Power-to-weight ratio. Ask a tradesperson barneshydraulicpumpmailorder for an opinion about a power tool and you''re likely to hear how powerful it is for its weight. Most of us want as much power as we can get for the weight we carry. It''s easy to feel the difference between the most powerful and the least powerful drills, barneshydraulicpumpmailorder but it''s harder to judge power in relation to weight. I calculated power-to-weight ratios by dividing each tool''s torque rating by its weight. That allowed me to compare drills on the basis of inch-pounds of torque per pound of weight. I used the manufacturer''s torque specs but weighed the tools myself.

There is no more versatile machine in the mobile equipment marketplace than the skid-steer loader. And with typical yearly sales in excess of 60,000 units, it''s clear that these barneshydraulicpumpmailorder machines, seen by many as the Swiss Army knife of construction machines, have penetrated a wide range of applications.But not all of them, in part because of the very nature of the beast.A skid-steer loader, as the name indicates, maneuvers by "skidding"--slowing or stopping the wheels on one side of the machine, while keeping the other barneshydraulicpumpmailorder side rolling. This system, highly valued because of its simplicity and effectiveness, particularly in tight spaces, does have drawbacks in some applications. When operated in grassy areas, skidding the tires can scuff up the turf, a real nono in venues such as parks barneshydraulicpumpmailorder or golf courses. Even where ground disturbance is not an issue, tire wear, or even wearing of the surface on which the machine operates, can sometimes cause problems.
