Does a goods lift necessarily require a machine room?

Builders and planners often ask themselves when installing a goods lift: Is a machine room really necessary? Since it takes up valuable space in the building, solutions without a machine room are particularly sought after. In this article, we explore the conditions under which a goods lift can be installed without a machine room and the factors that play a role in the decision.

Important Note: Even though a machine room may not always be technically required, local building regulations may mandate the presence of such a room. Therefore, we strongly recommend contacting the local building authority early on to clarify the applicable regulations for the planned construction project.

Why should one forgo a machine room?

Before we dive into the technical requirements, a fundamental question arises: Why would one want to forgo a machine room in the first place? Here are some of the key advantages that machine-room-less lifts offer:

Space savings

Space savings are one of the main reasons why builders and planners choose to forgo a machine room.
This is especially advantageous for retrofitted goods lifts, where no dedicated room for the drive unit and control system was originally planned. Skipping the machine room can provide significant benefits in terms of both space and costs.
In some cases, machine-room-less elevators are the only way to make the installation of a freight elevator in an existing building possible.

But even new constructions can benefit from omitting a machine room:

  • The floor plan can be designed more compactly, which reduces overall construction costs.
  • The freed-up space can be used for other purposes, such as additional storage or office space.

Reduced construction costs

Since no additional space for technical equipment needs to be planned, construction costs are reduced. This affects both the planning and the construction, as well as the equipping of the machine room, which can lead to significant savings, especially in smaller projects.

More flexible installation

Hydraulic lifts offer a crucial advantage here: Since the hydraulic unit and control system can be housed separately from the elevator, this allows for particularly flexible installation — a decisive factor, especially in existing buildings where structural conditions are often limited.

Aesthetics and design

Machine rooms installed on rooftops or in exterior areas can affect the appearance of a building. By forgoing such rooms, the building's architecture remains untouched and the overall aesthetic concept is not disrupted.

What requirements must the 'machine room' meet?

Although a dedicated machine room is not required for the goods lifts built by our company, this does not mean that the hydraulic unit and control system can be placed just anywhere. To ensure smooth operation and a long lifespan of the system, several important requirements must be met.

Let's take a closer look at the criteria the installation site should fulfill:

Restricted access

This does not mean that the installation site should be difficult for our staff to reach. On the contrary, the hydraulic unit and control system should be easily accessible for maintenance or troubleshooting to ensure smooth upkeep.

However, the situation is different when it comes to unauthorized persons: The drive unit should not be installed in publicly accessible areas, as the risk of damage would be too high. To prevent this, it is advisable to place the drive unit in a locked room accessible only to authorized personnel — such as a technical room in the basement.

If you are concerned that tenants or others might accidentally damage the system, using an additional protective cover with a padlock might be a sensible alternative. Feel free to contact us to find a suitable security solution together.

Adequate ventilation

Although our systems generate only minimal heat, the heat that is produced still needs to be dissipated. Therefore, the installation room should either be well-ventilated or sufficiently large to prevent overheating.

Fire protection regulations

Since this request has been brought to us several times: As a general rule, it is not permitted to install the hydraulic unit within escape routes. The control system also poses a potential fire hazard, which in an emergency could make the escape route impassable. To be on the safe side, you should consult with your fire protection expert in case of any doubts.

Soundproofing

It is advisable not to place the hydraulic unit in a noise-sensitive room or an open gallery. A stairwell may also be unsuitable, as the noise level can spread easily and disturb the surroundings.

If such placement is unavoidable, feel free to contact us. If necessary, we can encase the hydraulic unit with acoustic insulation mats to reduce the noise level.

Possibility of suitable cable routing

The location for the hydraulic unit should be chosen so that cable routing can be done without issues.

Ideally, the unit should be placed in close proximity to the elevator shaft to keep the hydraulic and electrical cables as short as possible, thereby minimizing installation effort.

Additionally, there should be the possibility to install empty conduits for power supply and other elevator components (e.g. safety locks, control unit).

Placement of the hydraulic unit and control system for scissor lift tables and column lifts

Where exactly can the hydraulic unit and control system be placed for a scissor lift table or column lift? Here are some important tips for optimal placement:

Scissor lift tables

For sufficiently large scissor lift tables, the hydraulic unit can be installed directly beneath the platform. This saves space but may hinder accessibility in case of a malfunction and poses a risk of water damage when placed outdoors.

In addition to internal placement, external installation is also possible, where the drive unit is placed directly next to the enclosure or in an adjacent room. Based on our experience, a hose length of up to five meters is unproblematic. For longer distances, such as 10 to 20 meters, we recommend partially piping the hydraulic line.

Placing the drive unit in the shaft next to the scissor lift table is not recommended. The larger shaft dimensions required for this would at least necessitate a one-sided platform railing or some form of spatial separation, leading to additional costs.

Column lifts

Column lifts have the advantage of requiring either no or only minimal under-clearance. The downside: It is not possible to place the hydraulic unit or control system beneath the platform.

Unlike scissor lift tables, placing the components in the shaft can be a suitable solution for a column lift if the shaft is sufficiently large. Since platform railings are already required in the direction of the lifting columns, the components can be housed in the shaft without additional costs. However, this placement has the disadvantage of limited accessibility in the event of a malfunction.

As for external placement, the column lift is no different from the scissor lift table: Placing the drive unit up to 5 meters away is easily possible. For longer distances, we recommend bridging at least part of the distance using hydraulic pipes.

With some limitations, the unit can also be mounted at the top of the column lift's guide frame, provided the shaft height is sufficient. However, access in case of a malfunction would also be more difficult in this case.
