HELICAL DRIVER TORQUE CHART
<br /> 5K Driver
<br /> Dealer :
<br /> Ram Jack Oregon " ) RAIIIIJACK
<br /> 850 Bethel Drive
<br /> Eugene, OR 97402
<br /> Torque Equation :
<br /> Hydraulic Motor : Pressure*displacemen
<br /> Model : ParkerTF0140BS280AAAB
<br /> T.
<br /> Gear Ratio*� *�
<br /> Displacement(in 3) : 8.6 24TT motor gear
<br /> where : Pressure = hydraulic pressure(psi)
<br /> Gear Drive : Displacement = hydraulic motor displacement(in 2)
<br /> Model : Auburn 6SB1316F14 17 motor = motor efficiency
<br /> Ratio : 16.88 '1 gear = gear drive efficiency
<br /> Torque Chart
<br /> Pressure (psi) 500 750 1,000 1,250 1,500 1,750 2,000 2,250 2,500 2,750 3,000 3,250
<br /> Torque (ft-lbs) 849 1,274 1,698 2,123 2,547 2,972 3,396 3,821 4,245 4,670 5,094 5,519
<br /> *NOTE : The torque can also be calculated at any hydraulic pressure by multiplying the pressure by the psi/torque factor for this
<br /> helical driver which is 1.698.

<br /> *NOTE : 1) Ultimate Capacity(Q u) =Installation Torque (T)x Torque Correlation Factor(K,).
<br /> 2) Capacities shown in table assumes the pile is fully braced and has no eccentric loading.
<br /> 3)A safety factor of 2 should be applied to the ultimate capacity to obtain the working load capacity.
<br /> 4) Torque rating,for 2 3/8"pile is 4,000 ft-lbs (2,356 psi).
