YY53 Forklift Seat Supplier for Forklift Builders and Distributors48 mm Mechanical Suspension for 40 to 120 kg Operators
- 40–120kgoperator weight band
- 48mmmechanical suspension travel
- 70°–115°backrest range
KL Seating supplies YY53 to two groups: forklift builders and truck converters that fit a seat to every truck on the line, and distributors and importers that stock seats for trucks already in service. YY53 is a mechanical suspension seat. Its published sheet gives 48 mm of suspension travel, an operator band of 40 to 120 kg, a backrest that adjusts from 70° to 115° and a seat weight of 18 kg.
No other forklift model on our range publishes all four of those figures together. YY53 carries a PVC cover and lists a seat belt and an electronic lock as options. It is supplied inside our OEM and ODM service, so a change to the option set or the base goes into the same enquiry.
What to send: the truck model, the lightest and heaviest operator weights and the seat belt or electronic lock connection your truck uses, or photos of the seat being replaced. The reply is the YY53 parameter sheet plus a fit statement that flags any mismatch.

Operator Weight Band: 40 to 120 kg for Trucks With Lighter Operators
40 to 120 kg is the lowest published band on the forklift range, shared only with YY03. KL01 and KL11 start at 50 kg and run to 130 kg; YY01 runs from 50 to 120 kg.
A mechanical seat is adjusted to the person sitting on it. The (the range across which that adjustment is made) is the span over which that adjustment works. A truck sold into a market with lighter operators sits at the low end of it, which is where YY53 reaches further down than KL01 or KL11.
The lightest operator is at or above 40 kg.
A builder takes the lightest and the heaviest operator that the truck is sold for and checks that both fall inside 40 to 120 kg. The band is fixed at the specification stage.
The heaviest operator is at or below 120 kg.
A distributor reads the band against the operators of the fleets it supplies. Shared and rental trucks change hands between shifts, so the lightest and the heaviest driver across the fleet both have to fall inside the band.
If the heaviest operator is above 120 kg, the reply points to KL01 or KL11, whose bands run to 130 kg. The method used to set the seat to a given weight is confirmed in the reply with the parameter sheet.
Suspension Travel: 48 mm Read Together With the Weight Band
48mmYY53 has 48 mm of suspension travel. It is one of two forklift models with a published travel figure, the other being KL01 at 50 mm. KL11 and YY03 do not publish a travel figure.
Travel and weight band are read as a pair.
- The band tells you which operators the seat can be set for.
- The travel tells you how much room the cab has to give the seat.
If you hold a cab drawing
A builder who has a cab drawing sends the free height at the seat position along with the operator weights, and the reply compares the 48 mm figure with that height.
If you hold an old seat
A distributor who has an old seat sends photos of the seat from the side, and the reply reads the old seat's travel against 48 mm.
YY53 is the model to ask for when the truck is specified to a travel of 48 mm. A truck specified to 50 mm points to KL01 and a truck that needs a published figure from a different family points to the suspension seats page, which lists the travel of every model across the range.
YY53 uses mechanical suspension. The forklift range has no air bag suspension model, and seats with an air bag are in the agricultural range. The shock absorber of YY53 goes through mechanical analysis in our testing center, described in its own section below.
Backrest Range: 70° to 115° and the Clearance Behind the Seat
YY53 adjusts the backrest across 70° to 115°. Among the six forklift models, only KL01 and YY53 publish a backrest range, and KL01 covers 15° to 130°. YY53 gives the narrower (the angle range on the published parameter sheet) of the two.
Forklift builders
A builder compares the range with the clearance behind the seat in the cab. The distance from the seat back to the nearest panel, guard or counterweight side is measured and sent with the enquiry.
Distributors and importers
A distributor reads the same item from the old seat: a photo of the old backrest from the side shows the angle the truck was working to, and the reply compares it with 70° to 115°.

| Angle the truck needs | YY53 window, 70° to 115° | KL01 window, 15° to 130° |
|---|---|---|
| Below 70° but not below 15° | Below the window | Inside the window |

