Load Calculator — Stren-Flex

The load factor for 60° from the load factor chart is 1.154. Multiply the load factor times the minimum weight to be supported by the leg, i.e. 1,000 pounds times 1.154=1154 pounds. The rated sling capacity needed is then 2,308 (1,154x2) pounds in basket capacity to safely lift the 2,000 pound load.

Wattage to heat hydraulic oil: each 1 watt will raise the temperature of 1 gallon of oil by 1°F per hour. Guidelines for flow velocity in hydraulic lines: 2 to 4 ft/sec = suction lines; 10 to 15 ft/sec = pressure lines up to 500 psi; 15 to 20 ft/sec = pressure lines 500 – 3,000 psi; 25 ft/sec = pressure lines over 3,000 psi

Hydraulic Force - Engineering ToolBox

The force produced on the rod side (1) of a double acting hydraulic piston - can be expressed as. F 1 = P 1 (π (d 2 2 - d 1 2) / 4) (1). where . F 1 = rod force (lb, N). d 1 = rod diameter (in, mm). d 2 = piston diameter (in, mm). P 1 = pressure in the cylinder on the rod side (psi, bar). The force produced on the opposite of rod side (2) - can be expressed as

MODULE 4 - LIFTING AND RIGGING - Home | FEMA.gov

n If a load is suspended at its CG, it can be turned in any direction with little effort. n If load is lifted to the right/left of CG, it will tilt at an angle. n If a load is lifted below its center of gravity, the weight of the load will be above the lifting point, and the load will tip over. n Important that loads be hoisted above the load…

Feb 10, 2011· Without checking the calculations, some discrepancies are clear:- First, Guy's suggestion DOES take into account the weight of the scissor arms. Second, "apples and oranges" comes to mind, because Guy's suggestion shows the horizontal force, and HMCK's suggestion shows a force aligned with the inclination of the scissor arms.

Calculate Forklift Attachment Capacity | Cascade

Normally, an attachment tends to move the center of gravity of the combined truck and load forward. It does this by adding its own weight to the load side of the fulcrum, and by moving the truck's load center forward. The farther forward the center of gravity moves, the smaller the load weight must be and the more likely the truck is to tip ...
