The Switch mechanism assembly is the locking and release unit for the overhead cover. It includes a spring‑loaded latch that securely holds the cover closed and a release lever that allows the driver to open it from inside the cab. This assembly is precision‑engineered for smooth operation and is a critical component of the Overhead cover system.
The Inner cover of top window cover is a trim panel that provides a finished interior appearance for the roof opening. It is made from durable plastic and features acoustic padding to reduce wind and road noise. This inner cover attaches to the main plate using the supplied fasteners, completing the Overhead cover assembly’s interior side.
This welded steel plate forms the main structural cover of the roof hatch. It is stamped and formed from heavy‑gauge steel, then welded at the corners for maximum rigidity. The plate provides a solid mounting base for the hinge, switch mechanism, and seal, and is the primary weather barrier of the Overhead cover. Its powder‑coated finish resists corrosion and matches the cab’s exterior colour.
The Plastic split rivet is a self‑retaining fastener used to attach the inner cover to the main plate. Its split design expands upon insertion, providing a secure, vibration‑proof hold. These rivets are easy to install and remove, making them ideal for the Overhead cover where occasional access to the roof area is needed.
The Ejector seal is a flexible rubber component that forms a watertight and dust‑proof barrier between the cover plate and the cab roof opening. Its unique profile also provides a slight spring force that assists in popping the cover open when released. This seal is essential for preventing leaks and maintaining a quiet cab environment, making it a critical part of the Overhead cover.
The Hinge is a heavy‑duty pivot joint that allows the cover to swing open smoothly. It is constructed from galvanised steel with a stainless‑steel pin to resist rust and wear. Two hinges are supplied to support the cover evenly, ensuring a balanced and durable opening mechanism for the Overhead cover.
This combined fastener includes a cross‑recessed pan head screw with a pre‑assembled flat washer. It is used to secure the inner cover and other lightweight trim components. The flat washer distributes the clamping load and prevents damage to the plastic surfaces. These screws are an integral part of the Overhead cover’s assembly.
The gasket is a thin, compressible sealing layer placed between the hinge and the cab roof to prevent water ingress around the mounting points. It also reduces metal‑to‑metal contact, minimising noise and wear. This gasket is an often‑overlooked but essential component of the Overhead cover, contributing to its long‑term weather resistance.
This pre‑assembled fastener consists of a hexagon head bolt, a spring washer, and a flat washer. It is used for the most critical mounting points, such as attaching the hinge and switch mechanism to the cab roof. The spring washer provides a locking action to prevent loosening under vibration, while the flat washer ensures an even clamping force. This assembly is vital for the structural integrity of the Overhead cover.
Our Overhead cover is manufactured to Sinotruk’s original specifications, ensuring a perfect fit on the HOWO 7 cab roof. Every component, from the welded plate to the smallest rivet, is designed to work together flawlessly, providing a factory‑fresh appearance and reliable performance.
The ejector seal and gasket work together to keep water, dust, and noise out of the cab. The steel plate is corrosion‑resistant, and the hinges are built to withstand years of opening and closing. This Overhead cover is designed to last the lifetime of the vehicle.
We supply every screw, bolt, rivet, and washer needed for a full installation of the Overhead cover. No additional parts are required, saving you time and ensuring a professional, hassle‑free repair.
The Overhead cover is designed for straightforward replacement with basic hand tools. The split rivets and pre‑assembled fasteners simplify assembly, and the clear installation guide makes it accessible for both professional workshops and DIY enthusiasts.
The Overhead cover is a functional and aesthetic component of the HOWO 7 dump truck cab, providing access to the roof area for ventilation, emergency exit, or maintenance. Its robust construction and precise sealing ensure that the cab remains dry and quiet, even in the toughest working conditions.
The top window cover plate welding is the backbone of the assembly, formed from high‑strength steel with a precision‑welded seam. Its rigid structure supports the weight of the cover and provides a stable mounting surface for the hinges and latch mechanism. The powder‑coated finish is not only attractive but also protects against rust and stone chips.
The switch mechanism assembly is engineered for reliability, with a chrome‑plated latch and a spring‑loaded release that gives a positive feel. The inner cover, made of impact‑resistant plastic, neatly finishes the interior side and includes a foam seal to further reduce noise transmission. Together, these components make the Overhead cover a pleasure to operate.
The ejector seal is a multi‑functional component: it seals against water and dust, it provides a cushioning effect when the cover is closed, and its slight upward force helps the cover pop up when the latch is released. This clever design eliminates the need for a separate spring mechanism, simplifying the assembly.
The hinges are made from corrosion‑resistant steel with a stainless‑steel pivot pin, ensuring smooth operation even in salty or humid environments. Each hinge is pre‑drilled with the correct hole spacing to match the cab roof and the cover plate, so no extra drilling is needed during installation.
All fasteners are supplied in the correct sizes and quantities. The cross‑recessed pan head screws with flat washers are perfect for securing the inner cover, while the hexagon head bolt assemblies – complete with spring washers – are used for the hinge and latch mounting. The spring washers provide a positive lock that prevents loosening due to road vibration, a common issue in heavy trucks.
The plastic split rivets are a clever choice for attaching the inner cover because they are quick to install and do not require a threaded hole. Their split shank expands when driven into place, creating a permanent, rattle‑free connection. If the inner cover ever needs to be removed for maintenance, the rivets can be drilled out and replaced easily.
The gasket plays a crucial role in sealing the hinge attachment points. Even a small gap can allow water to seep into the cab, causing rust and interior damage. Our Overhead cover kit includes this often‑overlooked component, ensuring that your repair is thorough and lasting.
Replacing the entire Overhead cover is a proactive maintenance step that can prevent water leaks, wind noise, and rattling that often develop with age. Rather than patching a damaged seal or fixing a broken hinge, this kit provides a comprehensive solution that restores the roof hatch to like‑new condition.
Installation is straightforward: remove the old cover, clean the mounting surface, and install the new cover using the supplied hardware. The hinge bolts require torqueing to the specified value to ensure proper alignment and sealing. The entire process can be completed in under an hour with basic tools.
For fleet operators, standardising on this genuine Overhead cover ensures consistent quality and fit across all trucks. The durable materials reduce the need for frequent replacements, lowering total cost of ownership. The weathertight seal also protects the cab interior, reducing the risk of electrical faults caused by moisture.
The ejector seal is moulded from EPDM rubber, which is highly resistant to ozone, UV, and temperature extremes. It retains its flexibility from -40°C to +80°C, ensuring that the Overhead cover remains sealed in all weather conditions.
We recommend that the Overhead cover be inspected annually for signs of seal wear or hinge corrosion. Replacing the entire kit at the first sign of deterioration prevents more serious water damage and interior mould growth.
We back our Overhead cover with a 12‑month warranty against manufacturing defects. Our technical support team is available to assist with any installation or compatibility questions.

Choosing a genuine Overhead cover ensures that your HOWO 7 maintains its original cab integrity and resale value. Aftermarket covers may not have the same sealing profile or material thickness, leading to premature failure and leaks.
The switch mechanism is designed with a safety catch that prevents the cover from opening accidentally while driving. This feature is especially important for dump trucks that operate on rough terrain, where sudden movements could otherwise cause the cover to pop open.
The inner cover is equipped with integrated clips that hold the wiring for the roof lamp (if equipped), keeping it tidy and preventing rattles. This attention to detail is typical of genuine Sinotruk parts.
