Pitless Hydraulic Elevator for Homes: 14.5 m Travel, 5 Stops

1. Is a pitless hydraulic elevator the right choice for your house?

A pitless hydraulic elevator is a hydraulic lift whose drive does not need a hole in the ground at the lowest landing. The cylinder raises the car from below, and the load it carries travels down into the floor structure rather than into the walls of an excavated shaft. Pitless, holeless and no pit are three names for the same idea, and all three describe the bottom end of the installation, not the whole of it.

That distinction is where most projects are won or lost. Removing the pit removes the excavation, the concrete work and the waterproofing below floor level, which is what makes an installation possible in a finished house. It does not remove the platform the cabin stands on, the anchoring that holds the cylinder and rails, or the room the drive needs above and beside the travel. A supplier who only talks about the missing pit has not described the job.

This page sorts your project into one of three states before it discusses anything else. The middle column is not a rejection: it means an answer is missing, and the answer usually comes from one measurement that takes an afternoon.

Pitless is not the same as builder-free. In this configuration the cylinder and the platform replace the pit, so the work moves rather than disappears: anchoring into the floor at the lowest landing, a small step or platform there, a cable route to the power unit, and fixing points along the shaft. Budget for that work at enquiry stage and the offer you receive will match the house you actually have. The wider hydraulic range sits on the hydraulic home elevator category page if you want to compare travel and stop counts first.

2. How a pitless lift works without a pit

A hydraulic lift raises the car from below. A power unit pumps oil into a cylinder, the rod pushes the car up, and a controlled valve lets gravity bring it down. Because the car is supported rather than suspended, the force runs straight down through the cylinder — which is where the pit question comes from: in a conventional hydraulic lift the car finishes its travel below floor level so that the cabin floor lands flush with the landing, and that lower position is what the pit is for.

Remove the pit and the car simply stops higher. At the lowest landing the cabin floor finishes at the top of a low platform or deck instead of at the finished floor level, and everything that would have hung below floor level stays above it. The specification for this unit names Deck floor as its floor type for exactly that reason. Nothing is excavated; a small step is built.

What the pitless version changes, and what it does not

• The cylinder carries the load vertically. A hydraulic car is pushed from underneath, so the force from the car and its contents passes through the cylinder into the structure below. That is the key difference from a traction lift, where the load hangs from ropes and the shaft top carries it.
• The cylinder length on the sheet is 2.9 m, and the travel is 14.5 m. Those two figures describe a staged cylinder arrangement rather than one straight ram, and how it is staged decides where it sits in your shaft. Ask for the cylinder and rail layout on the approval drawing and check it against the wall you intend to use. Contact our engineers.
• There is no counterweight. The drive moves the whole car and load with oil pressure, so the pump motor, 4.7 kW on this sheet, is sized for that duty directly. No counterweight frame eats shaft width, which is what makes the compact footprint possible in a house.
• The shaft still has to be built and fixed. The pit is what disappears, not the structure. Guide rails still need fixing points at intervals along the travel, and the platform and cylinder still need a load path into the floor.
• Oil is a service item. A hydraulic drive has a tank and seals, so plan for oil checks as part of routine maintenance — see section 9.
• Temperature matters if the shaft is outdoors. Hydraulic oil behaves differently when cold, and an outdoor shaft changes the duty cycle. Say so at enquiry stage so the oil and control settings are chosen for it. Contact our engineers.

One consequence is worth stating plainly, because contractors ask it first: a pitless lift on a low platform is not the same product as a lift with a shallow pit. A shallow pit still excavates and still lets the car travel below the floor. This version does not, and that is why the deck platform exists.

3. 14.5 m, 5 stops, 0 m pit: the specification in detail

The table below is this unit's specification as it stands, with the metric values converted for imperial readers. Switch between the two sets with the buttons above the table.

Values as published on this page's own specification tables. Where this page carries the same figure twice, in the side panel and in the body table, the two agree.

How 14.5 m turns into five stops on your drawing

Travel is measured from the lowest landing to the highest landing, not from the number of storeys. Divide 14.5 m by your own floor-to-floor height to get the stop count the drive can serve: at 2.9 m per level, five stops; at 3.2 m, four with room left over; at 2.4 m, five with travel in hand. Measure the section drawing rather than counting windows — a tall ground floor and two low attic levels can pass 14.5 m while the plan still shows five levels.

What this specification sheet does not state

These are the inputs no pitless hydraulic offer can be compared without, and the points at which two offers can look identical while being priced for very different machines. Ask for each in writing.

4. When a pitless lift cannot be used

Every supplier's page explains why pitless is convenient. Fewer explain where the idea stops working, which is the part a contractor can price and a homeowner can check. Work through this reverse test before you ask for a quotation; if two or more items apply, the layout has to change before the price means anything.

