AUTOMATIC COVERING SYSTEM
INSTALLATION INSTRUCTIONS
PRIOR TO INSTALLING THE FLOW DIVERTER AND COVER CONTROL
VALVE INTO YOUR TRUCKS HYDRAULIC SYSTEM. WE RECOMMEND
THAT YOU CHECK WITH HOIST MANUFACTURER FOR POSSIBLE
WARRANTY IMPLICATIONS.
READ AND UNDERSTABD THESE INSTRUCTION COMPLETELY
BEFORE BEGINNING THE INSTALLATION. USE THESE INSTRUCTIONS
WITH THE DRAWINGS INCLUDED. UNPACK, IDENTIFY AND
FAMILIARIZE YOURSELF WITH THE VARIOUS COMPONENTS OF THE
SYSTEM.
1. MOUNTING THE GANTRY AND ROLLER ASSEMBLY
Pick a suitable place on the chassis of the truck directly behind the cab to mount
the Gantry and Roll Assembly. Clear away or re-route any hoses, cables etc. that
may interfere with mounting the Gantry to the chassis. Locate and clamp –2-
Chassis Mounting Angles to the frame. You may turn these angles in over the
chassis or out from the chassis depending on the chassis width of your truck.
Allow a minimum of 3-4” between the front of these mounting angles and the
back of the cab. This will provide clearance for the Roller Assembly as it moves
up and down vertically. The mounting angles must be in the exact same position
on either side of the chassis. A good way to ensure this is to check the squareness
of a crossmember to the chassis rails and if square, use that as a reference point
for locating the mounting angles. The height of the mounting angles should be the
same if placed directly on top of the chassis flanges. If not, the height can be
checked by measuring each side or with a level (assuming the truck is level).
Once the mounting angles have been properly located and clamped, they must be
bolted to the chassis with ½ grade 8 hardware (not supplied). Four bolts are
recommended on each side.
NOTE: DO NOT DRILL INTO THE CHASSIS FLANGE OR ANY CLOSER
TO THE FLANGES THAN THE TRUCK MANUFACTURER DID.

www.pioneercoverall.com 6866-353-5826
Drill the holes thru the mounting angles and chassis, then fasten securely with the
hardware specified above. Follow the manufacturers recommendation for the
proper amount of torque on the bolts.
Mount the complete Roller Assembly (factory pre-assembled) on top of the
Gantry Assembly by aligning the four ½” studs on the bottom of the roll base with
the slots in the pads on the gantry legs.
NOTE: THE WINDSCREEN MUST BE ON THE SAME SIDE OF THE
GANTRY AS THE CROSS BRACE NEAR THE TOP OF THE
GANTRY. THE HYDRAULIC MOTOR MUST BE ON THE DRIVERS
SIDE.
Secure the roll base to the top of the gantry with –4- ½-13 nuts and lockwashers
provided. Assemble the Gantry Cylinder to the Clevis Eye Pads found on the
Gantry and roll base using –2- clevis pins and cotters.
NOTE: THE PORTS ON THE CYLINDER SHOULD FACE TO THE LEFT OR
DRIVERS SIDE WHEN VIEWED FROM THE REAR.
Using an overhead crane, chain fall or forklift, with a sling, lift the entire Gantry and
Roller Assembly up on top of the mounting angles. Center the Gantry on the
mounting angles making sure the center of the gantry is aligned with the center of the
chassis. Check to make sure the gantry is plumb and square to the chassis. Weld all
around the bottom of the gantry legs to the mounting angles adding gussets and or
braces (not provided) where necessary. It is strongly recommended that triangular
gussets be added to the gantry to anchor it firmly to the chassis in a front to rear
position to minimize front to rear movement.
2. INSTALLING THE FLOW DIVERTER AND COVER CONTROL VALVE
Reference: Hydraulic Schematic Drawing
NOTE: FILTRATION OF 30 MICRON OR BETTER MUST BE USED WITH
THESE COMPONENTS.
Select a suitable place for the Cover Control Valve that will allow for ease in
operation while not interfering with the hoist, container or hoist controls. It is
suggested that this valve be mounted on the drivers side of the truck directly behind
the cab. This position will allow for safe and easy operation. In addition, if the hoist
controls are located there, the operator can run both systems from the same location.
