A. Rotary Actuator - rack and pinion style design.
Rack, pinion, and shaft bearings are constantly lubricated by the hydraulic oil for extended life.
Body and caps are made of high quality ductile iron.
Pinion output shaft and racks are made of high tensile alloy steel.
The rotary actuator provides smooth motion throughout the lift cycle, which results in longer cart life with virtually no
cart damage or abuse.
B. Arm bearings are made of a composite material which provides superior compression strength along with self-
lubrication, thus eliminating the need to grease the arm bearings.
C. The THINLINE® lift unit can measure as little as 5” thick from the front of the mainframe to the front of the faceplate
depending on the types of arms used. This allows for easy dumping of large commercial containers without interference.
D. The faceplate is normally at 45 degrees in the dump position and extends 13” to 15” from the back of the mainframe into
the hopper or container opening. This places the cart or barrel 16” to 18” into the truck or container opening thus
reducing any potential spillage of materials.
E. Cycle times for safe, fast, efficient service.
6 - 8 seconds for rear-load and side-load units
8 - 10 seconds for units with 9” and 15” vertical lifts
10 - 12 seconds for stationary, recycling, and double wide, and 24” vertical units
15 - 30 seconds for 3300 series and 3300 series stationary units
NOTICE
Cycle time is controlled by flowrate, as flowrate increases, cycle times decrease.
WARNING
Never exceed the cycle times listed above. In order to avoid injury and maintain manufacturer’s warranty never operate
outside of these recommendations.
F. Recommended flowrates are as follows:
2 to 2 1/2 GPM for 1100 series units

OPERATION INSTRUCTIONS
WI-0124-A
The Bayne THINLINE® Premium Lift System is a high quality durable cart lifter built to meet your industry’s requirements.
To insure the safety of all operators of this equipment, please read this manual carefully before operating the lifter.
FAILURE TO COMPLY WITH INSTRUCTIONS COULD RESULT IN PERSONAL INJURY AND/OR PROPERTY
DAMAGE.
The operating stages ( Figure B-1 ) in the cycle of the cart lifter are as follows:
1. START - The cart to be dumped is placed on the lifter.
2. ACTUATOR DUMP - The rotary actuator cycles to dump the contents of the cart into the box. During this cycle, the
lower hooks automatically rotate to “lock” the cart to the lifter.
3. ACTUATOR REVERSE - The rotary actuator reverses its cycle returning the cart to the start position. The lower
hooks automatically retract to “unlock” the cart from the lifter.
Figure B-1
WARNING
Exceeding the recommended cycle time on any lifter will void the manufacturer’s warranty
The rotational motions of the cart lifter are controlled with the use of a hand valve. Moving the handle on the hand valve in
one direction will cause the lifter to perform the actuator dump stage ( Figure B-1 ). Moving the handle in the opposite
direction will cause the lifter to perform the actuator reverse stage.

OPERATION AND INSTALLATION INFORMATION
WI-0026
The Bayne diverter valve establishes priority flow to the lifter circuit “P1” and “P2” ports and bypasses oil to the “OUT” port,
which typically supplies flow to the remainder of the truck’s hydraulic circuit. This bypass occurs only after the lifter circuit is
satisfied. The priority flow is controlled by the flow regulator cartridge (FR1) (and FR2 in dual applications) in combination
with the differential pressure sensing valve (DPS). This allows the valve to maintain constant flow regardless of changes in
load pressure or volume flow rate. Since both the lifter circuit and bypass flow can be utilized in the operation of the truck
regardless of which pressure is greater, a single pump can be used to supply two circuits or operations.
The lifter circuit flow is regulated and maintained by the flow regulator cartridge (FR1) (and FR2 in dual applications). The
differential pressure sensing valve (DPS), rated for 75 gpm of flow and 3000 psi of pressure, is operated by an internal
spring and dampening orifice (OR) which establishes a pressure drop across the block sufficient to ensure the correct
operation of the flow regulator (FR1). For a dual diverter valve, a second flow regulator cartridge (FR2) is installed in the
“FR2” cavity and a shuttle valve (DSV) is installed in place of the SAE plug in the “DSV” cavity. Once the pressure drop is
established, a precision metered flow is provided to the tipper circuit(s) with additional flow being bypassed to the “OUT”
port.
The operation of the diverter valve does not require the use of a tank line to be run to the “T” port. However, the efficiency
of the block will be significantly increased if a tank line is installed. The logic circuit of the block will manage the flow of oil
returning from the tipper circuit to ensure optimum performance. This is primarily controlled with the sequence valve (PSV)
which is factory set and should not be adjusted. All oil returning from the tipper circuit will normally be regenerated into the
outgoing flow to ensure that the downstream functions are not slowed in any way. When the downstream backpressure
rises to a predetermined pressure, the block will redirect the flow to the “T” port to increase the overall efficiency of the
block and reduce the pressure drop through the block. If the “T” port is connected to a tank line, the oil will be dumped
through the block at a lower pressure. This allows downstream functions to operate at the highest possible pressure when
pressure is being required. If the “T” port is blocked, the oil will be redirected back into the outgoing flow through the check
valve (CV).
A relief circuit for the tipper function is controlled by a relief valve (RV), which is preset to 2300 psi. This can be adjusted to
limit pressure to the tipper(s). This relief valve is more efficient than the relief in the hand valve and will operate with less
noise. It is recommended that it be adjusted to relieve before the hand valve relief. It may also be used to limit the weight
the lifter can dump. This may be beneficial in avoiding damage to cans resulting from overloading. This should be the only
adjustment that the block may require. Any other adjustments should only be made after close consultation with Bayne’s
Engineering Department to ensure proper operation.

