1. The mine must use machinery. Without machinery, can it be moved by manpower
as for which excavator or loader is used more, go and investigate the mine by yourself! Excavator is mainly digging, loader is mainly loading.
2. Anhui hekuang is not bad. Many people say that they have been on the computer for a long time, and they can work alone after two or three months of internship after graation. What a cow! How fast
3. Generally speaking, 80 machine is 8 tons, 100 machine is 10 tons, like Komatsu brand machine, Komatsu 120 is 12 tons, of course, there are special features.
4. Look at this post. http://bbs.cehome.com/thread-204552-1-1.html Is mine excavator driver hair, under the reference

Walking and braking mechanism driven by hydraulic motor, full hydraulic walking mechanism deceleration mechanism differential planetary gear deceleration maximum traction 229kn high walking speed 0-4.4km/h low walking speed 0-2.67km/h walking braking hydraulic locking parking braking hydraulic disc brake 3 Hydraulic system type full power regulation, negative flow control hydraulic pump type double plunger variable displacement pump + gear pump purpose walking mechanism, slewing mechanism, working device maximum flow 2 × 264l / min hydraulic motor type plunger motor purpose maximum working pressure of traveling mechanism and slewing mechanism system 31.4mpa (320kg / cm2) maximum working pressure of slewing mechanism 24.5mpa (250kg / cm2) working pressure of pilot control system 3.9Mpa (40kg / cm2) number of hydraulic cylinders cylinder diameter x stroke boom cylinder 2-140mm × 1480mm bucket cylinder 1-160MM × 1685mm bucket cylinder 1-140mm × 1285mm stick digging force 130kN, bucket digging force 170kn4, slewing mechanism driving mode hydraulic motor driving slewing rection mechanism planetary gear drive slewing locking hydraulic disc brake slewing speed 9.72r/min, slewing bearing lubrication mode regularly coated with grease 5, crawler frame reinforced X-frame crawler st ring sealed tension buffer mechanism hydraulic tension, spring buffer crawler plate quantity 2 × 47 number of carrier sprockets 2 × Number of 2 rollers 2 × 76. Working range: the maximum excavation radius is 10920 mm, the maximum excavation depth is 7380 mm, the maximum excavation height is 10210 mm, the vertical excavation depth is 6480 mm, the maximum unloading height is 7180 mm, the minimum rotation radius is 4260 mm. Parts: Japanese walking motor, three-stage air filtration system, Japanese original main pump, new type full electric power selection system, Japanese original rotary motor, Japanese original main valve. These are the main ones. For the assembly of large machinery, there are more kinds of small parts. Some are attached to large parts, some are customized, and some are purchased in the general market. It's also a part of business secrets. How can we talk about it casually.