• The lowest landing is a slab over a basement, a garage or a car park. The cylinder pushes its load straight down, so with a suspended slab that load lands on someone else's ceiling. It is a structural question for a drawing to answer before the anchor position is fixed.
• The lowest landing is a timber deck over a crawl space. Joists and boards are designed for people walking on them, not for an anchor carrying a cylinder and a loaded car. A steel spreader and an engineer's detail can bring the floor up to the job; without them, this configuration should not be installed.
• There is not enough headroom above the top landing. Guide rails and the cylinder assembly need vertical space above the highest stop. If the ceiling is shallow, sloping or already full of ductwork, and it cannot be raised or the assembly moved, the travel has to come down.
• The household insists on flush thresholds at every level, with no platform and no builder work. The deck platform is what replaces the excavation, not a defect to be argued away. A lift that lands flush on the ground floor needs a pit, whatever a comparison table says.
• Nothing may be fixed to the walls or the floor along the route. Landmarked interiors, listed structures and some glass atriums fall into this group. A self-supporting shaft needs fewer fixing points than a masonry one, but it still needs anchoring at the ends, agreed with the building's own rules.
• Travel is longer than 14.5 m, or the layout needs more than 5 stops. That is the published limit of this specification. Exceeding it means the drive or the model changes, and the enquiry should say so at the start.
• Services run across the cylinder footprint. Underfloor heating loops, drainage runs, gas lines or a duct under the platform turn a straightforward anchor into a relocation job. Find them before the position is agreed.
• The route cannot take the equipment. The crate has to reach the house and the sections have to reach the shaft. Door widths, stair turns and crane access belong in the survey; a narrow service stair changes the delivery plan, not the product.

The three checks that settle it

Most of the items above come down to three measurements. Each takes an afternoon and each changes the answer, so do them before comparing offers rather than after.

If the first check comes back badly, the project is not over. Three routes usually remain: move the shaft so the cylinder lands over a wall, a beam or a slab on grade; add the steel detail the engineer asks for and keep the pitless arrangement; or change the configuration altogether. The 5 stop pitless lift for apartments and villas shows the same family of drive in a different shaft arrangement, and comparing the two before the survey is cheaper than discovering the difference afterwards.

5. Power supply and electrical conditions

The electrical side is where a retrofit either gets simple or gets expensive, and this unit sits on the simple side. The specification gives a 220 V, 50 Hz, single-phase supply and a 4.7 kW motor, so a house with a normal domestic board does not have to bring three-phase power in to run a lift. That one line removes the cost of a supply upgrade and, in many markets, the utility paperwork that goes with it.

What the supply has to do is carry a motor that starts under load. That is an electrician's decision on site, made from cable length, board capacity and local rules. The card below separates what the unit fixes from what your site has to confirm.

Where the power unit should live

The power unit makes a noise while the car moves, so its position is a comfort decision as much as a technical one. Keep it away from a shared bedroom wall, give it ventilation, and leave the access it needs for oil checks and seal inspection. If the shaft is outdoors, it needs weather protection as well. Contact our engineers.

Duty matters too. A hydraulic drive runs its pump every time the car travels, so a house with very frequent trips puts more hours on the machine than a holiday villa does. Say how many trips a day you expect, and the duty is checked against the drive before the order rather than after handover.

6. Cabin, doors and finish

The cabin is the part a household touches every day and the part a buyer remembers. This specification offers two cabin materials, 304 stainless steel or aluminium alloy, with automatic doors. Each carries consequences worth knowing before a finish is chosen for looks alone.

One note on weight, because it is easy to miss: every material choice above travels back into the structure. A stainless cabin is heavier than an aluminium one, and a heavier car asks more of the cylinder, the platform and the floor anchor, which is why the finish decision belongs with the survey. For the other direction this product usually goes in, the 14.5 m no-pit villa lift shows the same drive in a larger, fully finished installation.

7. Installation sequence and what it disturbs

A retrofit is judged by the condition of the house afterwards, so this section describes the sequence and the damage it does rather than the features of the machine. The short version: nothing is excavated, the floor is drilled for anchors, one area becomes a work zone, and the lift is tested and handed over.

8. Safety devices and handover checks

This specification states one safety device explicitly: an emergency stop button. Everything else that a careful buyer wants to see tested on the day of handover has to be asked for by name, because the sheet is silent about it. The list below is written the way a handover should run: each line is something to see working, not something to take on trust. Tick them off as they are demonstrated.

Two notes on how to read that list. Nothing on it is unusual: every check belongs in a normal handover, and a supplier who resists showing them is telling you something. The items left open are marked because this specification sheet does not state them, not because they are missing from the product — ask for the answer in writing.

Approval and local rules

Domestic lift rules differ by country and sometimes by state, and this page claims no certification: the specification table lists no certification line, so no standard is quoted here. Before the order, ask two questions locally: does a residential lift of this type need a permit or a registered inspection where the house is, and what evidence does the authority expect from the supplier. That is the one part of the project the lift manufacturer cannot settle for you.

9. Service, warranty and spares

The warranty on this specification is one year. What happens after that depends on the service arrangement you set up and on how well the machine was installed, so this section covers what a hydraulic home lift actually asks for over its life.

Cost of ownership on a hydraulic lift is dominated by the oil circuit rather than ropes and sheaves, and by the fact that there is no counterweight to maintain. Against that, every trip runs the pump, so trips per day is a genuine factor in how the machine ages.

10. Pitless hydraulic elevator FAQ

The questions below are the ones that come back most often from homeowners, contractors and distributors looking at a no-pit installation. Answers stay inside what this page's own specification states; where it is silent, the answer says so.

11. What to send for a quotation

An offer for a pitless hydraulic home elevator is only as good as the inputs behind it. The list below is the full set needed to fix a layout, a price and a delivery date. Send what you have; the items you cannot answer are exactly the ones we will ask about, and answering them once is faster than three times.

Commercial terms on this specification

One last point on scope: the pitless arrangement removes the excavation and moves the builder work rather than deleting it — a platform at the lowest landing, an anchor for the cylinder, fixing points along the shaft, a cable route to the power unit. Send the three measurements from section 4 and those items can be priced from the drawing instead of guessed at after the order. If the floor or the headroom rules this configuration out, say so early: a different layout is cheaper than a dismantled floor.
