Suspension Seat Manufacturer for Machine Builders and Distributors: Mechanical and Air Models From 40 mm to 180 mm Travel

KL Seating builds suspension seats for forklifts, construction machinery and tractors. Eight models publish a suspension travel figure, from 40 mm to 180 mm. Mechanical suspension covers the shorter travels and air suspension covers 80 mm and 180 mm on a 24 V supply. The range sits on one travel scale below, with the operator weight band and the machine-side requirement of each model next to it.

KL Seating is a suspension seat manufacturer and supplier to machine builders who fit a seat into a cab design, and to distributors and importers who stock replacement seats for forklifts, excavators, loaders and tractors. The suspension range has two lines. Mechanical models run from 48 mm to 70 mm of travel. Air bag models run at 80 mm and 180 mm and take a 24 V supply.

Pick the travel your cab allows, check the operator weight band, and confirm whether your machine has 24 V at the seat. Those three figures select the model. Send them to us together with a photo of the seat you are replacing, and we reply with the model that fits and the figures the factory still has to confirm.

  • Eight models with published travel, 40 mm to 180 mm
  • Own foam molding, precision stamping and robotic welding, 500,000 seats a year
  • ISO 9001:2015, CE, RoHS and REACH
  • OEM and ODM for machine builders, wholesale and private label for distributors
Range on one scale

Suspension Seat Range on One Travel Scale: 40 mm to 180 mm

Each model below carries one published travel figure, listed in order of travel. The operator weight band comes from the parameter sheet. Model pages and series pages carry the full data.

Where the suspension type is not published, we list the model by travel and do not name the type. The factory confirms it on request.

Two more forklift models belong to the mechanical line without a published travel figure. KL11 is a mechanical suspension seat with a 50–130 kg weight band, and YY03 offers suspension as an option with a 40–120 kg band. We do not print a travel figure for either, so send the travel you need and we confirm against the factory data.

The YQ50 drawing marks air bag suspension together with 60 mm of seat height adjustment. The drawing carries no travel figure and no supply voltage, so YQ50 is not on the scale.

Cab clearance

Travel Selection by Cab Clearance: 48 mm to 180 mm

Travel is the vertical movement of the seat on its suspension, so the cab has to give that movement room. The scale spans a wide range. KL03 at 180 mm moves 132 mm more than YY53 at 48 mm, nearly four times the travel. At the short end, YY53 and KL01 differ by 2 mm, which is why the choice between those two is made on other data.

A selection with us runs in four steps:

You give the machine

You give the machine type and the cab or platform it sits in.

You give the travel

You give the travel of the seat now fitted, or the travel your cab design allows.

Step two sets the line:

  • A machine whose present seat has a travel of 70 mm or less points to the mechanical models, YY53, KL01 and YL02.
  • A machine with 80 mm points to YJ03, or to YY08 where the travel is the first requirement and the suspension type is confirmed by the factory.
  • A machine that needs more than the 110 mm top of the YS range points to KL03 at 180 mm.

For the 40–110 mm models YS15 and YS2-8, the travel is published as a range. Tell us the working value your cab needs and we confirm which setting applies.

You give the free space

You give the free space under the cushion and around the seat base.

Step three is the measurement buyers skip. A seat with a different travel changes how the operator sits in relation to the steering wheel, pedals and roof. Measure the old seat’s travel and the free space beneath the cushion before an order. With both figures, the model choice takes one reply.

We answer with the model

We answer with the model and say which figures come from the parameter sheet.

Operator weight

Operator Weight Band Match: 40 kg to 130 kg

A suspension seat is set for the person who sits on it, so the weight band is the second figure on the sheet. The published bands fall into three groups.

40kg

Operators below 50 kg

The lowest published band, 40 kg, belongs to YY53 and YY03 on the forklift line.

130kg

Operators above 120 kg

The 130 kg ceiling belongs to KL01, KL11, YL02, YJ03 and YS15. YY53, YY08 and YS2-8 stop at 120 kg.

50–130kg

Mixed fleets

A fleet with operators at both ends of the range names a model from the 50–130 kg group in the first message, or asks us about KL03.

Two models share 80 mm of travel and differ here. YJ03 covers 50–130 kg and YY08 covers 50–120 kg. Two models share the 40–110 mm range and differ by the same 10 kg: YS15 reaches 130 kg and YS2-8 stops at 120 kg.

KL03 has no published weight band. The factory confirms it when you enquire, so send the operator weight range with the machine details.

Mechanical line

Mechanical Suspension Seats: 48 mm, 50 mm and 70 mm

The mechanical line holds the three shortest published travels on the scale. YY53 and KL01 are forklift seats. YL02 is built for construction machinery and heavy equipment. KL11 completes the line as a forklift seat without a published travel figure.

