1. A Residential Elevator is an affordable solution to overcoming architectural barriers ?

True
False

Answer incorrect. Please try again.

A residential elevator is an affordable solution to overcoming architectural barriers and provides many benefits to residential construction. It allows the architect to design and maximize square footage in a limited lot size footprint by building vertically. It allows the homeowner to build for long term livability in a multi-level home with no concern of limited access to the home. A residential elevator adds value to the home by providing broad appeal to all types of home owners. An elevator also adds a component of luxury and opulence as a highly sophisticated appliance in any home.

2. Automatic door operators are required for Home Elevators ?

True
False

Answer incorrect. Please try again.

Power gate operators are not standard and would need to be put in the specification. They are easily installed, fully adjustable, acceptable for both indoor and outdoor use and has an optional battery backup. The gate width is compatible 32 inches to 48 inches, has an opening closing time of 8 seconds and a hold open time of 2 seconds to 62 seconds, adjustable according to the owners needs. Although not offered by all manufactures, some power gate operators have smart operation standard. This allows the operator to open, stop at the obstruction, close and remain in normal operation mode. The power gate operator is capable of manual pull to open or push to close without damage to the operator.

3. ASME A17.1 is the code that governs residential elevators?

True
False

Answer incorrect. Please try again.

Residential Elevators must be designed, engineered and manufactured to meet or exceed safety codes as established by the American Society of Mechanical Engineers – ASME A17.1 By pre-planning a residence for a future home elevator an architect can provide a simplistic option for installing an elevator in the future. With limited additional design planning, the hoistway pre-plan approach will save a home owner thousands of dollars in re-model if there is a change of needs regarding accessibility.

4. Wheelchair lifts are available with ACME Screw Drives or Hydraulic Drives?

True
False

Answer incorrect. Please try again.

Wheelchair lifts are available in two drive systems. Acme Screw Drive and Hydraulic Drive. The screw drive wheelchair lift travels at 10 feet per minute with emergency power lowering. Battery back up is option, which allows the lift to operate 5 full up and down cycles. The 1 HP motor requires a 115 VAC, 30 Amp, Single Phase power supply. The Hydraulic drive travels 17-20 feet per minute with a 24 volt standby battery back up standard. The 2 HP motor requires a 115 VAC, 15 Amp, single phase power supply. The drive is housed in a tower. The size of the tower required is determined by the vertical travel between the upper and lower landing. Keep in mind when designing a the placement of a wheelchair lift that the tower sticks up further than the upper landing. For example for a model designated to have a 60 inch lift the tower height is 85 and an eight of an inch. For a wheelchair lift with a travel height of 168 inches the tower height is 193 inches.

5. Automatic folding ramps are available for Shaftwaty Wheelchair Lifts ?

True
False

Answer incorrect. Please try again.

All wheelchair lifts must be installed with a pit, stationary ramp or automatic folding ramp. In locations where a pit is not a feasible option, a stationary ramp may be utilized. The stationary ramp is located at the lowest landing and provides access to the lift platform by transitioning from the finished floor to the lowest landing to the platform surface of the vertical wheelchair lift. As an alternative to the pit and stationary ramp, an automatic folding ramp can be used. The automatic folding ramp is mounted to the edge of the platform on the side of the lift accessing the lowest landing. It folds up to about a 70 degree angle when the lift is moving in the up direction and deploys itself automatically as the lift comes to the lower landing. An automatic folding ramp cannot be used in a shaftway or enclosure application, nor can it be mounted on the side of the lift that is opposite the main tower. When an automatic folding ramp is used the unit must also have a safety pan.

6. Ramps require a 1:12 slope ?

True
False

Answer incorrect. Please try again.

A vertical wheelchair lift is a perfect accessibility product when limited on space, a ramp is not feasible, constraints of a building preclude a passenger elevator, vertical travel is possible, and with budget constraints. A ramp requires a 1:12 slope, landings, railings, top and bottom clearances according to ADA 4.8. A 42 inch vertical requires minimum of 3 feet wide by 42 inches long and a landing for turning . On average a wheelchair lift requires a 5x5 clear space and can accommodate 1 inch to 168 inches of vertical travel in the same foot print. Another benefit of a wheelchair lift over a ramp is a wheelchair lift can serve multiple landings for the same path of travel in the same foot print.

7. LU/LA elevators can accommodate up to 6 stops ?

True
False

Answer incorrect. Please try again.

The LU/LA can have a 14 inch pit depth by code. Some manufacturers do offer a 13 inch pit depth. Required overhead is 118 inches or 106 inch overhead with a Restricted headroom clearance device. The LU/LA can accommodate up to six stops.

8. LULA elevators do not have to comply with ADAAG (American Disability Act Accessibility Guidelines) ?

True
False

Answer incorrect. Please try again.

LU/LA elevators were added to the ASME A17.1 elevator code on August 1, 1996. LU/LA elevators are addressed in part 5.2 of the ASME A 17.1 code. As with all elevators, LU/LA elevators must comply with ADAGG. ADAAG section 4.10.9 requires the floor space of elevator cars shall provide space for wheelchair users to enter the car, maneuver within reach of the controls, and exit from the car.

9. The Americans Disability Act Accessibility Guidelines are a result of the American Disability Act ?

True
False

Answer incorrect. Please try again.

What is the ADAAG? The Americans with Disabilities Act, or ADA, establishes design requirements for the construction and alteration of facilities in the private and public sectors. These requirements are known as the ADA Accessibility Guidelines or ADAAG. ADAAG contains requirements for new construction and alteration. The access board develops the requirements as guidelines to serve as a basis for standards enforced by the department of justice and the department of transportation.

10. ADA is a civil rights law ?

True
False

Answer incorrect. Please try again.

The ADA is a public law, it was enacted July 26, 1990. The law was established to eliminate barriers to transportation, public services, telecommunication, employment and public accommodations.
