WL8-8442 PP Wheeled Protective Case

Both share the same 740*518 mm internal floor. The 8434 gives 284 mm internal depth, measures 843*592*335 mm outside and weighs 14030 g, while the 8442 gives 364 mm, measures 843*592*415 mm and weighs 15320 g. The 8442 has the deepest cavity and the heaviest empty weight in this group, which suits upright equipment and multi layer fixtures; choose the 8434 when flat items will do.

It takes large upright instruments, precision gear located by three foam layers, and fixtures or tool groups stored by process step. Load heavy parts into the lower layer near the middle on the wheel side, separate layers with thin foam and press a thin pad on top. If the total height approaches 364 mm, send a drawing first so we can confirm access clearance.

The polypropylene shell is injection moulded with a sealing structure and the closed case is rated IP67 for water and dust protection, covering rain, dust and short immersion. We do not claim military standard certification for this model. A deep, wide body runs a long sealing path, so check the gasket regularly, clear the sealing face and close the latches evenly to keep the seal effective.

At 15320 g empty this is the heaviest model in the group. Once loaded, roll it only on firm level ground using the handle and wheels; the 295 mm handle sits low. On stairs, when loading a vehicle and over steps or uneven ground, lift with two or more people, support the base and never let one side carry the load or drag the case.

Yes. Kexin New Materials (Guangdong) Co., Ltd. supplies factory-direct from its Zhongshan factory under OEM and ODM programmes, so foam inserts, colour, silk-screen printing, nameplates and latch options can be adjusted. A 364 mm depth suits multi layer construction; send the equipment list, sizes and packing order and we will design the layers for the 740*518*364 mm cavity. Samples ship before mass production begins.
