Adjustments
The adjustments covered in this section refer only to those items where parts are not required. If new
parts are required, they will be supplied by Adaptive Engineering Inc. with detailed instructions on
installation and adjustment. If the lift has been vandalized or damaged such that welding or machining
is required, it must be carried out by qualified trades people, who should also refer to the
manufacturer's literature and discuss the repairs with the manufacturer.
1)
Lifting and Return Cables
These four cables are critical because each supports 1/8 the load of the lift. As illustrated, the
lifting cables [22] go from the main winding drum [32] up through the top of the drive shroud over
the upper lift pulleys [39], then down under the platform. If the inspection indicates need for
adjustment, contact Adaptive Engineering Inc. for detailed instructions.
2) Platform Paralleling Cable Adjustments
These four cables are critical because each supports 1/4 the load of the lift. If the inspection
indicates that the platform is not level or that the paralleling cables require adjustment, contact
Adaptive Engineering Inc. for detailed instructions.
3) Parking Brakes
The parking brakes are an important safety feature of the lift. They are a “normally on” design that
release only when the push-handles [17] or tow bar [20] are lowered.
Adjust the brake cables so they are tight enough to pull the brake cylinder clear of the tire but are
slack when the push handles and the tow bar are in the upper (braking) position.
If the brakes do not release, or drag when the push handles or tow bar are down, the cables require
tightening. Check your brakes if they do not hold the lift or release properly. Adjust each brake
release system individually (4 cables overall). Retighten all cable adjustment locking nuts.
If the brakes do not provide sufficient braking force when the push handles and tow bar are
released, the following adjustment should be performed:
a. With the tow bar and push handles released, check that each cable leading to the brake
lever is slack.
b. If one or more cables are still tight, check that there is no damage to the cables or to the
lift that may be causing this tension. Check the routing of the cables. If no damage is
present and the routing is correct, adjust the tight cable(s) until slack. Check that the
brake is still clear of the tire when the brake is released and retighten all cable
adjustment locking nuts.
