KL11 Forklift Seat Supplier for Forklift Builders and Distributors176mm Slide With a Longer Rearward Travel
KL Seating supplies the KL11 forklift seat to forklift builders and truck converters that specify a seat for every truck on the line, and to distributors and importers that keep replacement seats for trucks already working. KL11 is a mechanical suspension seat set for operators from 50 to 130 kg, with 176 mm of fore-aft slide and a black PVC cover.
The slide is the figure that sets KL11 apart on the forklift range. It is split into 80 mm forward and 96 mm rearward, so the seat has more room to move back than to move forward. Slide rails, a seat belt and a micro switch are available as options, and the seat is offered inside our OEM and ODM service for builders who need the base or the option set changed.
Send the truck model, the free space in front of and behind the seat position and the operator weight range, or photos of the seat you want to replace. We reply with the KL11 parameter sheet and a fit statement that names anything that does not match.

The published sheet does not carry the suspension travel, the backrest range, the overall dimensions, the seat weight or the mounting-hole spacing for KL11. We give those items only from the factory, in the reply to your enquiry and listed against the model number. We do not borrow them from KL01 or any other model, and purchasing should place the order against the sheet that comes back with the reply.
Fore-Aft Slide: How the 176 mm Divides Into 80 mm Forward and 96 mm Rearward
KL11 slides 80 mm toward the pedals and steering column and 96 mm back toward the rear of the cab. The total, 176 mm, is the longest fore-aft figure published on our forklift range, and the rearward share is the larger of the two.
The two figures are published as separate forward and rearward values. How they sit against the bolted base position on a given truck is confirmed in the reply with the parameter sheet.
That layout suits cabs where the operator's working position sits toward the front of the available floor and the free space opens behind the seat. Builders see it on trucks where the seat is mounted close to the pedal group and the rear panel or counterweight side leaves more clearance. Distributors see it when the seat on the truck has a long rail with most of the travel behind the middle.
Three points define the slide on KL11
- The forward 80 mm limits how close the operator can come to the pedals and steering column.
- The rearward 96 mm sets how far the seat can retreat for taller operators or for entry and exit.
- Slide rails are an option on the seat, so the rail arrangement is stated with the order.
Where a truck has more room in front than behind, the split points to a different forklift model, and the comparison table further down names the options.
Cab Fit Procedure: Measuring the Seat Position for an 80 and 96 Split
The slide figure is checked against the truck in four steps, and each step uses a measurement you can take from a drawing or from the truck itself.
- Mark the base position.Take the seat position on the floor plate as the reference point for both measurements.
- Measure forward.The free distance from the zero point to the nearest part in front of the seat, normally the pedal group or the steering column, taken at the height of the seat cushion.
- Measure rearward.The free distance from the zero point to the nearest part behind the seat, taken with the backrest in its working position.
- Compare each distance with its own figure.The forward distance is read against 80 mm and the rearward distance against 96 mm. Never add the two measurements together before comparing, since a surplus on one side gives no room on the other.
Each figure is read against its own value. The two are never added together.
| Front 80 mm or more, rear 96 mm or more | Both figures are at or above the published values. The reply confirms the full 176 mm against your truck. |
|---|---|
| Only the front is below 80 mm | The reply states the usable travel in that direction for your truck; the engineer decides whether to stop the slide there or look at another model. |
| Only the rear is below 96 mm | The reply states the usable travel in that direction for your truck; the engineer decides whether to stop the slide there or look at another model. |
| Front and rear both below | The reply states the usable travel in each direction for your truck; the engineer decides whether to stop the slide there or look at another model. |
The reply states the result for each direction. If both distances are at or above the published figures, the full 176 mm is usable on that truck. Distributors without a drawing can read the same two distances from the rails on the old seat. The rail length and the old seat's position on its rails show how much room the truck gave it in each direction, and a photo of the rails from the side is enough to start.
Operator Weight Band: 50 to 130 kg on Mechanical Suspension
KL11 uses mechanical suspension and takes operators across a 50 to 130 kg band. The suspension is adjusted to the weight of the person in the seat, and the band is the range across which that adjustment is made.
Suspension travel
The suspension travel of KL11 is not published. We confirm it from the factory when you enquire, and we send it with the parameter sheet so that the free height under the overhead guard can be checked against a real figure. The method used to set the seat to weight is confirmed in the same reply.
Outside the band
If an operator weight falls outside 50 to 130 kg, the reply moves to the forklift model whose band covers it, and names it. YY53 and YY03 are listed from 40 to 120 kg, which is the route for lighter operators. The forklift seat manufacturer page lists the bands of all six forklift models side by side.
Two buyers use the band differently.
Forklift builder
A forklift builder fixes the band at the specification stage. It takes the lightest and the heaviest operator that the truck is sold for and checks that both fall inside 50 to 130 kg. A truck specified for a narrower range sits well inside the band, and a truck sold into a market with heavier operators needs the upper end.
Distributor
A distributor supplying shared or rental trucks reads the band against the fleet. Operators who change between shifts each set the seat to their own weight, so the whole fleet from the lightest to the heaviest has to sit inside the band.
Weight Band and Slide Rail Combinations: Four Ways to Specify KL11
The weight band and the slide rails are ordered together, because the rail arrangement changes how the seat is fixed to the truck while the band changes how the suspension is set. Four specifications cover most of what builders and distributors send.
The first row is the case the 80 and 96 split is made for. The second row is a builder choice that must be written down with the order, since the slide is an option on the seat and the factory does not assume it. Belt and micro switch lines add to either of the first two rows.

