RAMP OPERATION

Operation Notes and Details

The RA500 ramp provides vehicle access to people with disabilities (wheelchair passengers or stand- ees using other type mobility aids). The commercial oriented RA500 ramp is operated by the transit vehicle driver/attendant. Unless your transit agency has

a published policy stating that driver/attendants do not aid ramp passengers, safe entering and

exiting of ramp passengers is the responsibility of the driver/ attendant.

As stated in the Ramp Operation Safety section, all information in this manual is provided for the safety of passengers, attendants and bystanders. Recognize the seriousness of this information.

Read and become familiar with all ramp operation safety precau- tions, pre-operation notes and details, operating instructions and manual operating instructions before attempting ramp opera- tion procedures or assisting ramp passengers boarding and exiting the vehicle.

Ramp Access Doors and Interlocks

Attendants must become familiar with the vehicle ramp access door system and interlock(s), as well as the proper operation of the ramp.

Vehicle ramp access door con- figurations and operation proce- dures vary. Ensure the ramp door is fully open before activating the ramp (an interlock typically pre- vents ramp operation unless the door is fully open). Attendants and passengers must keep clear of the area in which the power door operates. Ensure the path is clear before closing the door. Be sure the door is fully closed before attempting to drive the ve- hicle (interlocks typically ensure this).

Interlocks are required by nearly all transit authorities. Vehicle interlocks typically prevent vehicle motion if the ramp is not stowed. In some cases, the ramp cannot be operated if interlock conditions are not met. Interlock require- ments may include: the vehicle transmission must be engaged in Park, the parking brake must be engaged, the ramp access door must be fully open and/or others. Multiple interlocks may exist.

Instructions for operation of inter- locks and door systems cannot be addressed in this manual due to the variety of procedures required for operating them.

General instructions for safe operation of the ramp are pro- vided. Ramp safety and ramp passenger safety information is included. It is the responsibil- ity of the attendant to properly open and close the ramp access door(s), to activate interlock(s), to properly activate the ramp power functions as well as assist ramp passengers.

Do not operate the ramp if you suspect ramp damage, wear or any abnormal condition. Dis- continue use immediately and contact The Braun Corporation at 1-800-THE LIFT®. One of our national Product Support repre- sentatives will direct you to an authorized service technician who will inspect the ramp.