Fabricate a mounting plate for the Cover Control Valve that will bolt to the chassis or
weld to an existing bracket. Bolt the valve to the bracket using 5/16 grade 5 hardware
(not provided).
The Flow Diverter, on a conventional hoist may be installed between the pump and
the main control for the hoist, (the Pioneer covering system requires 5 G.P.M. flow
which may adversely affect the hoist function, in this case mount the diverter after the
hoist controls) but on a hook lift, the Flow diverter, must be installed after the hoist

www.pioneercoverall.com 7866-353-5826
controls (downstream, utilizing a power beyond valve). Pick a suitable place to mount
the Flow Diverter. These components may be hard piped or the diverter may be
bolted to a bracket (not supplied).
Hoses and fittings for connecting the diverter to the pump, the diverter to the hoist
controls, the cover control valve to tank, are not supplied because of the many places
these parts can be mounted.
NOTE: USE ONLY PIPE DOPE SUCH AS RECTORSEAL ON PIPE THREADS
DO NOT USE TEFLON TAPE!!!
Follow the hydraulic schematic and make the proper connections from the pump or
valve to the flow diverter, from the diverter to the hoist control (excess flow side)
(if necessary), from the diverter to the Cover Control Valve (priority side), from the
cover control valve back to tank and from the PRV back to tank. Hoses that are used
to make these connections must be equivalent to the original equipment provided by
the hoist manufacturer. If the Diverter are is installed between the pump and the hoist
control, set the Diverters’ PRV, 100 PSI higher than the hoist. If the Diverter is
installed after the hoist control (downstream) then the Diverters’ PRV can be set to
match the pressure required by the hydraulic motor.
3. ACTIVATING THE GANTRY LIFT CYLINDER
Follow the hydraulic schematic and install the proper fittings into the gantry lift
cylinder. Attach –1- 9’ hose to the rod end fitting on the cylinder and attach –1- 6’
hose to the base end fitting on the cylinder.
The valve section labeled “UP – DOWN” is used to control the vertical motion of the
gantry. Install –2- elbows onto the top of this section. Lead the hoses from the gantry
cylinder toward the cover control valve using wire ties etc. to secure the hoses along
the way. Connect the hoses to the elbows on top of the valve. At this point it doesn’t
matter which hose goes to which side of the valve. They can be swapped later on.
To bleed the lines, start the truck and engage the PTO. Operate the “UP-DOWN”
valve in both directions to fill the cylinder with oil. Operate the valve so the cylinder
moves upward. Move the cylinder to the end of its stroke crack open the fitting at the
rod end of the cylinder to let any air escape that may be trapped in the cylinder. Re-
tighten the fitting and move the cylinder downward to its collapsed position. Crack
open the fitting at the base end of the cylinder to let any air escape that may be
trapped in the bottom of the cylinder. Re-tighten the fitting and run the gantry up and
down a few times to force any air in the cylinder or lines back to tank. If the hoses are
reversed, that is, if the gantry goes up when the handle is moved to the down position,
exchange the hoses. Re-bleed if necessary.
Apply a dry film lubricant (Dry Moly) to the telescopic gantry legs to cut down on
friction when moving up and down.
The relief valve on the left front of the cover control valve has been factory pre-set. If
the gantry does not move smoothly or if the hydraulic motor does not wind the cover
onto the roller smoothly when the cover control valve has been engaged, the the relief
valve may need to be adjusted. This is done as follows:

www.pioneercoverall.com 8866-353-5826
Remove the acorn cap that covers the adjusting screw.
Loosen the Jam Nut.
Turn the screw ¼ turn clockwise and try the system.
Repeat until the motor winds the cover smoothly and fluid is not dumping
over relief.
Tighten the Jam Nut and replace the acorn nut.
NOTE: THE RELIEF VALVE SHOULD ONLY BE TURNED IN ENOUGH TO
MAKE THE MOTOR ROLL THE COVER UP SMOOTHLY. FURTHER
ADJUSTING OF THE RELIEF VALVE WILL NOT MAKE THE MOTOR GO
ANY FASTER. IF THE RELIEF VALVE IS TURNED IN TOO FAR, DAMAGE
TO THE UNIT OR PERSONAL INJURY COULD RESULT.
