Who we supply

Buyers We Supply as OEM and ODM Seat Manufacturer: Machine Builders, Distributors and Converters

YS15 excavator seat, typical of the seats specified by machine builders

Machine builders

Forklift, excavator, loader, roller, tractor, harvester, seeder, sprayer and lawn mower manufacturers form the core of the customer base. The contact is usually a component or cab engineer who owns the fit of the seat, working with a purchasing manager and a supplier quality engineer who handle supplier approval.

  • The engineer needs mounting-hole dimensions, operator weight range, adjustment travel and suspension data.
  • The supplier quality engineer needs certificates and a factory to visit.

This page carries both.

YJ03 tractor seat, a model distributors hold as a replacement seat

Distributors and importers

They hold replacement seats for machines already in service and build catalogues by machine family. They start from the old seat: photos, overall dimensions and mounting-hole dimensions.

The standard models and their options cover most of these requests, and the models pages carry the published parameters. Distributors who want the models under their own brand or as a bulk supply range are covered on the private label and wholesale seats page.

YY61 lawn mower seat, a model supplied to converters and rebuilders

Machine converters and rebuilders

Teams that refit trucks and machines with a different seat send the mounting pattern of the machine and the operator weight range, and receive the models that match.

Shipments go to Asia (50% of exports), the Americas (30%), Europe (10%) and other regions (10%). The company has made seats since 2007 and has used its own brand, KL Seating, since 2016.

Three entry routes

OEM and ODM Seat Programs: Three Entry Routes From Standard Model to Customer Drawing

The three routes differ in what the buyer sends and what comes back.

01 Route 1 · Standard model with options
KL01 forklift seat in side view, the standard model for Route 1Standard model

Route 1: a standard model with options

You send

The machine builder sends the machine type, the mounting-hole dimensions and the operator weight range.

We return

The matching models with their published parameters and the option list of each model. Options are chosen from suspension, slide rails, armrests, headrest, seat belt, micro switch, electronic lock, steering mechanism and cover material, depending on the model.

This route needs no design work. The buyer compares the returned parameters with the machine and selects.

02 Route 2 · Nearest standard model, modified
KL01 forklift seat in side view with a tracing sheet marking the change, Route 2 Base model + change

Route 2: the nearest standard model, modified

You send

When the machine needs a different mounting-hole pattern, a different option set, a different cover or a different suspension setup, the buyer names the nearest model and states the change.

We return

The independent R&D center evaluates the change against that model, and we reply with the evaluation.

The model stays the base, and the change is made on it, so the machine builder's configuration is a variation of a known seat.

03 Route 3 · The machine builder's own drawing
YQ50 construction seat faded behind the customer drawing sheet, Route 3Customer drawingSchematic

Route 3: the machine builder's own drawing

You send

A builder with a finished seat design, or with a specific installation space, sends a drawing or a written specification. For a new structure or for a new mounting-hole fit, the buyer provides the drawing or the installation-position dimensions.

We return

The R&D center evaluates them. Our R&D center works with CAE structural analysis, 3D scanning, pressure distribution comfort testing and modular seat design. After evaluation, the seat follows the production route described below.

The three routes share the same factory. A seat from Route 1 and a seat from Route 3 pass through the same forming, stamping, welding and assembly stages, and the same MES record chain covers both.

Tell us in the enquiry which route you are on. If you are unsure, send the machine details and the old seat photos, and we reply with the route that fits.

Send drawings or machine details
Configurable options

Configurable Options by Seat Product Line: Suspension, Slide Rails, Armrests, Headrests, Belts, Locks and Covers

Options are listed by model in the parameter sheets. A dash means the sheet does not list the item for that model; we confirm it when you enquire.

Fit and electrical check

Fit and Electrical Check: Mounting Holes, Weight Band and 24 V Across the Four Product Lines

Before a seat goes on a machine, three things are matched: the mounting holes, the operator weight band and, for air bag models, the supply voltage.