What the reply asks for
The seat belt and the micro switch connect to the truck, so the reply asks for the connection detail before it confirms the option set. A line such as the one above on the enquiry is enough for the first reply to carry a single confirmed configuration. If you already have a truck model and an operator range, send both now. The reply names the combination and the figure that limits it.
Option List: Slide Rails, Seat Belt and Micro Switch on a Black PVC Cover
KL11 is listed with a black PVC cover. Three options are on the sheet.
Slide rails
Give the seat its 80 mm forward and 96 mm rearward travel
Seat belt
Restraint fitted to the seat
Micro switch
Switch that senses the operator in the seat
| Option | Role on the truck |
|---|---|
| Slide rails | Give the seat its 80 mm forward and 96 mm rearward travel |
| Seat belt | Restraint fitted to the seat |
| Micro switch | Switch that senses the operator in the seat |
Photos show the sample seat; the option set is listed in the table.
Armrests, headrests and an electronic lock are not listed for KL11. Fabric is not listed for this model either. A truck that needs one of those features moves to the model that lists it, and the forklift seat manufacturer page shows which models do.
Shock Absorber Mechanical Analysis: How the KL11 Suspension Is Checked
The shock absorber of every mechanical suspension seat on our forklift range goes through mechanical analysis in the testing center, and KL11 is one of them. The analysis measures the force behavior of the shock absorber as a component, separate from the seat around it.
The result serves one purpose. It is used to confirm that the suspension of KL11 and the 50 to 130 kg band work together, so that a seat set to a given operator weight behaves as the band says. Shock absorber analysis is one of the items on the testing center's list.
- Does not replace the free height measurement under the overhead guard.
- Does not replace the slide distances. The cab checks remain with the engineer.
Frame and Base: CAE Analysis, Precision Stamping, Robotic Welding and 3D Scan
The frame and the base are the parts of KL11 that meet the truck, and they pass through four steps in sequence.
CAE structural analysis
Done at the design stage. It examines how the frame carries load before any part is formed.
Precision stamping
Forms the frame and the base on an automated line.
Robotic welding
Joins the frame at a robotic welding station.
3D scanning
Records the bottom hole positions and the outer dimensions of the frame and compares them with the design data.
How the scan data comes back to you
The 3D scan gives the mounting data a practical use. The values it records for the base are what we return to you as the model's parameter sheet, and a customer who sends a hole pattern gets it compared with the KL11 base. Where a truck needs a different pattern, the change goes to the R&D center through the ODM route, and the changed base runs through the same stamping and welding steps.
Rails and floor mounting
The slide rails sit on the base, so the base check serves the rail arrangement as well as the floor mounting. The seat fitment compatibility guide lists the measurements to take on the truck.
Production Base: Foam Molding, Assembly and the MES Record
KL11 is made in our 35,000 m² production base by a team of 180+ employees, within an annual capacity of 500,000 seats across all product families.
The path of a KL11 runs through three stations:
Foam molding line
The seat cushion and backrest are formed on the foam molding line.
Stamping and welding
The frame and base are stamped and welded, as described in the section above.
STATION 3Assembly
The suspension is fitted at assembly, together with the slide rails and the options selected on the order.
Built since 2007 · KL Seating brand since 2016
The MES system covers R&D, purchasing, production, quality inspection, warehousing and delivery, and KL11 is recorded on the same chain as the rest of the forklift line. Pressure distribution comfort testing is applied to the cushion, which gives a view of how load spreads across the seat surface during sitting.
Fit Data Package: What to Request Before Installation Is Confirmed
Because several KL11 values are not on the published sheet, the order of requests matters. The items below are what a buyer should ask the factory for, and what we undertake to return in the reply.
| The KL11 parameter sheet | The document the order is placed against. |
|---|---|
| The suspension travel | Required for the free height check under the overhead guard. |
| The mounting-hole spacing | Compared with the truck floor plate or the base of the old seat. Any drawing held at the factory for the model is requested at the same time. |
| The overall dimensions and the seat weight | Needed for the cab envelope and for freight planning on the buyer's side. |
| The backrest range | Compared with the clearance behind the seat in the cab. |
| The certificate copies | ISO 9001:2015, CE, RoHS and REACH, filed with the supplier record. |
We do not fill an unpublished value from another model. Each value comes from the factory, and the reply lists them against KL11. A builder can place the list against the cab drawing and a distributor can place it against the old seat, and each can confirm the fit item by item before anything is ordered.

Choose KL01
When the truck needs fabric, a published suspension travel figure or an even forward and rearward split.
Choose YY03
When the truck needs 40 to 120 kg operators or takes suspension as an option.
Choose YL01
For a cab whose longer travel sits in front, with 90 mm forward and 60 mm rearward.
Mechanical suspension is the system on KL11. Seats with air bag suspension belong to the agricultural range, and the suspension seats page explains how the suspension types are organized.
Supply Routes: OEM and ODM for Builders, Wholesale and Private Label for Distributors
Our OEM and ODM service is part of how the company supplies seats, and KL11 is supplied inside it.
Forklift builders and truck converters
A builder sends the truck drawing with the seat position, selects the option set and states any change to the base or the rail arrangement.
Structural changes go to the R&D center, which works through the ODM route, and the modified seat follows the stamping, welding and assembly steps described above.
Distributors and importers
A distributor sends photos of the seat on the truck, or the truck model, and receives the match for KL11.
A distributor who wants the seats under its own brand, or as part of a bulk supply range, says so in the enquiry, and the model, options and cover go on the same line.
The OEM and ODM seat manufacturer page describes the process.
Certificates and Factory Visit: Documents and Access for Supplier Approval
