Models 420D and 430D backhoe loaders, and 420D IT and 430D IT integrated toolcarrier (IT) configurations, hydraulicfootpump offer new single-lever, pilot-operated, excavator-style joystick controls for smooth, hydraulic loader functions. New models feature Cat 3054T turbocharged, direct-injection. 4-cylinder engines with 4.0 liters displacement, fuel-injection, and Power-Shuttle transmission with on-the-go shitting and synchromesh in 4 forward and 4 reverse gears. Auto-shift option with manual override automatically shifts between second gear and highest hydraulicfootpump selected gear in 5 forward and 3 reverse speeds. Also have standard hydraulicfootpump 2-wheel or on-the-go, all-wheel drive with oil-immersed hydraulic, multiple disc brakes. 420D has 85 net hp. and backhoe digging depth of 14 ft. 5 in. with standard stick; extendible stick pushes depth to 18 It. 1 in. 430D has 94 net hp. and digging depth of 15 ft. 3 in., extendible to 19 ft. l I in. Variable-flow, closed-center, load-sensing hydraulic system adjusts flow and pressure to 3,300 p.s.i. for full hydraulic force to work tools at any engine speed. Single-pin backhoe bucket has 205[degrees] linkage rotation with integrated lifting eye. Operator station includes white-faced gauges, hand throttle, new boom lock position, and pilot-operated stabilizer controls. A portable backhoe that can be towed to a job site, unhooked, and then used has been introduced. Heavy enough for commercial use, the backhoe is ideal for use by farmers, plumbing contractors, homebuilders, landscape contractors, and large-scale gardeners. Circle hydraulicfootpump 108 on inquiry card This duct liner offers a high level acoustic and thermal resistance. It meets thermal performance requirements of many of the most stringent local and state energy codes, including Title 24 of the California Building Standards Code. An encapsulant edge coating covers fibers and prevents flaring of the insulation at the edges (an important IAQ concern with internal duct linings). The airstream surface is treated with an anti-microbial agent to prevent the growth of fungi and bacteria. Knauf. Circle 109 on inquiry card The Wind Guard air curtain is a fixed-speed, belt-driven unit that produces large volumes of air at low operating sound pressure levels. Primary applications are over doors 14-ft. to 26-ft. in height. It can successfully repel gusts of wind up to 30 mph. Heated and unheated models are available, with heated models available in gas, electric, steam and hot water coil designs. Mars Air Doors. The operation of an EAF is a batch process in which steel scrap, pig iron, a source of iron oxide such as roll scale or iron ore, and limestone or burnt lime are charged into the furnace. The roof is closed over the furnace and electrodes are lowered until arcs are established between them and the metallic charge. The heat generated by the arc and the heat developed from the resistance to the flow of current hydraulicfootpump in the metal melts the charge. When the heat (meaning the metal in the furnace) is finished, the furnace is tilted and poured into a tap ladle through a tap hole or spout in the furnace side wall. After each heat, repairs to the bottom and slag line are made by shoveling in a refractory bottom patching material.
