Hydraulic Lifts are elevator systems powered by hydraulic cylinders that raise and lower the car. They operate using a fluid-driven piston that moves within a cylinder. Hydraulic lifts are commonly used in low- to mid-rise buildings.

Key Features:

1. Working Mechanism:
   • A motor pumps hydraulic fluid into the cylinder.
   • The fluid pushes the piston, raising the elevator.
   • To descend, the fluid is released back into a reservoir, allowing the car to lower smoothly.
2. Space Requirements:
   • Typically require a machine room at the base of the shaft to house the pump and fluid reservoir.
3. Load Capacity:
   • Known for their high weight-bearing capacity, making them suitable for heavy-duty applications.
4. Travel Range:
   • Best suited for buildings up to 5-6 floors (about 50 feet or 15 meters) due to limitations in travel height.
5. Speed:
   • Slower compared to traction elevators, which makes them less ideal for high-rise buildings.

Advantages:

• Cost-Effective: Lower initial installation costs compared to other elevator types.
• Smooth Operation: Provides a gentle start and stop, suitable for passenger comfort.
• Durability: Simple mechanical design with fewer moving parts, leading to reliable operation.

Disadvantages:

• Space Usage: Requires a machine room and space for the hydraulic system.
• Environmental Concerns: Risk of hydraulic fluid leaks, which may pose environmental hazards.
• Energy Consumption: Less energy-efficient as the motor must work to lift the elevator.

Common Applications:

• Low-rise residential or commercial buildings
• Industrial facilities
• Freight elevators and car lifts