4. ACTIVATING THE HYDRAULIC MOTOR
The valve labeled “COVER – UNCOVER: is used to control the Hydraulic Motor
which winds and unwinds the cover from the roller. Follow the hydraulic schematic
and install the proper fittings into the Cover Control Valve and the Hydraulic Motor.
The hoses that connect to the motor and valve are already connected to the Gantry.
The lower ends go to the Cover Control Valve and the upper ends connect to the
motor. Make the proper connections and affix the hoses to stationary objects. Make
sure the hoses that connect to the hydraulic motor have a nice loop in them and there
are no kinks in the hoses. It is advisable to run the Gantry up and down to make sure
the hoses track properly from the collapsed position of the gantry to the extended
position of the gantry. The hoses should have enough slack in them to allow the
gantry to extend and retract completely without kinking the hoses. If adjustments
need to be made to the hoses, they can be slid thru the clamps securing them to the
gantry. It is important that the hoses have enough slack in them to allow for full
vertical movement of the gantry, but no so much slack that they flop around when the
gantry is collapsed.
Operate the “COVER – UNCOVER” section of the control valve to make sure the
roller is turning in the proper direction. With the valve in the UNCOVER position,
the roller should turn in a counterclockwise direction as viewed from the driver side.
The tarp is always wound onto the roller in a clockwise direction as viewed from the
drivers side. Swap the hoses if necessary to make the roller turn in the proper
direction. Make any corrections or adjustments necessary. Make sure the hoses are
secured to immoveable objects and no chafe points are evident.
5. DETERMINING THE PIVOT POINT AND MOUNTING THE ARMS
NOTE: THE ARMS AND BRACKETS MUST BE MOUNTED TO A
FABRICATED STRUCTURE THAT IS BOLTED TO THE CHASSIS. THIS
STRUCTURE MUST EXTEND OUTWARD FROM THE CHASSIS SO AS TO
ALLOW FOR THE WIDEST WIDTH CONTAINER THAT WILL BE CARRIED
ON THE TRUCK, WHETHER OR NOT THE CONTAINER IS TO BE COVERED.
(ex: self contained compactor containers) THIS OUTSIDE WIDTH FROM ARM

www.pioneercoverall.com 9866-353-5826
MOUNTING BRACKET TO ARM MOUNTING BRACKET CANNOT BE MORE
THAN 108” TO BE IN COMPLIANCE FEDERAL DOT REGULATIONS. CHECK
WITH YOUR STATE OR LOCAL DOT TO FIND OUT IF THIS STANDARD
APPLIES IN YOUR AREA. IF IT DOES NOT APPLY, THEN YOU MUST
MOUNT THE UNIT IN COMPLIANCE WITH YOUR LOCAL DOT
REGULATIONS.
NOTE: IF THE FENDERS ON THE TRUCK ARE WELL CONSTRUCTED,
THAT IS, HEAVILY GUSSETED AND BRACED, IT MAY BE POSSIBLE TO
UTILIZE THE FENDERS AS PART OF THE SUPPORT STRUCTURE FOR THE
ARM MOUNTING BRACKETS.
A. Put the longest and highest container that is to be covered on the truck. This
container is used to determine the pivot point for the arms and to determine the
arm length. If your containers are not the same length, you may have to modify
this guideline to comply with the majority of containers you have.
B. Measure the distance from the back side of the roller to the front side of the rear
door on the container. Dividing this measurement in half will give you a starting
point for locating the Arm Mounting Brackets (G 1531).
If the center line measurement obtained above falls over a fender, it is possible to
utilize the fender in determining the exact pivot point. If the centerline
measurement does not fall near a fender then you will have to construct some type
of TEMPORARY support for the Arm Mounting Bracket, while the exact pivot
point is found. Temporary support can take the form of tack welding the Arm
Mounting Bracket (G 1531) to the container itself or tack welding a plate to the
container, to lower the bracket down to its proper position and the tacking the
bracket to the plate.