Possible Problems
1. The most common cause of valve failure is dirty oil. If debris becomes lodged in the cartridge valves they will
malfunction. Recommended filtration level is between 15 and 25 microns. Many systems filter the oil on the return
side. This does not guarantee clean oil going into the system. It is important to ensure that the tank vent filtration
element is properly maintained as well. Very small contaminants may not cause the valve to stop functioning, but can
cause “stiction” in the cartridges between the body and the moving spool. This can cause improper operation. A slow
moving tipper is most likely the result of contamination in the flow regulator cartridge. A pulsating noise may be the
result of contamination in the differential pressure sensing valve causing it to stick. If any valve malfunctions, remove
and thoroughly clean the valve, being extremely careful not to score or abrade the “o” ring seals or moving parts of
the valve. Be sure that the spool moves freely in the valve body.
2. The flow regulator cartridges (FR1 and FR2) are designed to operate at a designated pressure of 80 psi. This means
that in order for the valve to function properly, a minimum of 80 psi is required from the supply line through the “IN”
port of the valve. This can present a problem on trucks with a dry valve pump system. Normally in the dry (off) mode
of the pump, a flow of approximately 2 gpm at 20 psi is required to circulate through the open center system of the
truck. This is for pump lubrication in the off mode. When the diverter valve is placed in the main pressure line of the
truck, a blockage occurs because of the differential pressure sensing valve needing 80 psi to initially open and allow
the flow regulators function. The path of the lubrication oil is therefore stopped because the valve does not open.
When the oil is blocked, the pump will rotate and cavitate in the lubricating oil, causing heat to build up over an
extended period of time, possibly leading to premature pump failure. To prevent this problem from occurring, a
“bleed line” circuit needs be installed on the truck to allow passage of the lubricating oil back to tank.
3. On front load residential truck applications, several considerations need to be noted. The Bayne hand valve is an
open center valve that allows for the lifter circuit to maintain flow through the hand valve and back to the diverter
valve when the lifter is not being operated. If flow is not maintained through the hand valve, the oil will constantly be
relieving over the lifter circuit relief valve (RV) in the diverter valve, which can cause an increase in operating
temperature. Certain front load box designs allow for the hand valve to be located on the arms of the truck which
keeps the hand valve in the lifter circuit at all times to maintain flow. Most problems occur with applications where the
hand valve is located on the box itself. In this situation, when the operator disconnects the hydraulic lines to the box,
a blocked condition occurs in the lifter circuit. To prevent this problem, the pump must be turned off prior to
disconnecting the box hydraulic lines. Once the lines have been disconnected from the box, it is necessary to
connect the two lines for the hand valve to each other to functionally complete the lifter circuit. It is recommended
that male and female quick disconnects be used opposite each other on the truck to provide an uninterrupted circuit.
Once the lines have been connected and the circuit continued, the pump could then be turned on to continue
operations.
