Yes. Every PVE model is certified to ASME A17.7, the North American performance-based safety code for elevator and escalator systems, with certification by Liftinstituut. Each elevator is pre-assembled and factory safety-tested before shipping.
Multiple independent safety systems operate simultaneously during every ride, including car locks, electromechanical door interlocks, and mechanical safety brakes that function even without electrical power.
How a Pneumatic Vacuum Elevator Actually Works
A pneumatic vacuum elevator moves using changes in air pressure, not cables or counterweights. At the top of the transparent cylindrical shaft, turbine motors create a vacuum above the cabin. The higher atmospheric pressure below the cabin pushes it upward.
To descend, a valve slowly releases air back into the chamber above the cabin. Pressure equalizes, and gravity brings the cabin down smoothly and quietly. No hydraulic fluid. No oil. No cables under tension.
That simplicity is the foundation of the safety story. Fewer mechanical parts means fewer failure points. And because gravity always works, a power failure never leaves someone stranded mid-floor. For a complete walkthrough of the operating mechanism from vacuum creation to controlled descent, our guide to how pneumatic vacuum elevators operate covers every phase of the cycle.
The Safety Features Built Into Every PVE Elevator
Every pneumatic vacuum elevator installed by Coastline Lift includes the following safety systems as standard. They work together as layers of protection, each one independent of the others.
1. PVE Car Locks: Floor-Level Anchoring
PVE car locks are the steel lever mechanism that anchors the cabin firmly to the structural columns at each floor. During ascent, they stay closed and retracted. The moment the cabin reaches the selected landing, the locks engage and anchor the cabin precisely at floor level. The cabin does not float between stops. It is held in place until the next command is given. This precise leveling also makes entry and exit easy and safe at every floor.
2. Mechanical Safety Brakes: The Last Line of Defense
Mechanical safety brakes are physical, non-electrical brakes that activate automatically if the system detects any uncontrolled descent. On every PVE model installed by Coastline Lift, these brakes engage within two inches of any uncontrolled downward movement. They are triggered by vacuum loss, independent of electrical power entirely. If the brakes engage, the cabin anchors immediately to the structure at that point. Free fall is physically impossible.
3. Electromechanical Door Interlocks
Every landing door is equipped with an electromechanical interlock. The cabin cannot move unless every door at every floor is fully closed and latched. There is no override. All controls inside the cabin operate at 24 volts, which means there is no high-voltage wiring within the passenger area at any point during operation.
4. Automatic Gravity Descent During Power Loss
When power is interrupted, the vacuum above the cabin releases. The cabin descends smoothly and slowly to the ground floor under gravity, at a controlled, reduced speed. No battery backup is required for this. The descent is not a malfunction. It is a designed behavior built into how the system works. When the cabin reaches the ground floor, the doors open normally. The passenger exits safely. For a more detailed look at what happens during a Florida storm outage — how the valve, battery backup, and descent mechanism coordinate in sequence — our guide to pneumatic elevator power outage safety walks through the full process.
5. In-Cabin Communication
Every PVE installation includes a standard alarm system within the cabin. An optional in-cabin telephone provides two-way communication at all times. The cabin is never a sealed space with no way to reach the outside world.
6. Battery-Powered Lighting and Ventilation
Interior lighting and the cabin fan remain fully active on battery power during any power interruption. The cabin stays lit and ventilated regardless of what is happening with the main electrical supply.

ASME A17.7: The Safety Standard Behind These Elevators
ASME A17.7 is the North American performance-based safety code that governs the design, construction, operation, testing, and maintenance of pneumatic vacuum elevators. It is the applicable standard for every PVE model Coastline Lift installs, and it means the elevator meets a defined set of engineering and safety requirements verified by an independent certification body.
Every PVE unit is pre-assembled and safety-tested at the manufacturer's factory in Miami before it ships to your home. By the time the elevator arrives on-site, it has already passed a full factory inspection. The Coastline Lift installation team does not fabricate the unit from parts in your home.
They mount, connect, and commission a system that was certified before it left the factory. LiftInstitute, an independent elevator safety testing organization, certifies PVE units against ASME standards.
Florida's state elevator code aligns with ASME performance-based standards. Every Coastline Lift installation also meets Florida building code, local wind-load requirements, and the structural specifications designed to withstand high-wind conditions.
Safety Starts With Who Installs It, and Who Answers the Phone Afterward
A mechanical specification only matters if the installation is done correctly and someone responds when you call. This is where Coastline Lift's approach to safety goes beyond what any product sheet can describe.
Coastline Lift uses one certified in-house crew for every installation. No subcontractors. The same team that installs your elevator knows every component of the system. When you call with a question six months after installation, you are talking to someone who was in your home and knows your specific unit.
That matters for safety in a very direct way. In reviews of other elevator companies across Florida, the most common complaint is not about the elevator itself. It is about being stranded after the sale with no one answering. A mechanical system is only as safe as the support behind it.
Safety continues after installation.

Frequently Asked Questions
What happens if the power goes out while I am inside?
The cabin descends smoothly and slowly to the ground floor under gravity. No battery backup is required for this process. When the cabin reaches the ground floor, the doors open normally and you exit. This is a designed behavior, not an emergency response. It is how the system was built to work.
Can the elevator go into free fall?
No. Free fall is physically prevented by two independent systems. First, car locks anchor the cabin to the structural columns at each floor during normal operation. Second, mechanical safety brakes engage within two inches of any uncontrolled descent if vacuum pressure drops unexpectedly. These brakes are entirely independent of electrical power.
Are pneumatic elevators noisy?
The turbine motors operate at approximately 85 decibels during ascent, which is comparable to a household vacuum cleaner. Descent uses no power at all and is near-silent. The split-unit configuration option — where the vacuum motor is located away from the shaft — can reduce perceived noise inside the home significantly.
How do I get out if there is an emergency while the elevator is between floors?
In normal operation, the cabin will not remain between floors. If power is lost, the cabin descends to the ground floor automatically and the doors open via mechanical door locks, which operate independently of the electrical system. In the rare event of a vacuum loss requiring the mechanical brakes, standard rescue procedures apply, as with any certified residential elevator.
Is a pneumatic elevator safe for someone who uses a wheelchair?
The PVE 52 is the wheelchair-accessible model in the PVE lineup. Its 43.5-inch interior diameter and 32-inch entry accommodate a standard wheelchair with an attendant. Coastline Lift reviews the specific mobility equipment in use during the free on-site evaluation and confirms fit before recommending a model. For a broader look at what full accessibility means in a home elevator installation, our guide to wheelchair-accessible home elevators in Florida covers what to evaluate and what to confirm before choosing a model.
How often does a PVE elevator need maintenance?
Annual inspections are recommended for all PVE models. For coastal Florida installations, Coastline Lift recommends a 6 to 12 month inspection schedule due to salt-air and humidity exposure. Routine maintenance covers seal checks, filter cleaning, and safety system verification. There is no hydraulic oil to change and no cables to inspect. Residential elevator inspections in Florida must be performed by a certified elevator inspector.
What should I look for when choosing a pneumatic elevator installer?
Look for an authorized dealer for the brand being installed, ASME A17.7 compliance on the specific model, a licensed residential contractor (not a subcontracted crew), local 24/7 emergency service capability, and a written all-in quote with no hidden permitting, electrician, or framing fees.
