OPERATION

8000 SERIES OWNER’S MANUAL

The 8000 crane is designed to provide excellent service if operated within the maximum allowable load

specifications stated on the unit’s “Angle Indicator Plate” located on either side of the boom. load charts are also

included on pages 6 and 7. The load information charts should be studied before operating the crane. Exceeding

the stated load limit can cause tipping or structural failure. You should familiarize yourself with proper operation

procedures to avoid overloading the crane. As an example: If a load of 5000 pounds were lifted at an 11’ boom

length at 30°, lowering the boom would cause an overload situation.

The 8000 crane is relatively simple to operate. Prior to field use, you should familiarize yourself with the controls

and how the unit reacts to the controls. Practice operations should be performed with a light test weight

progressing to a heavier test weight.

• Connect the winch cable eye to the pin on the bottom of the manually extendible boom section.

• Insert cable through the snatch block by removing the cotter pin and disassembling.

• eassemble the snatch block. Be sure to reinsert the cotter pin in the snatch block.

You should also use a “two-part” line for loads under 4000 pounds if you want to slow down the line speed of

the cable.

It must be understood that all load ratings are formulated on 85% of tipping. Tipping is defined as a tire breaking

contact with the ground. Furthermore, all load ratings are dependent upon compliance with the following:

• The unit has been correctly installed in accordance with chassis requirements and truck body manufacturer’s

specifications.

• The intended operation is carried out on a level, solid surface with proper outrigger placement.

TASK PE FO MANCE

1. Position the 8000 crane as close to the job as possible on a firm, dry, and level surface. Avoid overhead

obstruction on the work side of the unit.

2. Set the parking brake.

3. Extend and lower the outriggers until firm ground contact is made. On soft ground, use bearing pads to

prevent sinking or tipping.

4. un the winch line out before extending the boom.

5. Make sure the connection to the load is secure and will not come loose when lifting the load.

The 8000 crane is equipped with a counterbalance valve inside the lift cylinder to protect against overloading. In

an overload condition, the boom will not elevate. Attempts to winch the load will cause a downward feathering of

the boom until the overload condition is reduced. The counterbalance valve will also keep the boom from coming

down in the unlikely event of a rupture to the hydraulic hoses that supply oil to the lift cylinder.

A pressure sensitive switch is also located in the lifting cylinder that can detect an overload situation. This causes

a shutdown of the winch up, boom extension out, and boom lower functions, and automatically resets after the

crane has been moved out of overload position.

An anti-two block feature is also provided on L X models

OTATION STOP

OTATION STOPOTATION STOP

OTATION STOP

A stop to prevent the unit from rotating continuously is located on the crane base. The stop is installed so that a

full 360° plus is obtained. A stop lever is attached to the turret and extends so that it will contact the rotation stop

on the base assembly. Do not remove the stop assembly. Continuous rotation will result in damage to the wiring

harness and/or hydraulic hoses.

ELIEF VALVES

ELIEF VALVESELIEF VALVES

ELIEF VALVES

The 8000 crane requires a relief valve located at the reservoir to maintain crane operating pressure at 2850 PSI.

This relief valve is not supplied unless using a s hydraulic reservoir. It is the customer’s responsibility to

provide this relief valve when using a reservoir not supplied by s. The main function of this relief valve is

to prevent overloading of the system if the boom is inadvertently rotated against an immovable object, while one

of the other hydraulic functions is also being used. The relief valves would not normally require adjustment, but if

the correct relief valve setting is suspect, refer to the maintenance section of this manual for the proper

adjustment and testing procedure.

HYD AULIC FLUID SPECIFICATION

HYD AULIC FLUID SPECIFICATIONHYD AULIC FLUID SPECIFICATION

HYD AULIC FLUID SPECIFICATION

Minimum viscosity specifications for hydraulic oil to be used in the crane should be Chevron AW68 or equivalent

to eliminate the necessity of seasonal oil changes under normal temperature conditions. For operations in below

freezing temperature, use a hydraulic fluid having a viscosity of 3000 SSU’s.

Operating temperature of the hydraulic fluid should be within the range of 120°F—160°F (49°C—82°C).

NOTE

NOTENOTE

NOTE: Arctic conditions present special requirements and considerations. Consult your oil supplier for the proper

fluid for working under these severe conditions.

In addition to meeting the viscosity requirements, hydraulic fluid used in the system should contain the following

additives:

• Anti-foam inhibitors

• Antioxidant inhibitors

• Anti-wear additives

• ust resistant additives

Air that is trapped in the cylinder will cause an erratic “bumpy” condition. To expel the air, hold the affected

control open after the function has “bottomed out”. Move the function in the opposite direction and again hold

the control open. Attempt to operate the crane in a normal manner to determine if the air has been purged.

When purging is complete, reevaluate hydraulic fluid level and add fluid if necessary.

Contamination of the hydraulic oil by solvents, water, dust or other abrasives will result in premature breakdown

of the oil’s anti-foam, lubrication, anti-rust and viscosity properties. Periodically, a sample of the hydraulic oil in

the system should be drawn off and its condition checked for breakdown. To check quality:

1. Place oil sample in a clean glass.

2. Smell oil to detect a burnt or rancid odor.

3. Examine the oil for a cloudy or dark color.

4. Allow the sample to stand for several minutes and inspect it for water, which will settle to the bottom.

When any of the results above are observed, the system should be purged to the bottom and filled with new oil.

procedure for purging the system is as follows:

1. Locate the unit in an area that provides solid, level footing and space to accommodate the full operating

range of the crane.

2. Stabilize the unit with the outriggers. Move the crane to either side of the truck and extend the lift

cylinder.

3. Drain the hydraulic fluid from the reservoir and clean the suction line filter.

4. emove the reservoir return line. efill the reservoir with Chevron AW68 or equivalent. Direct the return

line into a sump waste container.

5. otate the crane 90 degrees, retract the extension boom, lower the main boom and operate the winch

up and down for approximately ten seconds.

6. All components are now purged. eplace the return line filter cartridge and reinstall the return line to the

reservoir.

Check the reservoir fluid level and add fluid to within one half inch (1/2”) of the top. The boom elevation

and extension cylinders must be fully retracted when refilling the reservoir.