No power at the seat. The published data for these models lists no air pump motor and no supply voltage, so the machine side has no power requirement to check for the seat. That makes the mechanical line the direct route for machines without a 24 V supply at the seat position.

The shock absorber of each mechanical model goes through mechanical analysis in our testing center, and the result is used to confirm that travel and weight band belong together. The series pages carry the full parameters: forklift seats and construction machinery seats. The range overview is on mechanical suspension seats.

Air line

Air Suspension Seats: YJ03 at 80 mm, KL03 at 180 mm

Two models use air suspension, and both are tractor seats. YJ03 has an air bag suspension with 80 mm of travel and a weight band of 50–130 kg. KL03 has air suspension with 180 mm of travel, the longest published on this site. KL03 is listed in the parameter sheet for tractors, construction machines and agricultural machinery.

Check first

Supply Check for Air Suspension Models: 24 V at the Seat Position

Underside of the YJ03 seat base
YJ03 underside

The power supply belongs to the machine. It cannot be changed from the seat side, so this check comes before the model choice for YJ03 and KL03.

What each buyer checks

  • Machine builder. Check it at the design stage. Does the cab or platform wiring provide 24 V at the seat position, and is the interface listed next to the mounting data?
  • Distributor. Check it per machine. Does the tractor in the workshop have 24 V at the seat, and did the old seat carry a pump?

What to send us

  • The voltage information of the machine.
  • A photo of the underside of the old seat where any pump or wiring sits.

We reply with the model that fits. Where the machine has no 24 V supply, the mechanical line above is the route.

Figures such as pump current and connector type are not on the published sheet. We do not print them. The factory answers each point against the electrical details you send.

Selection path

Mechanical or Air Suspension: Selection Path for Machine Builders and Distributors

Three questions put a machine on the right line. They follow the order a buyer works through.

Machine builder

Path for a machine builder

Fix the travel the cab design allows, then the supply at the seat, then the weight range of the operators. The three figures go into the seat interface specification and we confirm the model against it. Structure changes go to the research center.

Distributor

Path for a distributor

Read the travel on the seat being replaced, check the voltage on the machine, and send a photo. The answer names the model and says which figures are still open.

For these three models the parameter sheet is the source and the buyer reads the travel from it. The drawings for YS15 and YS2-8 carry some values that differ from the sheet. The sheet is the reference when we send a drawing, and the factory confirms any figure that appears in both.

If your machine needs the suspension type fixed before design freeze, ask for the factory confirmation in your first message. Model YQ40 is listed on YQ40 heavy machinery seat and has no suspension figures.

Made in our own plant

Suspension Seat Manufacturing: Shock Absorber Analysis, CAE and MES

All suspension seats are built in our own plant. Seat cushions and backrests are foam molded, seat frames and bases are precision stamped, frames are welded in the robotic welding station, and the suspension, slide rails and chosen options are fitted at assembly.

Own plant35,000m²
Employees180+
Testing center300+m²

CAE frame analysis

CAE structural analysis of the seat frame at design stage.

3D scanning

3D scanning of the base holes and frame outline, with the result returned to the buyer against the parameter sheet.

Pressure distribution

Pressure distribution testing of the seat cushion.

Shock absorber analysis

Mechanical analysis of the shock absorber on mechanical suspension models, used to confirm that travel and operator weight band belong together.

What the buyer can verify

  • The parameter sheet lists travel and weight band per model.
  • The base-hole check is returned against the sheet.
  • The plant is open to visits by appointment.
Seat base measured by a 3D scanner in the testing center

These checks run in a testing center of 300+ m² with 20+ devices and 30+ test items. The MES covers research, purchasing, production, quality inspection, warehousing and delivery, so a suspension seat follows the same record chain as every other seat we build.

Pass thresholds and sampling rates: not published.

How we supply

Supply Programs: OEM, ODM, Wholesale and Private Label

Machine builders and distributors buy suspension seats in different ways, and the supply side covers both.

OEM and ODM

Machine builders work through OEM and ODM

  • We fix the model against your drawing and mounting pattern, and structural changes go to the research center.
  • The program covers the whole product line.
  • Cover material, options and mounting pattern are agreed in the same file as the model.
Wholesale and private label

Distributors and importers work through wholesale and private label

  • A series is supplied as a set across the models you stock.
  • Your own brand goes on the seat, and bulk supply is arranged by series.
  • The model and the options go on one table, so a distributor with a mixed fleet orders from one sheet.

Detail on both programs is on OEM and ODM seat manufacturer. Mounting and compatibility data are on seat fitment and compatibility.
