A loaded Caterpillar 740 articulated ejector truck ran out of diesel fuel and shut down ascending a 10% gradient. The truck stopped, then rolled backwards for 49 m when the truck’s service brakes (dynamic brakes)
Understanding the Function of a Drop Box in an Articulated Dump Truck
2023年9月6日 · The drop box is a vital component in the operation of an articulated dump truck, responsible for power distribution and maneuverability. Understanding its function, major components, common failures, and maintenance practices is essential for keeping the truck in optimal working condition.
Service brakes fail on moving articulated dump truck
2022年11月7日 · A loaded Caterpillar 740 articulated ejector truck ran out of diesel fuel and shut down ascending a 10% gradient, only to roll backwards when its service brakes failed. Service braking systems on mobile plant are safety critical systems and their failure during operation has the potential for fatal consequences.
Failure analysis of frame crack on a wide-body mining dump truck
2015年2月1日 · After five to six months in service, cracks tend to appear in the frame of the truck, near the rear seating of the front leaf springs. To identify the cause of these failures and propose an approach for improving the design, a practical method combined with finite element analysis (FEA), as well as static and dynamic testing, was applied.
ADT Safety Features Abound | Construction Equipment
2022年10月12日 · OSHA states that dump trucks followed by semi-trucks and ordinary pickups are responsible for the majority of back over incidents in the past 10 years on the job. Tip over (overturn) of entire truck or the bed of an articulating dump truck. Tip overs can cause serious injury to both the operator or ground personnel. Property damage incidents.
ARTICULATED DUMP TRUCK SUSPENSION SYSTEMS Testing …
Always lower the suspension to the service position before working on the system. 1. Check the oil level. 2. Look for air bubbles in the oil. This is best done by using a clear bottle to obtain an oil sample. Make this inspection immediately after stopping the engine. 3. Remove the filter elements and inspect the particles removed from the oil.
