Face shovel bucket 7495 HF

for draglines

Featuring an entirely new, patent pending design, a new Cat® dipper improves performance and reliability in hard digging applications of the Canadian Oil Sands without increasing demands on the hoist and crowd capabilities of the Cat 7495 HF Electric Rope Shovel. Improvements to shimming and inserts alone are projected to increase uptime as much as 0.25%, potentially leading to significant gains in production. The new design optimizes lip cutting angle, resulting in significantly reduced heel wear. Improving stiffness and dig performance, the ground engagement tools are pitched at an upward angle that results in less bending force and even tooth wear top to bottom. Approximately 7% lighter than the current 45.9 m3 (60 yd3) latched dipper, the new design delivers more available cutting force for more consistent fill factors and increased production in difficult digging conditions. Using Finite Element Analysis (FEA) and virtual validation tools, engineers reduced the dipper’s weight, translating to lower stress on the machine, as well as longer life and improved reliability for key components of the shovel’s front end. The dipper features a new vertical latch system that delivers improved system performance and lower part maintenance, reducing overall operating costs. Rather than sliding, the latch’s tapered-end design lifts the insert surfaces away from each other. The design extends wear life while reducing service time, contributing to improved uptime. The latchbar guide plate features a quick-change design, further reducing maintenance time and costs.