In either case, proceed as follows: Tack weld -1- Arm Mounting Bracket to the
fender or to the temporary support, so that the front of the bracket (the front has
the bend on it) lines up with the measurement determined above.
Mount the Arm Mounting Bracket as low as possible without interfering with the
tires or the hoist cylinder(s). It is advisable to have the greatest included angle that
you can derive between the arm and an imaginary horizontal line thru the center
of the Arm Mounting Bracket in a front to rear plane.
C. Insert -1- Bow Corner (G 2099) into an Arm and place the Arm onto the Arm
Mounting Bracket. Swing the Arm towards the gantry and adjust the bow in or
out so that it is approximately 2” to the rear of the bearing plate. Secure the bow
to the arm with clamps, and swing the arm thru its arc to the rear of the truck. The
bow, which will hold the rear section, should line up with the front edge of the
door on the container. If the bow goes past the rear of the container, the Arm
Mounting Bracket will have to be moved forward. If the bow falls short of the
rear of the container, move the Arm Mounting Bracket toward the rear of the
truck. Re-position the bracket if necessary and re-check as outlined above.

www.pioneercoverall.com 10 866-353-5826
Once you are satisfied that the position of the Arm Mounting Bracket is correct,
carefully mark the exact location of the bracket on either the fender of the
temporary support. You are now ready to construct a support structure for the
Arm Mounting Bracket.
Some points to remember are:
-DO NOT WELD TO THE TRUCK CHASSIS, DRILL AND BOLT ONLY.
Follow the chassis manufacturers recommendations.
-Utilize existing bolts if you can.
Make sure that the structure is well supported and gusseted. There is apt to be
considerable vibration at this point along the chassis which can lead to failed
welds.
The structure must be:
-Plumb (vertical) and level (horizontal).
-Low enough so that it will not interfere with any container or its accessories.
-High enough to allow access to the tires and wheels.
-Wide enough apart so ANY container you may be hauling will clear the arms of
the covering system, even if the container is not to be covered. KEEP IN MIND
LOCAL AND STATE WIDTH REGULATIONS AS WELL AS FEDERAL
DOT.
-Must be the same distance out from the chassis on both sides.
D. Install both arms, with the bows clamped in place, onto the Arm Mounting
Brackets using -2- Retaining Rings (G 1532) (one on each side) and -6- Roll Pins
(G 1513) (three on each side). Place the Arm onto the Arm Mounting Bracket so
that the short leg of the spring is on the inside of the Arm Mounting Bracket
facing the front of the truck. Tap -1- retaining ring over the round part of the Arm
Mounting Bracket. Insert -1- roll pin into each of the three holes in the bracket
and tap down until they are flush with the outside of the retaining ring.
E. With both Arms sitting on the top rear of the container, measure the distance
between the arms just above the Arm Mounting Brackets. You will have to raise
the hoist to make this measurement so be careful that the arms don’t slide off the
container and fall to the ground, which may cause physical injury or damage to
the unit. Lower the hoist and measure the distance between the top of the arms
(where the bows go into the arms) and adjust the arms in or out so that the
distance between the arms at the top is the same as the bottom.
Measure the distance between the ends of the bows. Taking this measurement and
adding 12” to it will give you the proper length of the Rear Section (H 7037). Cut
the rear section to length, if necessary, and install onto the bows, allowing it to
overlap the bows by 6” on both sides. Attach the bows to the arms by drilling a
¼” hole thru the arm and bow approximately 8” down from the top of the arm.
This measurement may vary depending on how much bow is left inside the arm
(the long leg of the bow is 24” long). Insert -1- cotter pin (provided) thru the hole
and open fully.

www.pioneercoverall.com 11 866-353-5826
You are now ready to attach the rear section to the bows and attach the cover to
the unit.
6. INSTALLING THE COVER
A. Remove the Rear Section (H 7037) from -1- Bow to allow the cover to be slid
over. Unfold the cover and find the rear boot (pocket). Slide the cover onto the
Rear Section making sure that the bows go inside the Rear Section as previously
described. Fasten the Rear Section to the Bows by drilling a ¼” hole thru the Rear
Section and Bow approximately 3” in from the end of the Rear Section on each
side. Insert -1- ¼” Cotter Pin (provided) thru each hole and open fully. Attach one
end of -1- Cover Spring (G 2014) to the eye portion of the cotter pin and attach
the other end of the cover spring to the grommet on the rear corner of the cover on
each side.
