The Roll Slope Access is an aluminum ramp that can be rolled up for storage and transportation. When transporting heavy tools and equipment to construction sites or event venues, dollies are often used. There are many sites and venues with various steps, grooves, and obstacles that prevent dollies from reaching the desired location. By simply placing the ramp over the steps, grooves, and obstacles that hinder dolly passage, smooth transit is made possible, eliminating the hassle of manually unloading and transporting all items. It can support weights of up to 500 kg. With a width of 762 mm, it provides ample space for standard dollies to pass through. Its most notable feature is that it can be rolled up. Although the ramp is 1965 mm long (there is also a 1370 mm type), rolling it up allows for compact storage and transportation. Additionally, it comes with a fabric storage bag, making it easy to carry over the shoulder. The ability to use it to bridge over obstacles like curbs is another feature not commonly found in standard ramps. *For more details, please refer to the catalog or feel free to contact us.*

The reinforced plastic sheet UltraX is a genuine sheet that achieves ultra-hardness. It has minimal deformation even on soft ground, allowing vehicles to pass without obstruction. The anti-slip feature is three-dimensional, supporting at points to prevent tire slippage, gripping the ground to keep the sheet in place, while its oval shape, similar to tactile paving, makes it easy for people to walk on, providing multiple functions. The reinforced plastic sheet UltraX uses "high-density polyethylene." Its molecular weight is extremely high compared to regular polyethylene, resulting in a high-quality sheet. Additionally, it uses virgin material instead of recycled material, ensuring uniform quality.

The era of choosing plastic sheets based on performance has arrived. In a time when being lightweight is a given, it is important to discern between the various plastic sheets, identifying those that allow vehicles to run stably and those that are less likely to slip. The reinforced plastic sheet "Koujiban" achieves a "super hard" authentic sheet. With a soft sheet, vehicles may not be able to run stably, and the sheet may become prone to slipping. Therefore, it is crucial for the sheet to be hard, but manufacturing a hard sheet is not easy. "Koujiban" has achieved "super hardness." *For more details about the product, please refer to the leaflet.
