COVID-19 Notice

Preferred Elevator would like to assure our customers that we are taking all necessary steps to do our part in flattening the curve of COVID-19. We have developed a “No Family Contact” process for service, repairs and installations. Our Mechanic, who will be wearing a mask and gloves, will call you when we are at your front door and will discuss the issues or concerns you have with your unit. Our customer can then unlock the door, but there is no need to further greet the Mechanic or be present for the service, repair or installation. Please feel free to move to another part of the home while we are working. Final payment can be left for technician or can be done over the phone with our office.
We greatly appreciate your business during this time.

Elevators installed with more than 4 inches of “gap space” between the hoistway doors and the elevator car doors can pose a serious safety risk. Children may become entrapped in the space and could be seriously injured or killed. This risk can be reduced with the proper installation of space guards at each floor.

Which Drive System is Best for My Home Elevator?

Choosing an Elevator Drive System Preferred Elevator

When you choose a drive system, it’s a technical but essential process.

Today we’re going to look over three drive system options for your home elevator. When you choose one of these systems, it’s a technical but essential process. We know that residential elevators come with many customizations, and we hope to make the selection process less overwhelming. Here are the ins and outs of cable drum, hydraulic, and the MRL Overhead Cable Drum Drive system options.


Cable Drum Drive System

This popular choice is compact. It features an electric motor and gearbox that winds and unwinds heavy-duty cables to move the cab up and down as safely as possible. The rail configuration that this system uses saves space and uses a proprietary controller with serial communication and an advanced self-diagnostic microprocessor.  

A machine room is necessary to house the hoistway and machinery for this type of system because it provides easy access if there needs to be repairs or maintenance on the equipment. However, the machine room does not have to be large and can fit within your existing floor plan. In a nutshell, the benefits of cable drum drive systems are:

  • Flexibility
  • Easy Installation
  • Advanced Safety Features
  • Quiet ride

 Hydraulic Drive Systems

A cable drum and hydraulic drive system are similar. Both systems include a monorail guide, proprietary controls with serial communication, an advanced self-diagnostic processor, and require a machine room to house it. A hydraulic drive system uses a hydraulic ram and piston to move the car up and down. The advantages of a hydraulic drive system are: 

  • Smooth, quiet rides
  • Easy maintenance and repair
  • Advanced safety features 

MRL Overhead Cable Drum Drive Systems

When you opt for this drive system, you gain all of the benefits of a cable drum and hydraulic drive system while gaining the benefit of a machine room-less elevator. Fortunately, advances in elevator motor technology reducing the electric motor size, make it possible for the mechanicals of this elevator drive system to sit above the cab, in the shaftway, and does not require a separate machine room. If you own a townhome with limited space, you’ll appreciate this benefit. What’s beneficial about this system is that:

  • It doesn’t require a machine room
  • It’s ideal for smaller homes
  • It doesn’t use up a lot of energy
  • Advanced safety features
