DL3 High Capacity Grapple Loader


Engineered For High Volume Collection Operations!

The DL3 high capacity grapple loader does more volume! Introducing the model DL3, nicknamed “the Twister”. Engineered for high volume collection operations after hurricanes, ice storms, or tornadoes. Operated by dual mechanical joystick controls located at the stationary top-mount seat. The DL3 is great for disaster cleanup, but is also versatile enough that you can use it for your regular bulky trash and brush collection routes and need a larger body size.

Grapple Loader Top Seat

Top Seat

Because of the proportional joysticks, the foot pedal swing, and an oversized seat designed for maximum comfort, you could stay up here all day long.

Grapple Loader Hydraulic System

Hydraulic System

Experience the most precise and efficient execution in the industry. Our variable speed pump gives you control where you want it, when you want it, without slowing down.

Grapple Loader Gear Box

Slewing System/Gearbox

Steady as she goes.
Our stabilizing swing circuit ensures smooth starts and stops, reducing the overall stress on the boom and slewing system. After three seconds of inactivity, the integral break locks down the boom which eliminates the need for a mechanical swing lock.

Grapple Loader Outriggers

H-Style Outriggers

Horizontal and vertical outriggers act independently of each other, allowing the operator to have incredible accuracy in maneuvering around obstructions and traffic patterns. Not only does this provide a wider base than an A-frame system, the vertical outrigger leg is the ideal position for our heavy duty strobe light.

Grapple Loader big bite bucket

Big Bite Bucket

We’ve skinned this larger bucket in Hardox 450 so you can use the full force of the cylinders without worrying about tearing a hole in your bucket. With simple hose routing and brake washers on both axes, this is the easiest and smoothest operating two cylinder bucket you’ll find.
