Resumen del manual
In both cases, an experienced spotter must be positioned at the propeller to protect it, because of the proximity of the spinner tip to the airplane door. Beech 1900 1. The Mobilift should be moved towards the aircraft in line with the door, and stopped when lift post A is 10 to 12 inches away from the spinner tip. 2. Spinner must not project inside of a line drawn from lift post A to lift post B. (If it does, it could be damaged by the handrail as the lift is raised.) See drawing below. 3. The bridge ramp will extend to cover the distance to the sill. When deploying the bridge ramp, bring it in above the support arms for the door cables until it sufficiently overlaps the sill and then lower it down. The spotter must watch ramp, spinner and air stair cables during this process. The cables may be need to be held apart to allow the ramp to pass. Reverse this step by raising the ramp up clear of the support arms before retracting it. - 14 - Fairchild Metro With the Metro proceed as follows, referring to diagrams at the end of these instructions: 1. Station an experienced person at the propeller to be sure the lift does not touch the blades or spinner. 2. The purpose is to get the lift pointing at the door, but sitting at an angle of about 10o . In order to do this, lift post A must be about a foot ahead of the spinner tip - that is between the spinner and the plane. 3. One blade of the propeller should be set at 5 o'clock (when facing the spinner) to allow the right shroud to sit between the blades once the lift is in position. 4. The lift is brought to the plane door on a curve around the spinner. See the path of movement in the diagram. Do not contact the spinner with the lift post A. The shroud point C will clear the outside propeller blade by about 3 inches as it moves past. As the lift is being moved, watch the blades to avoid contact with the shroud on the right side of the lift. The shroud will sit exactly between the two propeller blades when the lift is in position. 5. The spinner must not project inside a line drawn from lift post A to lift post B. (If it projects in, it will be hit by the deck handrail when the lift is being raised, which could seriously damage the spinner.) 6. The lift is now ready for use with a wheelchair and can be operated as described in the manual. 7. Note that the guard person remains at the propeller through the entire process to ensure that the lift does not contact the plane while the deck and ramp are moving. 8. The bridge ramp will go into the door on an angle (the ramp moves side to side to allow this). The spotter should watch and help guide it into place if necessary. Watch the ramp handrails, not just the ramp end. Remember to get 3 full inches of overlap onto the sill. It may be necessary to hold the air stair cables apart to allow the ramp to pass. 9. Use the same path of travel when moving the lift away from the plane - again guarding the spinner and propeller. 10. It is strongly recommended that the operator take time to practice this before doing it with the additional pressure of a short turn time and a passenger waiting. - 15 - Fairchild Metroliner Path of travel follows lift post A Mobilift positioned for use 8. GENERAL OPERATING NOTES: - 16 - a) When cranking the lift, the operator should maintain a slight outward pull on the crank handle. This ensures the handle does not tend to fold while cranking. b) When cranking the lift up, the more weight there is on it, the harder it will be to crank. Cranking the deck down will feel about the same as cranking up because of the patented load activated braking system. The brakes are actually applied by the load on the deck, so increased load on the deck makes it harder to crank down. This is an essential safety feature of the drive system. c) The braking system is very reliable, but additional safety is provided by folding the hand crank, which locks the drive mechanism. This is why the hand crank must always be folded when the lift is not actually being cranked. d) All of the controls on the lift were designed for simplicity, reliability, and ease of use by an operator wearing heavy mitts in cold weather. Critical components of the lift have been tested to -60 degrees Fahrenheit. e) Persons in wheelchairs must feel safe when being lifted. Adaptive Engineering wheelchair lifts have an established reputation for reliability and safety. If the disabled traveler appears uncertain, the operator should assure them that each and every lift is load tested to over 3,000 lb. before it is placed in service. (This is about the weight of a mid-size car.) Also, there is no single component in the lift that can allow the deck to drop in the event of failure. The lift is designed, built and tested according to regulations governing devices that lift people. - 17 - 7. MAINTENANCE The wheelchair lift is safety equipment. It must be inspected officially at least once a year, or in high use areas, after every 500 uses. In addition, the...
