- Q: Working principle of excavator running motor
- Excavator motor principle: the large crawler excavator machine weight is generally above 20t, machine inertia, in the process of starting and stopping of the machine will bring bigger impact to the hydraulic system, therefore, must improve the walking control system to adapt to this condition.The motor generally adopts high speed motor plus planetary reducer or cycloidal pin gear reducer, while the control of the loop of the hydraulic motor has its characteristics. Walking motor control loop shown in Figure 1, the motor is equipped with a high-pressure automatic variable device, when hung high gear when the circuit is connected with the manual transmission oil to oil, promote the transmission valve moves to the left, the motor for small displacement; if the driving resistance increases the pressure rises to the set value, the oil valve drive transmission right for large displacement, low gear automatic variable motor, to increase the torque. Therefore, the motor can automatically change gears as the walking resistance changes.

- Q: What about sunward excavator?
- The first to buy 31, service pissed me off, the vehicle and expensive, I bought 4 sets of mountains and rivers, there are agricultural, high price, Shanxi side of the service is good, what did not urge repayment so anxious, but also some small problems is acceptable, the service is also very timely. After all, the price in a car, a kind of 10 plus the quality certainly with tens of thousands of imported cars, hit number a price why spend the money, as long as the service to keep up, sunward is a very good choice
- Q: I don't want to dig the entire area (15-18 foot circle) with just a shovel. I can't afford a bobcat, so will a tiller or something like that be good to rent for the day from an equipment rental place? My yard slopes some, so I have to dig up a couple of feet on one side to make it level.
- It would be best and economical to rent a bobcat for a day for about 400-450.00 a day and level off your land to insure that the pool would be level. Or contact your local Landscaper and Design Team and they ususally will have a bobcat ..But they Will CHarge Outrageously. Or Why wont you let the pool people do it for you..They probably will have to contract out..But it will be done professionaly. Unfortunately There are some things that We as Homeowners Must never try to tackle. good luck =}
