Dock Pedal Stroke Adjustment

Prerequisites

Overview

The table dock hook operates on the over-center principle. This is implemented by fixing one end of the hook to a cam on a shaft. When the force on the hook at its point of attachment to the cam is on the opposite side of the shaft as the hook end, this force will tend to keep the hook in the docked position. When the point of force is moved over-center of the shaft centerline, the force will no longer act to keep the hook retracted, and the spring loaded cam will extend the hook to the undocked position. See Figure 1. Two style table adjustments are currently in the field. The type table you have is determined by manufacturing date. Choose the procedure appropriate for your table style.

1 Tables Manufactured Before April 2002

Procedure

  1. Remove all outer and inner trim covers from sides of Patient Transport.
  2. Tighten or loosen the stroke adjustment screw as required so when the dock pedal is fully depressed during the docking operation, the hook cam mechanism just goes over-center. See Figure 2.

Procedure

  1. Remove the hatch at the rear of the table for adjusting the undock cable. See Figure 3.

    Figure 3. HATCH REMOVAL

  2. Loosen the Screw (Counter clock wise) until the table undock easily when the pedal is pushed. (This will tighten the cable pulling the lever down). See Figure 4.

  3. When finished, tighten the lock nut and reattach the cover. See Figure 3.
