Shortstop 2

Self contained powered by a 20 HP gasoline engine, optional diesel. 50 state EPA & CARB approved. 80 Gallon water tank with 12VDC pump for slump maintenance and cleanup. Shortstop mixers have a turning radius of 21’ compared to 42’ with a large mixer.

Shortstop 2 comes standard with 7’ of main discharge chute and up to 12’ with optional clip on chutes. Unlike large ready mix trucks, the Shortstop 2 maneuvers in tight residential settings for quick placement of concrete without damage to driveways, landscaping and utility lines.

Simple to operate electronic controls are located on the rear of the mixer and in the chassis cab. Heavy-duty 22:1 planetary drive directly coupled to a hydraulic motor powers the drum. The drive features a gimbal mount specifically designed for small concrete ready mix drums. Industrial quality closed center hydraulics insures precise control of the drum.

Installs on a 19,000 lb GVW or larger chassis. We offer turnkey solutions installed on either a new or used chassis. Unit can ship less chassis for customer or up-fitter installation. Quality components backed by over forty years experience insures many years of reliable service.

Optional charging chute extension can be quickly installed for loading from a standard batch plant and removed on the jobsite for clearance under doors and utility lines. The SS2 is also available with a hinged discharge funnel for loading from a cart style batch plant. Low clearance height and low curb weight are two of many reasons contractors and homeowners request the Shortstop.

Shortstop 2 is designed specifically for delivery and placement of small loads. Shortstop Mixers do not require a CDL license. Earn great profits servicing the small load concrete market. Municipalities and contractors and homeowners all benefit from the cost savings of the Shortstop 2. Contact Ernest Industries to learn more about Shortstop Concrete Equipment.