Mounting holes

TractorThe YY08 drawing carries a mounting-hole mapYJ03, KL03
Lawn mower—YY60, YY61, YY70

When you send the mounting-hole dimensions of your machine, or of the seat on it, we compare them with the published dimensions of the models whose weight band and fore-aft travel also match. 3D scanning records the position of the mounting holes and the outer dimensions of the frame of a built seat, and the result is compared with the design data. The comparison is returned to you as the model parameter sheet.

The forklift detail is on the forklift seats page, and the measuring guide is on the seat fitment compatibility page.

Weight band

Operator weight settings are published per model. KL01 and KL11 cover 50 to 130 kg, YY01 covers 50 to 120 kg, YY03 and YY53 cover 40 to 120 kg, and YJ03 covers 50 to 130 kg. YL02 and YS15 cover 50 to 130 kg, and YS2-8 covers 50 to 120 kg.

24V

24 V on air bag models

YJ03 and KL03 are air bag suspension models and run on 24 V. The YJ03 drawing marks a 24 V air pump motor. Send the voltage of your machine, or check the voltage of the seat now fitted, and we reply with the confirmation. The air suspension seats page carries the air bag models.

Production route

Production Route From Drawing to Assembled Seat: Foam Molding, Precision Stamping, Robotic Welding and Assembly

An OEM or ODM seat passes through four stages in our own factory, each one on a defined line.

Industrial plant building, placeholder for the foam molding line
Foam molding
Stage 1

Foam molding

Seat cushions and backrests are formed on the automated foam molding line.

Orange sparks in the dark, placeholder for the precision stamping line

Stage 2

Precision stamping

The frame and base parts are stamped on the precision stamping line.

Stage 3

Robotic welding

The frame is welded at the robotic welding station. When a design change affects the base, the changed base goes through the same frame stages.

Hands working on a mechanical assembly, placeholder for the assembly line
Assembly
Stage 4

Assembly

Suspension, slide rails and the options the machine builder selected are fitted at assembly. This is where a Route 1 or Route 2 configuration comes together.

One record chain

MES covers research and development, purchasing, production, quality inspection, warehousing and delivery, so an OEM seat follows the same record chain as a standard model.

What a drawing specifies

Seat drawings carry the requirements the production route works to. Take the YQ40 as an example. The YQ40 drawing requires:

  • stitching with thread of not less than 30 N and a stitch pitch of 3 to 5 mm;
  • rust treatment of the frame and exposed parts;
  • welded assemblies without misalignment, cold welds or missed welds;
  • the headrest, backrest, armrest, front and rear height, slide adjustment and shock-absorbing lock to adjust smoothly and reliably.

These are drawing requirements. The YQ40 and YQ50 drawings also carry a mounting-hole map. You can ask for the drawing of a model and put it next to a sample. Drawings are issued by model on request, and the model parameter sheet is the reference for values. More drawing detail is on the construction machinery seats page.

Validation

Validation Items and Test Objects: CAE Frame Analysis, 3D Scan, Cushion Pressure Test and Shock Absorber Analysis

The testing center covers 300+ m², with 20+ test devices and 30+ test items. Each test item below has its own test object.

300+m² testing center
20+test devices
30+test items
CAE structural analysis of a seat frame on screen
Pressure distribution test on a seat cushion

CAE structural analysis

Object: the seat frame

It runs at the design stage and is used to check how the frame carries load, including for a modified or new frame.

3D scanning

Object: the built seat

It records the mounting-hole position and the outer dimensions of the frame, and the result is compared with the design data.

Pressure distribution comfort test

Object: the seat cushion

It evaluates how the cushion distributes pressure under a seated operator. We publish no values and make no durability claim.

Shock absorber mechanical analysis

Object: the shock absorber unit

The object is the shock absorber unit of the mechanical suspension models: KL01, KL11, YY53 and YL02. The result is used to confirm the fit between suspension travel and weight setting.

For a modified model, these items are the checks the R&D center draws on, and the buyer sees the result in the parameter sheet returned. A factory visit can be booked in advance through [email protected], and the visit includes the testing center. The seat quality testing page describes the testing center in full.
