Backhoe loader of the backhoe could cause the vehicle to tip, most backhoe loaders use hydraulic outriggers or stabilizers at the rear when digging and lower the loader bucket for additional stability. This means that the bucket must be raised and the outriggers retracted when the vehicle needs to change positions, reducing efficiency. For this reason many companies offer miniature tracked excavators, which sacrifice the loader function and ability to be driven from site to site, for increased digging efficiency. Their relatively small frame and precise control make backhoe-loaders very useful and common in urban engineering projects such as construction and repairs
Rear-eject haul truck bodies The truck can also be driven while dumping is in progress; this reduces subsequent time and effort spent on grading the dumped material. Rear-ejects are typically better suited to completely eject sticky material, preventing "carry-back." A rear-eject truck can deliver a load in an area with a low overhead barrier. Rear-eject haul truck bodies Rear-Eject Haul Truck Bodies are an alternative haul truck body style developed for quarry, road-building, steel mill, landfill and underground mining applications. Instead of lifting the bed vertically, the hydraulic cylinder pushes a ram-face horizontally through the body to eject the hauled load. Rear-eject dump vehicles