B. Attach the cover to the roll using -5- sheet metal screws and fender washers
(provided) as follows:
Wrap the cover ¾ of the way around the roller in a clockwise manner as viewed
from the drivers side. Center the cover on the roller and the attach the cover to the
roller, starting in the middle and working out to the left and right. Make sure that
the cover is straight on the roller and that the fender washers are firmly in place
over the grommets.
7. TYING THE COVER SHOCK CORDS (EXPANDABLE TARP ONLY.)
The shock cords on the top of the cover are designed to fold the cover upward and
inward so that the 9’ wide cover will roll up between the bearing plates on the roll
assembly. This is accomplished by firmly tying one end of the shock cord to the a
loop on one side of the cover and then passing the other end of the shock cord thru the
loop in the center of the cover towards the other side and stretching the shock cord so
that pulls the cover up and in. It is only necessary to put enough tension on the shock
cords so that the sides of the cover do not rub on the bearing plates when the cover is
being wound onto the roller. Pass the shock cord thru the loop on the other side of the
cover and tie a knot securely when adequate tension has been achieved. The best test
for the proper amount of tension, is to check the cover while it is being wound on the
roller. The cover should not “bunch up” and/or rub on the bearing plates nor should it
pull in too far away from the edges of the container. Shock cords that are tight are as
bad as those that are too loose. Be patient, they may have to be adjusted a couple
times in order to get them right. Make sure that the first couple of winds that go onto
the roller are smooth and square. If not, the cover will wind up faster on one side than
the other, causing the arms to go out of synchronization because of the extra material,
which makes a larger circumference to that side of the roller.

8. OPERATING THE UNIT
The controls used to operate this unit are a VALVE Labeled COVER-UNCOVER
which controls the arms and cover, and a VALVE labeled UP-DOWN which controls
the vertical motion of the Gantry.
TO COVER THE CONTAINER:
1. Make sure the truck is clear of overhead wires.
2. Make sure that there is nobody in the container or in the path of the arms.
3. Move the arms upward from the roll approximately 2-3 feet by using the Cover-
Uncover Valve.
4. Raise the Gantry to its maximum height using the Up-Down Valve.
5. Load the container onto the truck.
6. Move the arms to the rear of the container to cover the load. Release the valve
when the rear section is firmly seated on the rear of the container.
7. Lower the Gantry so that the top of the windscreen is even with the top of the
container. This stretches the cover taut, preventing wind from getting under the
cover and the bellowing and whipping that may occur.
TO UNCOVER THE CONTAINER
1. Make sure that the truck is clear of overhead wires.
2. Make sure that nobody is in the container or in the path of the arms.
3. Raise the Gantry up to its maximum height.
4. Using the Uncover valve, move the arms to the front of the truck stopping 4-6 feet
from the roll.
5. Unload the container from the truck.
6. Lower the Gantry to its rest/travel position.
7. Wind the cover onto the roller and release the valve when the Arms and Bows
contact the Bearing Plates.
MAINTENANCE TIPS
1. Keep the torsion spring at the base of the arms free from debris.
2. Periodically apply a spray lubricant such as WD-40 to the bearings.
3. Replace any worn or broken parts immediately.
4. Check all fittings and connections weekly. Correct as required.
5. Grease telescopic Gantry legs weekly.

www.pioneercoverall.com 13 866-353-5826
TIPS FOR THE OPERATOR
1. Make sure the truck is clear of overhead obstructions before operating the unit.
2. Do not operate under any overhead wires.
3. Keep Hands clear of any moving parts.
4. Make sure nobody is inside the container, or in the path of the arms before
operating the unit.
5. Pay attention to safety decals.
6. Release the valve as soon as the Rear Section contacts the rear of the container, or
when the Arms are seated on the Bearing plates.
7. Release the valve when the Gantry has been fully extended or retracted.
