Main Body


The TASK® VIPER® 4D is designed with four-directional travel manouevrability, allowing operators to be smarter, more efficient and cause less damage to goods when handling larger loads.

The VIPER® 4D’s revolving load wheels add a lateral axis of direction to the standard forward and reverse movement. This allows operators to travel side-wards down narrower aisles with the same wide loads.

Built as standard with a tilting carriage, side-shift and pantographic reach, as well as the distinctive 4-directional travel system; all the functions including lift and lower are controlled using Task’s VTC (Variable Total Control) module. This provides users with absolute control when operating the VIPER®.



Power & Control.

The VIPER® 4D reach truck eliminates the need for right-angle stacking; reducing the aisle widths required for handling large, heavy loads.

Whether you are handling long steel beams, large tubing, timber lengths or any other large materials, the VIPER® 4D’s unique 4-directional mechanism enables outstanding useability and
control resulting in less product damage.


The Curtis® Programmable Control System with Multi-mode allows infinite control of all machine functions.

Authorized TASK® support technicians are able to adjust and optimize settings to meet environmental requirements or different operator skill levels.

What is a ReachStacker?

More Info

The Walkie Reach Stacker is the ultimate addition to any warehouse. Based on a straddle stacker type design; reach stackers also incorporate a Reach function to allow operators to handle materials with more precision.

The exceptionally versatile TASK Viper Walkie Reach Stacker has a number of attributes that help maximize productivity, and increase efficiency in the warehouse. Firstly our Reach function utilises a pantographic mechanism which has remained unchanged over our 40 years of manufacturing. The heavy duty design of the pantograph reach mechanism combined with “matched” heavy duty tapered roller bearings and a single large reach cylinder are proven to be the strongest, and most reliable combination in the international market.

Our pedestrian Walkie Reach Stackers don’t require an area for the operator to sit down or operate complex controls; eliminating the need for extensive training and licenses.

Our Reach Walkie Stacker is operated with one person standing behind it. Using our ergonomically designed handles and control system, operators can easily maneuver the unit, and use up and down lift, tilt, reach and side-shift controls to handle materials.
