Gradall Industries Inc. is introducing the Vacall All Excavate hydro excavator. All Excavate models have dedicated systems that are designed for excavating around water, sewer, gas and utility lines and other jobs that don’t require vast excavation.
The All Excavate has a high-pressure water system that contains a hydraulically driven variable speed system with rheostat control, conserving water usage and minimizing refill time. The system powers a wand that delivers a high-pressure stream to break up material. Water pumps are available in 10, 15 and 20 gpm (37.9, 56.8 and 75.7 Lpm) with 3,000 to 3,500 psi. To protect from freezing, the water system, wand, control panel, tools and worker apparel are enclosed in a heated compartment.
Water tanks are fabricated with aircraft-quality aluminum for extra strength and a lifetime warranty. They are mounted high on the chassis, reducing damage from debris and eliminating any relocation needed to dump the debris tank.
An oval-shaped debris body with cylindrical sides is designed for extra strength and material dumping. An optional flush system cleans the interior of the body, requiring no operator spraying assistance. Powder-coat paint provides a durable finish, while the optional galvanized tank provides a lifetime warranty.
A new AllSmartFlow CAN bus intelligent control system has a programmable LCD display that monitors engine, water-flow and vacuum performance while allowing for more precise boom and reel movements.
