Machine Room-less Elevators

  • Features latest technology with gearless “permanent magnet” systems.
  • Motors mounted on guard rails, reducing space requirements.
  • Best suited for low to mid-rise buildings (4-6 stories).
  • Energy-efficient design limits heavy load capacities above 5000 lbs.

Conventional Elevators

  • Utilize a governor and conventional ropes with coated-steel belts for operation.

Elevator Safety Features

  • Governor: Engages safety mechanisms to halt the car in emergencies.
  • Safety Device: Installed in the cab frame, it slows the car in overspeed situations.
  • Limit Switches: Automatically stop the car within limits, independent of the operating device.
  • Counterweight: Balances the car weight, typically matching the car weight plus 40% of its capacity.
  • Buffer: Absorbs impacts at the lower travel limits.

Lifting Mechanisms for Elevators

  • Traction:
    • Utilizes geared AC or DC motors suitable for buildings up to 1000 feet.
    • High-speed systems may involve costly induction motors.
  • Hydraulic:
    • Economical solution for 2-7 story buildings.
    • Employs pistons to elevate the car but carries risks of soil contamination from hydraulic fluid.

Dumbwaiters

  • Small lifts designed for transporting food and utensils between floors in various settings.
  • Made from stainless steel to withstand steam and hot food.
  • Capacity begins at 20 kgs; dimensions range from 1.5' x 1.5' to 3' x 3' or larger.
  • Requires minimal additional space for installation.
