Controls Refine Great Skid-Steer Power

摘要

Even with a broad range of weights and horsepowers represented within a fairly narrow segment of skid-steers available today, most equipment manufacturers are relying on the same features — operator stations, hydraulic performance, and attachment versatility to differentiate their midsized machines. The 32 models of mid-sized skid-steers — spanning just 600 pounds of rated operating capacity between 1,600 and 2,200 pounds — include machines with net engine horsepowers ranging from 44 to 82, and operating weights from 5,500 pounds to 7,700 pounds. With standard hydraulic-pump flows ranging from 15.5 to 23 gallons per minute and pressures from 2,400 to 3,450 psi, hydraulic horsepower stretches from 23 to nearly 43. Bucket breakout forces for mid-sized skid-steers run the gamut from 2,900 pounds to more than 7,500 pounds, and arm lifting forces from 2,800 to more than 6,800 pounds.
