Aerial work platform has all-hydraulic control

Forget about expensive fiber optics and temperamental digital controls. Elliott Equipment Co., Omaha, recently developed a full-hydraulic upper platform control package for its HiReach aerial work platform product line. Hydraulic valves and actuators are typically used for moving and positioning aerial booms and platforms, but electronic controls usually command solenoid-operated electrohydraulic valves.

Designed for severe-duty applications, the full-hydraulic upper platform control package is designed to be “spark and electronics free” for special applications such as underground mining (especially the highly corrosive environments of salt mines) and for users that require it as part of their standard work practice. The all hydraulic controls are also completely unaffected by electromagnetic and radio frequency interference.

The full-hydraulic control system was developed with Elliott distributor Mirk Inc, Bartow, Fla., and Aggregate Resource Industries Inc., Springfield, Ore. Aggregate Resource, a drilling and blasting company, purchased an H50F HiReach with a 55 ft working height and an ammonium nitrate fuel oil (ANFO) hose in an oversized cable carrier on the boom. This allows workers to deliver ANFO explosives from within the work platform. ANFO is a highly corrosive and explosive chemical mix used in mining to fracture rock surfaces.

Unlike conventional electronic controls, the full-hydraulic console eliminates many components that would otherwise be damaged from contact with ANFO. Therefore, high costs associated with downtime and repairs are prevented.

The new full-hydraulic upper platform control system should be attractive to those in mining, oil and gas, and utilities worldwide that need equipment that can lift personnel and survive harsh conditions.

The controls are fully proportional, intuitive, and accessible for easy service and maintenance. Elliott Equipment Co. is uniquely suited to serve the needs of end-users that require features not available elsewhere in the aerial work platform and crane manufacturing industry.

Along with full hydraulic controls, Elliott also offers a removable platform roof, transparent control covers, tool lines to the platform including air, welding, ANFO, and pressure washers, and material handling capabilities, among other options.

To build a customized machine, companies can contact the Elliott distributor in their state or country and request a consultation with Elliott’s engineering and sales team.
