The work platform is an essential accessory that provides safe, non slip access to the chassis and the rear of the cab. A sturdy work platform allows drivers and mechanics to stand securely while connecting air lines, checking lights, or performing minor maintenance. This genuine HOWO work platform kit includes the walking board plate, the fixing clips, and the M8 flange bolts. When you choose authentic Howo Parts, you receive a complete work platform assembly engineered specifically for the MAX 4X2 chassis side rail.
The walking board plate fixing clip is a galvanized steel bracket that attaches the walking board to the chassis frame. Four clips are supplied, each with a pre formed shape that matches the contour of the chassis rail. The clips are designed to hold the board securely without rattling while allowing slight thermal expansion. A rubber pad on the inner surface of each clip prevents metal to metal contact and reduces noise.
The walking board plate is the main platform surface made from heavy duty expanded metal with a non slip pattern. The plate measures approximately 800mm by 250mm and is stiffened with a folded edge and integral ribs. It provides a stable, slip resistant standing area for accessing the fifth wheel area and the rear chassis components. The plate is coated with black powder paint that resists rust and abrasion, and the open mesh design allows mud and water to fall through rather than pooling on the surface.
The hexagon bolt with flange M8 is a zinc plated, class 8.8 fastener used to secure the fixing clips to the chassis and the walking board to the clips. Four bolts are supplied, each with an integrated flange that distributes clamping pressure and eliminates the need for a separate washer. The M8 thread is the standard size for chassis mounting, and the bolts are pre coated with a thread locking compound to prevent loosening under vibration.

The walking board plate is made from 3mm thick expanded steel with a diamond pattern that provides excellent slip resistance even when wet, icy or covered in mud. The open mesh design prevents the accumulation of dirt and water, keeping the platform clean and safe.
The combination of the contoured fixing clips and the M8 flange bolts holds the work platform tightly against the chassis rail. Rubber isolators on the clips dampen vibration and eliminate the rattling that is common with cheaper, generic steps.
All components are protected against rust. The walking board plate has a black powder coat finish, the fixing clips are galvanized, and the bolts are zinc plated with a thread locking compound. This ensures the work platform remains serviceable for years even in humid or salty environments.
This work platform kit includes exactly the right number of clips, the correctly sized plate, and the four M8 flange bolts. No additional drilling or hardware is required. The assembly bolts directly to the existing holes in the HOWO MAX 4X2 chassis side rail.
The walking board plate is pressed from a single sheet of expanded steel, which is then folded to create a stiffening channel along the long edges. The diamond shaped openings are approximately 10mm by 20mm, large enough to allow debris to fall through but small enough to provide secure footing. The plate is then cleaned and powder coated in black with a textured finish that adds additional slip resistance.
The fixing clips are laser cut from 4mm thick steel plate, then bent to a precise 90 degree angle with a curved inner face that matches the radius of the chassis rail. Each clip is galvanized in a hot dip process that provides a thick, durable coating. The hexagon bolts with flange M8 are class 8.8 and include a pre applied nylon patch that acts as a thread locker, preventing the bolts from backing out under vibration.
Before starting, clean the chassis side rail area where the work platform will be mounted. Position the walking board plate against the chassis rail, aligning the mounting holes with the existing threaded holes in the rail. Place one walking board plate fixing clip over the plate from the outside, and another clip from the inside of the rail.
Insert one hexagon bolt with flange M8 through the clip and plate, and thread it into the chassis hole. Repeat for the remaining three mounting points.
Tighten all bolts to 25 Nm using a 13mm socket. Do not overtighten, as this could distort the clips or crack the powder coat on the plate. After installation, test the platform by stepping on it and bouncing gently; there should be no movement or noise. The platform is now ready for use.
This work platform is designed specifically for the HOWO MAX 4X2 chassis with the standard frame rail spacing. It is compatible with both day cab and sleeper cab versions, as the mounting holes are in the same location on all MAX 4X2 trucks.
It is not compatible with the older HOWO 70 series or with 6X4 and 8X4 chassis, as those have different frame rail widths and hole patterns. If your vehicle has been modified with aftermarket fuel tanks or exhaust aftertreatment devices that block the side area, please verify clearances before ordering.
Inspect the work platform every 50,000 km. Check for any loose bolts; retorque the M8 flange bolts to 25 Nm if needed. Look for cracks in the walking board plate or the fixing clips, especially around the weld lines. If the powder coating is scratched, touch up with a rust inhibiting paint to prevent corrosion. Clean the platform regularly with a pressure washer to remove mud and road salt that could accelerate wear. The rubber isolators on the clips can be replaced if they become hard or cracked.
Climbing onto the chassis rail without a proper step is dangerous, especially in wet or icy conditions. The work platform provides a stable, non slip surface that reduces the risk of slips and falls. It also protects the chassis rail paint from being scraped off by boots, which could lead to rust.
For drivers who need to connect and disconnect air lines or electrical cables for trailers, the platform provides a safe place to stand at the correct height. Insurance records show that many workplace injuries occur when climbing onto truck chassis; a proper platform eliminates this hazard.
Aftermarket work platforms often use thinner expanded metal that bends under the weight of a person. The fixing clips may be made from soft steel that bends during installation, causing the platform to be loose. Generic bolts may not have the thread locking patch, so they can vibrate out over time, leaving the platform attached by only one or two bolts. Genuine HOWO work platform components are made from the correct thickness materials, the clips are heat treated for strength, and the bolts include the nylon locking patch. The small additional cost of genuine parts ensures that the platform remains safe and secure for the life of the vehicle.
The work platform components are manufactured in an ISO 14001 certified facility. The steel is sourced from mills with recycled content. The powder coating is free of heavy metals. The packaging consists of a cardboard box with foam padding to prevent scratching of the powder coat. All packaging materials are recyclable.
The complete work platform kit can be ordered using the master assembly number YG952593003010 (walking board plate) together with the clips and bolts. Individual components are available using the material encodings in the parameters table. Authorized HOWO dealers in Nigeria stock these genuine parts. For fleet orders of ten or more kits, volume discounts are available. Always provide your vehicle’s VIN to confirm the presence of the correct mounting holes on your chassis.
Fleet managers who have installed this genuine HOWO work platform report that their drivers and maintenance staff are much safer when accessing the rear of the cab. The non slip surface works well even during the rainy season. The platform does not rattle or loosen over time, a common complaint with generic steps. The powder coat finish has held up well against the abrasive dust on laterite roads. Many operators have standardized on this work platform for all new vehicles.
The work platform is shipped in a sturdy cardboard box measuring 85cm x 30cm x 10cm, weight 8 kg. The walking board plate is wrapped in protective foam. The clips and bolts are in a sealed poly bag. Store the kit in a dry indoor area. Avoid stacking heavy items on top of the box to prevent bending the plate. The shelf life is indefinite when stored properly.
