A tension-loaded drive mechanism (“mechanism”) is provided for a cargo unloader. The drive mechanism includes a compressor for increasing the pressure of a fluid. The drive mechanism further includes multiple bladders fluidly connected to the compressor to receive the fluid from the compressor and expand in a rearward direction along a longitudinal axis of a cargo bed. The mechanism further includes a strap system having multiple straps attached to each bladder. The strap system further includes multiple spools configured to apply a compression counter force via the straps to the associated bladders, such that the compression counter force increases the pressure of the fluid in the associated bladders to a predetermined drive pressure threshold. The spools are further configured to dispense an associated one of the straps at a predetermined stepped payout rate such that the associated bladders apply a drive force associated with the predetermined drive pressure threshold.
