Estimating Passenger Traffic**
Calculating expected traffic flow is key to sizing the lift correctly and avoiding delays.
– **Number of Floors:** More floors usually mean longer travel times & potentially more lifts are needed.
– **Number of Users:** Estimate the highest number of people who will use the lift during busy times. In homes, this is based on apartment count. In offices, it’s often tied to total employees.
– **Peak Period Frequency:** How often will the lift be called at its busiest? This affects desired wait times & throughput.
– **Desired Waiting Time:** What wait time is acceptable for users?
Shorter waits often require faster lifts or more of them. Professional lift consultants frequently use advanced traffic analysis software to model these situations and suggest the best number, speed, and capacity of lifts.
**2. Understanding Lift Regulations and Standards**
Lift installation isn’t something you can handle casually.
It is strictly regulated to ensure passenger safety. Navigating these rules is a vital, unavoidable part of the process.
**2.1. Local Building Codes and National Standards**
Every area has specific building codes that regulate lift installation. These codes address everything from shaft construction & fire ratings to electrical safety & accessibility.
– **National/International Standards:** In many countries, specific lift standards are adopted, such as the EN 81 series in Europe, ASME A17.1/CSA B44 in North America, or local equivalents. These standards detail the design, construction, installation, and testing requirements for lifts.
– **Local Authority Requirements:** Your local planning department and building control office have specific application steps, inspection schedules, and approval processes.
Engaging with them early can prevent costly rework. Get to know these standards early, or better yet, ensure your chosen lift consultant & installer are fully familiar with them. Non-compliance can lead to hefty fines, project delays, or even the lift being unusable.
**2.2. Accessibility Requirements (DDA/ADA)**
Making the lift accessible to everyone is not just good practice—it is often a legal requirement.
– **Disability Discrimination Act (DDA) / Americans with Disabilities Act (ADA):** These laws, along with similar ones elsewhere, require specific features to ensure accessibility for people with disabilities.
– **Key Accessibility Features:**
– **Door Width:** Wide enough for wheelchairs.
– **Cab Dimensions:** Large enough for a wheelchair & an attendant, or even several wheelchairs.
– **Control Panels:** Placed at reachable heights, with tactile buttons and often Braille.
– **Audio Announcements:** Voice announcements for floor levels.
– **Visual Displays:** Clear visual indicators of floor numbers and direction.
– **Emergency Communication:** Accessible emergency call buttons and two-way communication systems.
– **Handrails:** Often required for stability. Ignoring accessibility requirements is not an option & will result in non-compliance.
**2.3.
Fire Safety & Emergency Preparedness**
Lifts play a key role in fire safety plans, especially in tall buildings.
– **Fire Rating of Shafts and Doors:** The lift shaft must be built with fire-resistant materials, and landing doors must meet specific fire-resistance ratings to stop fire from spreading.
– **Firefighter’s Lift (Fire Service Lift):** In many multi-story buildings, at least one lift is set aside as a firefighter’s lift. This lift has better fire resistance, a dedicated power supply, and controls that let firefighters take priority during an emergency.
– **Emergency Lowering and Rescue:** Lifts must have ways to safely descend if power fails and strong procedures for rescuing trapped passengers.
– **Emergency Power Supply:** A backup power source, such as a generator or UPS, is often needed to keep emergency lighting & communication systems working, & possibly to let lifts go to a specific floor before stopping.
– **Evacuation Procedures:** Lifts are generally not used for evacuation during a fire, except for designated firefighter’s lifts or specific evacuation lifts in rare cases. However, they must be designed to safely return to a set floor & open their doors before shutting down during a fire alarm.
**3. Exploring Different Lift Technologies**
The lift industry has changed a lot. Knowing the different technologies available will help you pick the best option for your project.
**3.1. Traction Lifts (Geared and Gearless)**
Traction lifts are the most common type for passenger transport in medium to high-rise buildings.
They use ropes or belts and counterweights.
– **How they work:** The lift car and a counterweight are linked by ropes that run over a sheave driven by an electric motor. The counterweight balances the car’s weight, cutting the power needed to move it.
– **Geared Traction Lifts:** Use a gearbox attached to the motor to turn the sheave. They are generally slower and less energy-efficient than gearless types but can be more cost-effective for lower-speed, lower-rise uses.
– **Gearless Traction Lifts:** Connect the motor directly to the sheave, removing the need for a gearbox. This makes them faster, quieter, more energy-efficient, and requiring less maintenance.
They are the top choice for high-speed, high-rise buildings.
– **Machine Room (MRL) vs. Machine Room Less (MRL):**
– **With Machine Room:** Traditionally, traction lifts needed a separate machine room above or beside the shaft to house the motor, control panel, and other equipment.
– **Machine Room Less (MRL):** Modern gearless traction lifts often fit the motor and controls right inside the lift shaft, usually at the top, removing the need for a separate machine room. This saves valuable building space and can lower construction costs. MRLs are becoming more popular for new installations.
**3.2.
Hydraulic Lifts**
Hydraulic lifts are driven by a piston that moves inside a cylinder, pushed by hydraulic fluid.
– **How they work:** An electric motor pumps hydraulic fluid into the cylinder, pushing the piston and the lift car upward. To go down, a valve releases the fluid back into a tank.
– **Applications:** Usually used for low-rise buildings (2-6 stops) & for heavy-duty tasks needing high lifting capacity.
– **Advantages:** Lower initial cost, less overhead space needed (though pit depth may be similar), good for heavy loads.
– **Disadvantages:** Slower speed, less energy-efficient (especially going up), risk of oil leaks, sensitivity to fluid temperature, can be noisier due to the pump unit.
– **Machine Room:** Hydraulic lifts always require a machine room for the pump unit, motor, and fluid tank, which can be placed farther from the shaft than with traction lifts.
