TR3 Route Assistant® Grapple Loader

TR3 Route Assist Grapple Loader

Route Assistant® - Jack-Of-All-Trades

Petersen Industries, Inc., now offers the Route Assistant™ as an option for their legendary TL3 loader. It incorporates a side-loading trough to the front of the dump body and can be a full-trough system or half-trough and cart tipper. The Route Assistant™ option truly makes the TL3 the Jack-of-all-trades loader. The trough can be used to quickly pick up small piles of debris by hand and the cart tipper can be used for missed cans on the route. It is available on a standard or stand-up-right-hand-drive chassis.

Petersen Route Assistant Grapple Loader Advantages


Route Assistant is designed to save time in multiple areas:

  • The work-site set-up is easier and quicker with custom outrigger placement and a boom that can continuously rotate 360° degrees.
  • During operation, the variable speed pump allows you to use any combination of functions without slowing down while dumping. The dump hoist is power up and gravity down with twin multi-stage telescopic cylinders, giving us a 45% faster dump cycle.


In this industry, it’s not only about how many hits you can take, but about how long you can keep operating at peak performance. That’s why Route Assistant offers:

  • The cart tipper can be used for missed cans on the route.
  • A state-of-the-art hydraulic and filtration system designed to keep this vital portion of the loader running as smoothly as possible.
Grapple Loader Hydraulic System


Greaseless proportional dual walk-thru standard lever controls are operational from either side of the truck. Petersen also offers QUADSTICK® controls and stationary top mount controls with joysticks or valvehandles.

TL3 Trash Truck Grapple Loader


Horizontal and vertical outriggers act independently of each other. Allows the operator to custom place around obstructions and traffic patterns.

TL3 Trash Truck Grapple Loader


Notifies the operator when the boom is over legal travel height with an audible buzzer and red light. The boom-up alarm has been a standard safety feature on our equipment for over a decade.

Slack hoses can snag on debris and obstructions. That’s why Petersen designed their “enclosed hose recoil system” and a bucket with no hoses below the rotator.

Grapple Loader big bite bucket


A large cylinder and manifold block keep hoses out of work areas, allowing for a stronger bite force, and ensuring that both sides always work together.

TL3 Trash Truck Grapple Loader grapple


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, 50,000 psi 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.
