Let's cut to the chase—landfill space is expensive, and wasting it costs you serious money. As a professional backhoe loader manufacturer with 20 years of heavy equipment experience, we know what it takes to build machines that survive the worst conditions. Based in Taian, Shandong—China's construction machinery capital—we have direct access to over 300 local suppliers of premium heavy equipment components. This means we can build tougher compactors at a genuine factory price that no middleman can match. Every weld, every drum tooth, every hydraulic part is built to last.
After two decades of Chinese construction machinery export, we've shipped hundreds of compactors to over 30 countries. We know exactly what international customers need: reliable performance, easy maintenance, and affordable shipping. Our engineers perfected the 40HQ container loading plan to fit 1 complete ZT821 unit per container with all standard accessories. Our export team handles everything from customs paperwork to door-to-door delivery, so you don't have to deal with the headaches of international logistics.
Ordinary construction machines fall apart in landfills, but the ZT821 is built specifically for this brutal environment. It operates 24/7 through corrosive gases, abrasive waste, and uneven terrain. The 900mm wide steel drums with 64 sharp teeth penetrate deep into waste layers, achieving a maximum density of 1000kg/m³. The 3350mm wide pushing shovel spreads waste efficiently, while the 280mm ground clearance prevents bottoming out on rough surfaces. We also offer Euro 5/EPA compliant engines for European and American markets.
Quality isn't optional when your machine runs 24 hours a day. Every ZT821 goes through a brutal 12-step quality control process, from raw material inspection to final testing. We only use certified heavy equipment components from trusted suppliers, and our factory is ISO 9001:2015 certified. Before any compactor leaves our facility, it runs non-stop for 72 hours under full load. If it can survive our testing, it can survive anything your landfill throws at it.
Downtime in a landfill is not an option—it backs up your entire operation. That's why we offer more than just a great factory price. Our global after-sales team provides 24/7 online support, so you can get help at any hour. We stock thousands of spare parts in our Taian factory and have warehouses in key overseas regions for fast delivery. We even provide free operator training to make sure your team gets the most out of your compactor.
The ZT821 doesn't just compact waste—it saves you money in every way possible. Higher density means you get 30% more use out of your existing landfill space. The fuel-efficient Weichai engine cuts operating costs by up to 20%. And our durable design means less maintenance and longer service life. As a trusted backhoe loader manufacturer and waste equipment supplier, we stand behind every machine we build with a comprehensive 1-year warranty.
