Dock Hook Tension Adjustment

Prerequisites

Procedure

Attempt to dock the patient transport, paying attention to the force required to engage the docking mechanism.

If the force to dock seems excessive, STOP and loosen hook (see next step). Verify that neither of the problem symptoms indicated in Table 2 is present.

Table 2. DOCK HOOK MIS-ADJUSTMENT SYMPTOMS
SYMPTOM	CAUSE	ACTION
Excessive force is required to depress dock pedal and fully engage dock latch. See Figure 1.	Hook tension too tight	Loosen hook one turn and retest

Excessive back-and-forth vibration of patient transport when using “TABLE UP” foot pedal at dock. Especially noticeable when table top is already in fully raised position. See Figure 1	Hook tension too loose	Tighten hook one turn and retest

note:

Hook tension adjustment is very sensitive. Never adjust hook more than one turn at a time without retesting.

If dock hook tension requires adjusting, loosen set screw and lock nut near base of dock hook, turn hook one turn, tighten set screw and lock nut, and recheck hook adjustment. See Figure 2.

Figure 2. DOCK HOOK TENSION ADJUST

note:
Do not adjust the dock hook tension more than one turn at a time. Adjusting more than one turn at a time may cause damage to internal Patient Transport mechanisms.