| Above 115° but not above 130° | Above the window | Inside the window |
| Below 15° or above 130° | Outside the window | Outside the window |
Put the angle on the enquiry
The reply compares the angle your truck needs with the 70° to 115° window.
A wider range
KL01 is the forklift model that covers 15° to 130°. The other four forklift models do not publish a backrest range, and the reply confirms it for each if you ask.
Seat Weight: What 18 kg Means for Assembly, Handling and Freight Planning
YY53 weighs 18 kg, and it is the forklift model whose weight is on the published sheet. The figure matters on the buyer's side in three places.
On the assembly line
A builder that fits a seat to every truck uses the weight when it sets up the seat fitting station and the handling aids.
In the warehouse
A distributor stocking seats for replacement work uses the weight for shelving and for the handling of seats in and out of stock.
In freight planning
The weight is one input to the freight plan that purchasing prepares on its own side. Carton size for YY53 is not on the published sheet.
YY53 is the forklift model to pick when the weight figure has to be on paper before the order is placed.
Cover and Options: PVC, Seat Belt and Electronic Lock
YY53 is listed with a PVC cover. Two options are on the sheet.
Seat belt
Belt option listed on the YY53 sheet.
Electronic lock
Option on the seat that connects to the truck.
Photos show the sample seat; the option set is listed in the table.
| Option | Role on the truck |
|---|---|
| Seat belt | Belt option listed on the YY53 sheet |
| Electronic lock | Option on the seat that connects to the truck |
Not listed for YY53:
- Armrests
- Headrests
- A micro switch
- Slide rails
- Fabric
A truck that needs one of them moves to the model that lists it. KL01 lists armrests, headrests, seat belts, an electronic lock and slide rails, with PVC or fabric. KL11 lists a seat belt, a micro switch and slide rails. The forklift seat manufacturer page shows the option list of all six models side by side.
Electronic Lock Option: Connection Details to Confirm With the Factory
The electronic lock is the option that needs information from the truck. It is one of the two options listed for YY53. The sheet names the option. It does not carry the lock's interface, its wiring or its supply, so those items are confirmed by the factory before the option is accepted on an order.
YY53, 40 to 120 kg, seat belt and electronic lock, connection per attached photo
- The truck make and model.The reply is written against that truck.
- What the truck expects from a seat lock.In the words of your own specification.
- The connector or wiring your truck uses at the seat position.As a photo or a drawing page.
- Whether the old seat on the truck carries a lock.With photos of the lock and its wiring.
The reply states what the factory can supply for YY53 against that information, and it names anything that does not match. We do not assume a connection. A line such as the one opposite is enough for the first reply to carry a single configuration.
KL01 also lists an electronic lock, and YY01 lists one. If the truck's lock connection fits one of them better, the reply says so.
Items Not on the YY53 Sheet: Confirmed by the Factory on Enquiry
The published YY53 sheet carries weight band, suspension travel, backrest range, seat weight, cover and options. It does not carry the items below. Each one comes from the factory against the model number, and a value that is not on file is stated as such in the reply.
| Item | How it is handled |
|---|---|
| Fore-aft slide | Not published, ask the factory |
| Slide rails | Not listed, ask the factory |
| Overall dimensions | Not published, ask the factory |
| Mounting-hole spacing | Not published, ask the factory |
| Carton size | Not published, ask the factory |
We do not fill any of these from KL01, KL11 or another model. Purchasing places the order against the sheet that comes back, and the engineer compares each value with the cab drawing or the old seat before anything is ordered.

| Cover | PVC | PVC or fabric | Black PVC |
| Options | Seat belt, electronic lock | Armrests, headrests, seat belt, electronic lock, slide rails | Seat belt, micro switch, slide rails |
Choose YY53
When the operators include anyone between 40 and 50 kg, when the truck is specified to a 48 mm travel, or when the seat weight and a backrest range of 70° to 115° have to be on the sheet.
Choose KL01
When the truck needs operators up to 130 kg, a 50 mm travel, a backrest from 15° to 130°, fabric, armrests or headrests.
Choose KL11
When the truck needs a published fore-aft slide of 176 mm or a micro switch.
The travel gap between YY53 and KL01 is 2 mm, so the choice between them rests on the weight band, the backrest and the options.
YY53 Production Route: Foam Molding, Precision Stamping, Robotic Welding and Assembly
Four steps, in this order.
- STEP 1
Foam molding
Cushion and backrest are formed on the foam molding line.
- STEP 2
Precision stamping
An automated precision stamping line forms the frame and the base.
- STEP 3
Robotic welding
A robotic welding station joins the frame.
- STEP 4
Assembly
The suspension and the chosen options go on at assembly.
- MES runs across R&D, purchasing, production, quality inspection, warehousing and delivery, and YY53 sits on the same chain as the rest of the forklift line.
- CAE structural analysis at the design stage examines how the frame carries load before any part is formed.
- Pressure distribution comfort testing on the cushion shows how load spreads across the seat surface while sitting.
Seats since 2007; KL Seating brand since 2016.
Shock Absorber Mechanical Analysis: The Inspection Item That Applies to YY53
Every mechanical suspension seat on the forklift range (YY53, KL01 and KL11) has its shock absorber put through mechanical analysis in the testing center. What it measures is the force behavior of the shock absorber as a component, apart from the seat around it.
The result confirms that travel and weight band on YY53 work together. Shock absorber analysis is one item on the testing center list.
The analysis stops at the shock absorber. Cab checks stay with the engineer:
- The free height at the seat position
- The clearance behind the backrest
- The connection of the electronic lock
We publish no inspection pass values or sampling ratios for YY53; the documents a buyer can request are in the certificates section below.
Mounting Base: 3D Scan Check and Hole Pattern Request
The base is the part of YY53 that meets the truck floor.
Stamp
The base comes off the automated precision stamping line.
Weld
Stamped parts are joined at the robotic welding station.
3D scan
A scan logs the bottom hole positions and the outer frame dimensions and checks them against the design data.
Parameter sheet
What the scan logs is returned to you as the model's parameter sheet.
Hole pattern request
YY53's mounting-hole spacing is not on the published sheet. Send the hole pattern of the truck floor plate or of the old seat base and the reply sets it against the YY53 base. A truck that needs another pattern goes to the R&D center on the ODM route, and the modified base follows the same stamping and welding steps.
Supply Routes: OEM and ODM for Builders, Private Label for Distributors
YY53 enters through the OEM and ODM service, one of the ways the company supplies seats.
Builders and truck converters
Send the truck drawing marked with the seat position, along with the operator weight range and the options you want.
If the structure has to change, the R&D center takes it up on the ODM route.
Distributors and importers
Photos of the seat on the truck, or just the truck model, are enough to get the YY53 match back.
For your own brand or a bulk supply range, say so in the enquiry; model and options stay on the same line.
How the whole process runs is on the OEM and ODM seat manufacturer page.
