PLATFORM LIFT

The unique drive and platform lift combinations of the V-1504 vertical
wheel chair platform lift allows for rapid delivery and ease of installation in respect to any architectural requirements.

The purpose of the safety brake is to stop the platform lift in the
event of a suspension cable or chain failure. The braking action is
started by a compressed spring as soon as the tension is relieved from
the suspension cable or chain. The brake lever is then rotated by the
spring and wedges a cam under the top of the guide rail. As soon as
this cam grips, the system becomes self locking, meaning the more
weight being applied on the platform lift, the greater is the braking
force. There is no adjustment possible on this brake but you have to
verify regularly if the brake lever moves freely.

To test the safety brake, you need to relieve the tension in the
suspension cable or chain. To do so, lower the platform lift on a
standing wood beam (approximately 2 x 2 x 15 inches). Position the beam under the hanger (vertical part of carriage) and not under the underpan sensor. Lower the platform lift and give about 12 inches of slack in the cable or the chain. If you have an ES-125 PLUS (chain driven unit),
you will have to pull out the chain guard and dismantle the turnbuckle
to allow this kind of slack in the chain. At this point, the safety
brake should have rotated and be ready to grab. Knock the beam down
from under the platform lift by using a long beam or bar while staying
clear off the travel of the platform. The platform should stay in place
and the suspension cable or chain should still be slack.
