To build and maintain passenger and freight elevators, it is necessary to have licenses issued by the Technical Inspection Authority. Therefore, as a company with many years of experience, we encourage you to use our services in the maintenance and servicing of passenger and freight elevators with hydraulic drive, among others. Our professional maintenance experts conduct technical inspections and regular equipment revisions. We work on hydraulic passenger and freight elevators from brands such as:

• Schindler,
• GMV Polska,
• Global Lift,
• HusarLIFT,
• FujiHD,
• Lift Service,
• KONE,
• Green Lift,
• and others!

Characteristics of hydraulic passenger and freight elevators

Elevator Structure

The construction of each elevator consists of:

• shaft,
• cabin moving within the shaft,
• a machine room located under the shaft,
• pits – below the lowest stop,
• overhead space – above the highest stop and the shaft ceiling,
• landings – stops or floors where the cabin stops.

Hydraulic elevators are characterized by hydraulic drive. The cabins move upward thanks to a hydraulic cylinder actuated by pressurized fluid. When moving downward, the cabin uses the force of gravity. To install a hydraulic elevator, an additional room next to the elevator shaft is required for the machine room. Hydraulic elevators are also known for their energy efficiency and low noise generation. They are an excellent choice due to low operating costs and safety. Passenger hydraulic elevators are most commonly used in low-rise residential, commercial, office, or hospital buildings and are designed for light to moderate traffic. Freight elevators, on the other hand, are used in warehouses, hospitals, stores, bakeries, or warehouses.

Advantages and disadvantages of hydraulic elevators compared to electric elevators (without machine rooms)

Feature	Hydraulic Elevator	Electric Elevator without Machine Room
Construction	Fewer parts. No counterweight. Lighter device (up to 60% lighter than electric elevators without machine rooms).	Many parts - wheels, bearings. Massive counterweight with guides. Long hoist ropes. Heavy device.
Purchase Costs	Lower by nearly 30% for 2-5 stop elevators.	Relatively higher for lower structures.
Installation	Fast, safe, and cost-effective installation. Efficient repairs.	Complicated installation lasting twice as long as hydraulic elevators. Complex replacement of ropes and other parts.
Operating Costs	Low costs for spare parts and maintenance.	High costs for parts and maintenance.
Shaft	Material-saving with at least one concrete wall. Main forces are at the bottom of the pit. No shaft dilation required. Small dimensions.	Massive, material-consuming drive, counterweight, and cabin. Shaft dilation is recommended. Large dimensions.
Speed	Often 0.63 m/s.	High, often 1 m/s.
Electric Power Consumption	Comparable or lower. The motor is switched off when moving down. Only lighting consumes energy during stops.	High consumption needed for counterweight movement. Frequency converter, or inverter, and lighting consume energy during stops.
Safety	High - no massive components. Machine room is in a separate room.	Average - increased risk during installation or maintenance. Tectonic movements and earthquakes pose a threat to the structure.
Noise Emission	No drive units, noise occurs only in a separate machine room.	Drive unit and control unit are located in the elevator shaft - may create annoying noise, especially in residential buildings.
Power Connection	Approximately two times greater than electric drive.	Usually a few kWh.
Ecology	Environmentally friendly. Material-saving, low device weight, few parts. Hydraulic fluid is 100% recyclable.	Massive shafts and heavy device. Many parts - winch, ropes, counterweight. Permanent magnets used in electric drives require a lot of energy in mining and production.

Maintenance of Hydraulic Passenger and Freight Elevators

The entire maintenance process involves a set of activities aimed at preventing and minimizing wear and tear. Equipment undergoes periodic inspections and revisions to ensure safety and proper long-term operation. Servicing and maintenance of elevators include:

• ongoing inspection of all equipment components,
• adjustments of components and replacement parts,
• cleaning of structural elements of elevators and parts,
• protection against corrosion.

Our maintenance experts provide services in:

• technical supervision,
• fault repair,
• repairs due to vandalism,
• elevator adjustments,
• lubrication and cleaning,
• refurbishment,
• replacement of worn-out parts.
