The body of the truck is 7.92m in height and 14.63m in length. The gross operating weight of the vehicle is 660t. Terex MT 6300AC became a part of Caterpillar ’s Unit Rig line after Caterpillar ’s acquisition of Bucyrus in 2011. The vehicle was rebranded as Bucyrus MT6300AC, following the acquisition of the mining equipment division of Terex by Bucyrus in 2010. Terex MT 6300AC, introduced by the American manufacturer Terex in 2008, is also an ultra-class mining dump truck with a payload capacity of 400t. It uses GE dual insulated-gate bipolar transistor IGBT) AC electric drive system and can run at speeds of up to 61km/h. The vehicle is powered by a four-cycle diesel-fired 3,500HP Komatsu SSDA18V170 engine with 18 V-type cylinders. The gross operating weight of the truck is 625t while its loading height and the width are 7.09m and 10.01m, respectively. Fitted with big bucket shovels with a capacity of up to 76m 3, the Komatsu 980E-4 is suitable for large-scale mining operations. It is the biggest electric drive rear dump truck from Komatsu.

Non-Metallic Mineral Mining and QuarryingĬaterpillar 797F, the latest model of 797 class dump trucks manufactured and developed by Caterpillar, is the second-biggest mining dump truck in the world.Be aware of how much weight is in the dump box and operate the machinery accordingly. Always wear a seatbelt when operating a dump truck Dumping on Uneven Groundĭumping on an up or down terrain grade can impact the center of gravity and weight distribution in an articulated dump truck, causing it to tip.
Be aware of weather conditions and check steps for snow, ice or mud that could make steps slippery. Three limbs – either two hands and one foot or two feet and one hand – should be on the equipment at all times when climbing ladders or getting in and out of a truck. Use the three-point contact method whenever climbing in or out of a truck. Slips, Trips and Falls While Climbing Into and Out Of a Truck Use audio and visual signals to indicate a reversing truck and avoid taking corners at high speeds. Check all blind spots and utilize spotters when reversing. Backover Incidents Involving People or Other Equipmentĭump trucks are big and heavy equipment that can have many blind spots and lower visibility than other machines.
