Our company recently completed 200-hour simulated durability tests on two 2.5-meter crawler-type compost turning machines at our factory. Upon passing the tests, the units were disassembled, loaded into containers, and shipped to Malaysia. The testing aimed to verify equipment reliability under continuous operating conditions and minimize the risk of unexpected on-site breakdowns.
The tests were conducted on the factory’s test platform, with the two units operating alternately to simulate actual compost turning conditions. The crawler drive systems covered a cumulative distance of approximately 42 kilometers; the hydraulic lifting systems performed over 3,000 lifting cycles; the turning drums executed over 2,000 forward/reverse switching operations; and a total of approximately 800 tons of material was simulated for turning. Technicians recorded bearing temperatures, hydraulic system pressures, and crawler tension every two hours. Both units maintained stable bearing temperature rises (within 35°C), hydraulic pressure fluctuations of less than 0.4 MPa, and crawler tension levels that required no mid-test adjustments. Post-test procedures included replacing hydraulic oil filter elements, retightening all critical bolts, and clearing residual material from the crawlers and turning drums.
For shipping, both units were loaded into a single 40-foot open-top container, positioned with their front ends facing forward and rear frames facing each other, leaving sufficient clearance for operation between them. Wooden wedges were placed at the front and rear of the crawlers, the machine bodies were secured to the container floor’s anchor points using ratchet straps, and dunnage bags were inserted along the container walls. Accompanying documentation includes the durability test report, maintenance checklist, and installation drawings. The shipment has now been sealed and is en route to Malaysia.
