic oil is the lifeblood of the compactor. Clean
high-grade oil should be used in the power unit at all
times. Lower grade oils can break down faster and
cause components to wear out more quickly. A pour
point of -30° F is a must for cold climates. Oil heaters
and coolers are available for extreme conditions.
Some compactors are equipped with one cylinder
(single cylinder models); others with two (dual cylinder
models). Generally, two cylinders of the same size will
have twice the force of one, and they can be spaced
to spread the force generated against the ram face
more evenly than one cylinder pushing in the middle.
Larger compactors with wider ram faces tend to have
less side-to-side ram movement when they employ two
cylinders.
In addition, longer cylinders must be supported to
assure against sagging or bending from the force they
generate, and their own weight and the weight of the oil
inside when they are fully extended.
