Proven in decades of operation and countless applications across all industries, Ampliroll Hydraulic Hooklift Systems have earned an unsurpassed reputation for quality, reliability and value.

Here are the key facts and advantages that make a hooklift an Ampliroll:


High-Pressure Hydraulic System

For reasons of greater performance, Ampliroll systems employ 5,000 psi pumps. So do fully 75% of hook loader makers in America and around the world. This engineering is rapidly taking the place of less-efficient, low-pressure (i.e., 3,000-3,500 psi) alternatives.

Heavy-Duty Subframe

Constructed of heavy-gauge, bended plate steel with reinforcing cross members, the subframe mounts securely to the truck chassis. It provides a strong and steady foundation from which the hooklift operates.

Tilting Frame with Actuating Arm

The tilting frame is hinged to the subframe with a steel shaft carrying the rear centering rollers. A main, actuating arm is hinged on the tilting frame. It features a mechanical locking mechanism that allows the dumping mode.

Dual Hydraulic Cylinders

Twin dump/lift cylinders provide excellent stability when dumping and loading.

Telescopic Jib

Sliding in the central arm, the telescopic jib supports a wide-open lifting hook which, in turn, enables loading from many positions.

Twin-Pivot Engineering

This design allows for the dumping of uniform piles of materials.

Sliding-Jib Design

The sliding-jib design accepts a greater range of truck body or container lengths. It also enables optimal weight distribution.

Jib-Safety Engineering

A safety valve prevents jib operations during the dump mode. An automatic locking device also actuates whenever the body is raised and is in the dump mode.

Slide-Through Container Locks

These locks safely secure the container or truck body to the hydraulic hoist.        

Counter-Balance Valves

Integral to each hydraulic cylinder, these safety features hold the cylinders securely in place in the unlikely event of a hose break and loss of hydraulic pressure.

In-Cab Controls

Low-pressure hydraulic or air-operated in-cab controls speed loading and unloading. They also enhance operator safety. Drivers do not need to leave the truck, walk on slippery surfaces or stand outside next to moving machinery (as with a cable loader).

Special Steel Alloy Construction

The jib, central arm and tilting frame are constructed of ASTM A572 special steel alloy for greater strength.

Laser Cutting & Robotic Welding

These and other precision construction processes eliminate the need for shims and wear pads.


For selection, savings and service, make Ampliroll your first choice in hydraulic hooklift systems.

Ampliroll Hooklift Systems are manufactured by Marrel – the inventor of the dual-pivot hook loader in 1969 and first again in bringing them to users across the U.S. in 1980. Today, Ampliroll is the only supplier in the U.S.A. of premier hook loader systems and associated equipment.

Unlike many others, we also offer a complete selection of truck-mounted accessories and roll-on/off bodies that we can supply as a package with our hook loaders, allowing for single-source acquisition! Select from aerial lifts, cranes, grapple systems and more. Also choose from cement mixers, dump bodies, flatbeds, septic pumpers, waste containers, water tankers and other interchangeable bodies. In addition, you can select from our line of high-quality pre-owned hooklift vehicles.
