Model DL-3 - High Capacity Loader

The DL-3 does more volume! Introducing the model DL-3, nicknamed “the Twister”. Engineered for high volume collection operations after hurricanes, icestorms, or tornadoes. Operated by dual mechanical joystick controls located at the stationary top-mount seat. The DL-3 is great for disaster cleanup, but is also versatile enough that you can use it for your regular bulky trash and brush collection routes.

  • Faster than chipping and less invasive than a wheel loader
  • Single operator turn-key system
  • Great tool for hauling land clearing or site prep debris
  • Duty cycle rated and proven
  • Stationary top-mount mechanical joystick controls
  • 40-45 cubic yard trash dump body
  • ANSI Z245 Compliant

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.

OUTRIGGER STYLE
Out and down outriggers improve safety in traffic and reduce damage to streets.

NO EXPOSED GEARS
Boom swing does not have any exposed pinion or bull gears. Petersen’s rotary actuator boom swing method is lower maintenance.

TELESCOPIC TIP EXTENSION
Four foot tip extension adds flexibility and maneuverability. Tip extension hoses are enclosed and protected.

SINGLE POINT OF RESPONSIBILITY
Petersen Industries manufactures and installs both the grapple loader, including bucket and controls, and the trash dump body.

HEIGHT
The standard dual walk-thru has an overall height of 11’3″.

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.

BUCKET ROTATION
Continuous rotation for convenience.

NO HOSES BELOW BUCKET ROTATOR
Reduced downtime due to elimination of hoses in bucket jaw area.

ANTI-SCALPING
Reverse curve motion of bucket helps prevent scalping of lawns.

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 lbs. 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.

Trash Body

22 feet, 45 cubic yard capacity is standard size. Solid plate floor on cross members with 12″ centers.

Operator Controls

Operator station is located on a stationary platform above the truck cab to provide good visibility of the loading area and of the inside of the dump body. Two mechanical six function joysticks located on either side of the operator seat control loader operation. Outrigger controls are located to the left of the operator seat. Body dump controls are located inside the chassis cab.

Structural

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.

Dual Walk-Thru Controls

dual-walk-through-controlsGreaseless dual controls are operator friendly and maintenance free!

• DUAL CONTROLS: Control platform to be located directly behind conventional cab to allow operator access from the truck cab without ever having to touch the ground.  A single bank of control valves to be mounted at the mid-point of loader, with control handles accessible from the operator platform on either side of truck. Control handle pattern must be the same on both sides of the truck for superior visibility. Control handles shall not require lubrication. A “Grip Strut” serrated steel walk platform is included.

 

QUADSTICK® mechanical controls

quadstick-controls

Completely mechanical! No high maintenance electronics!

• JOYSTICK (dual walk-thru):  Petersen mechanical QUADSTICK® controls.  Each of the four joysticks has six functions to control loader operation.  Outriggers are controlled by two joysticks at the center of the operator platform.  When applicable, body dump is controlled by a single lever at the center of the operator platform.

PATENT #7,353,652 B2

 

Stationary Top mounted controls

top-mount-controls

PI Stationary Top Mount controls give the operator a good view into the body for sorting.

• TOP MOUNT:  Operator station is located on a stationary platform above the truck cab.  The control valves are mounted under the seat, with the control handles between the operator’s legs for easy access.  A ladder, safety railing, padded seat with arm rests, and seat belt are provided.

 

Top mounted joystick controls

topmount-joysticks

Mechanically linked! No high maintenance electronics!

• JOYSTICK (top mount): Two mechanical six function joysticks located on either side of the operator seat control loader operation.  Outrigger controls are located to the left of the operator seat.

 

Outrigger pads

outrigger-pads

4x12x12 rubber pads mounted on bottoms of outrigger feet help prevent outriggers from causing damage to curbs etc.

 

All purpose trash grapple

all-purpose-trash-grapple-th

Petersen’s trash bucket is actuated by a single double-acting cylinder and capable of continuous rotation with no need for physical stops.  The bucket motor, Model RE, has a 5,500 in. lbs. torque rating. Petersen buckets have the capability to be rolled over on the load without damage to any components, allowing for a maximum load while keeping boom height within acceptable limits.  An anti-scalping feature is standard and advantageous for jobs requiring increased precision (ex: sidewalk removal).

The bucket also incorporates:

  • 3/16″ plate, smooth steel clamshell scoop for leaves and sand
  • End plates minimum of 5/8″ thick and of A-572 grade 50, 50,000psi steel
  • A minimum of 5 ribs per side to handle branches, logs and appliances
  • A trample ram in the center for compressing trash in body.
  • Replaceable bolt-on bucket blades made of high impact tempered steel

The bucket is 4 ft. long with an opened width of 5 ft. between pickup blades.  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.  There are no hydraulic hoses located below bucket rotator.

 

Crab – front load container attachment
