Product Description:

WK series excavators are used for open-pit mines. They have been developed through a combination of years of successful experience in the manufacturing of mining shovels and the adoption of advanced technology in design, processing, and manufacturing from home and abroad. They are suitable both for stripping and excavating open-pit coal mines, iron mines and ferro-metal mines.

Our WK series excavators feature such state-of-the-art technology as three-dimensional imitation and definite circle analysis. They perform well and can be used effectively according to users’ requirements in combination with various haul trucks and crush stations for higher loading and lower production costs.

Our excavators’ electric system uses a rectifier/regeneration communal DC bus-bar and variable frequency speed adjustment system. The electric control, with PLC at its core, is a 3-stage system of up-position monitoring, field bus and frequency variable speed control. It causes not disturbance to the power grid, allowing a wider range of power voltage fluctuation and high power factor. The system is loaded with software to optimize the dig/cut curve and automatically optimize the hoist and dig power distribution. The system automatically troubleshoots, displays status, and calculates electric power. This system has the advantages of state-of-the-art technology, reliable operation, high transmission efficiency and low power consumption. Our WK-75 excavators are designed to be used in combination with mining trucks with a capacity over 363MT, and mobile crusher stations with a capacity over 9000t/h.

Technical characteristics:

• Gear-rack crowding, powerful penetration, highly efficient;

• Gear transmission uses gears of high hardness surface for durability;

• Uses a planet reducer for the swing and propel mechanism;

• Propel has a high hand drive for added durability;

• Air release spring disk brakes.

Q:How to remove / destroy 2 feet high brick fence?
Easiest if you plan to do it yourself is to rent a Bobcat with a bucket and a jackhammer tip. Use the pecker to break everything up and then put the bucket on for cleanup. Make sure you have good ear and eye protection. Works great. Good luck.
Q:Who knows all imported excavator brands?
All kinds of projects are available. Disadvantages: the product quality is lower than the average price, moderate price, moderate quality, and poor after-sale. Low inflation. 20T models, DH215-9 reference price, 80-85W DH225-9 86-91W Hyundai: Korean brand, but it is low-end goods, assembled. (HYUNDAI) advantages: cheaper prices, good parts, cheap. Disadvantages: machines can't even reach the standard of domestic machines, either good or bad. Personal view: imported brands can only buy more than these brands, Keith (CASE), JCB (JCB), Kato (KATO), Terex (TEREX), Bohai Seoul (LIEBHER), Sumitomo (SUMITOMO), Ishikawa Shima (IHI), Kubota (KUBATO), Takeuchi (TAKEUCHI) are not allowed to buy. Low share, customer service service points less, difficult to buy accessories, if you buy, there will always be these problems.
Q:What can I use in place of Zoo Med's Excavator for a leopard gecko?
If you want a clay substitute I don't think there's another kind that is sold specially for reptiles but look up what kind of clay is safe to use for leopard geckos.
Q:explain how to do this math question? PLEASEEE.?
set up an equation: 21.9=2t+t with 21.9 standing for excavator, and t for tractor simplify to get 21.9=3t divide 21.9 by 3 t=7.3 (that's the mass of the tractor) for the excavator, multiply 7.3(2) to get 14.6 tractor=7.3 excavator= 14.6
Q:What is the difference between a Track Hoe (Excavator) and a Back Hoe?
Track Hoe Excavator
Q:hi i was wondering what would be the quickest way to install 200 metres of ranch style fencing?
Have put up a lot of fences... but not necessarily an expert. Good sources on the web in many DIY places... but in my opinion: A lot depends on the type of soil you're putting the posts in, and the climate. Dry climate and rocky soil would be less dependent on adding concrete. Moist climate and/or sandy soil would require something more substantial. And, it also depends on how high the fence is going to be and what you intend to keep in or keep out. In any case, would likely recommend treating the bottom couple of feet of the posts with a tar or creosote before installation to prevent rot and moisture penetration (Regardless of whether you use cement or not.) My experience, in rocky soil and an alpine climate, involved using a post-hole attachment on an International Harvester, a spud bar to break up rocks, and a supply of rocks to tamp back around the post once it was dry set. Six inches of large gravel in the hole. Insert post. Tamp large rocks around post with spud bar. Fill with dirt. Tamp some more. No concrete. Posts that loosen with time can be readily re-set. A slightly improved option, is to set the corner posts and gate posts in concrete and dry set the others. That works pretty well and saves some $$$. If you're going all out: treat the posts, drill the holes, bed with gravel, set the post, fill with concrete, slope the concrete away from the post, use bracing as necessary to maintain plumb. Can do a bunch or a few at a time that way. Make sure to cover the concrete with plastic as it dries to slow the drying and reduce cracking. Good luck. I'm sure there are lots of other good/better ideas as well. One nice option = the poly/vinyl fencing. Less weight. Very durable. Comes with instructions.

Q:excavator clay for leopard gecko?
Oof. Take that crap out, oh lord he might be crying inside from th e noise. Take out the plastic wrap and put paper towel in for substrate, much easier and better for the gecko in general. Or sand if your careful about compaction.
Q:How do you install and plan for plumbing in a building you are going to build?
That's your contractor's responsibility.
