Lightning Loader Grapple Truck Features

  1. CONTROL OPTIONS: Greaseless dual walk-thru controls operational from either side of truck. Petersen also offers QUADSTICK® controls and stationary top mount controls with joysticks or valvehandles.
  3. OUTRIGGER STYLE: Out and down outriggers improve safety in traffic and reduce damage to streets.
  5. NO EXPOSED GEARS: Boom swing does not have any exposed pinion or bull gears. Petersen's rotary actuator boom swing method is lower maintenance.
  7. TELESCOPIC TIP EXTENSION: Four foot tip extension adds flexibility and maneuverability. Tip extension hoses are enclosed and protected.
  9. SINGLE POINT OF RESPONSIBILITY: Petersen Industries manufactures and installs both the grapple loader, including bucket and controls, and the trash dump body.
  11. HEIGHT: The standard dual walk-thru has an overall height of 11'3".
  13. SAFETY LOCKING VALVES: Boom cylinders have counterbalance valves, and outrigger down cylinders have pilot operated check valves to prevent leakdown or collapse in the case of hose rupture.
  15. BUCKET ROTATION: Continuous rotation for convenience.
  17. NO HOSES BELOW BUCKET ROTATOR: Reduced downtime due to elimination of hoses in bucket jaw area.
  19. ANTI-SCALPING: Reverse curve motion of bucket helps prevent scalping of lawns.
  21. WARRANTY: Three year structural, one year hydraulic.

Weight of bucket and/or attachments must be subtracted from lift capacities shown. Standard bucket weighs appx. 1000 Ibs. Capacities shown do not exceed 85% of vehicle tipping moment with outriggers fully extended on firm, level ground.

Bucket Features

All purpose clamshell design, 4 feet wide with an opened width of 5 feet. Replaceable bolt-on bucket blades made of high impact tempered steel. Anti-scalping bucket sides are pivot mounted to provide a horizontal closing action rather than a vertical digging motion. Sides are mechanically linked to single
hydraulic cylinder to ensure both sides close and open together. Continuous rotation. No hoses below bucket rotator.

Chassis & Hoist Requirements

The Petersen HL-3loader system requires a heavy-duty chassis & hook-lift hoist. The complexity of the system and diversity of chassis/hoist combinations available necessitates that Petersen check each one individually prior to sale. The following are minimum requirements:

  18ft, 24 cy
GVW 54,000 (tandem)
Cab to Trunion 174
Hoist Capacity 32,000 lbs
Effective Length 16ft 10in -17 ft 7in

These are not complete chassis specifications. Call your Petersen representative about other possible
chassis arrangements and for complete chassis specs

Trash Body

18 feet, 24 cubic yard capacity is standard size.
3/16 in solid plate floor on cross members with 12 in centers.

Operator Controls

Dual manual controls (greaseless) for outriggers and loader on both sides of truck for easy access and visibility. A "Grip Strut" serrated steel walk platform and steel handrail is included. Frame lock control lever is located at valve bank. Also available with QuadStick controls (mechanical six-function joysticks).


A-frame pedestal design allows flexing under repeated load shocks. Replaceable Cast Nylon Bushings used in head assembly. Head assembly is stress relieved. Reinforced connection points with hardened pins and replaceable bushings. Counterbalance valves used on all boom cylinders and pilot operated check valves used on vertical outrigger cylinders.
