Holeless hydraulic elevators are also known as?

  1. Standard Hoist Assembly

  2. Inverted Jack Assembly

  3. Vertical Lift Assembly

  4. Compact Hydraulic Assembly

The correct answer is: Inverted Jack Assembly

Holeless hydraulic elevators are also referred to as inverted jack assemblies. This terminology derives from the mechanism used in these types of elevators. In a holeless hydraulic system, the hydraulic jacks do not require deep holes for installation. Instead, they are typically mounted above ground level, utilizing a configuration that allows them to operate efficiently without a traditional pit. The inverted jack assembly design enables the elevator to take up less space and simplifies installation, making it an ideal choice for buildings where space is limited or where drilling for deep pits is not feasible. This contrasts with other types of hydraulic elevators that necessitate traditional hoisting mechanisms that involve extensive underground work. Inverted jack assemblies deliver reliable and smooth operation while accommodating modern architectural demands.
