The excavation action characteristic of a forward shovel excavator is "forward and upward, forced soil cutting"; while the characteristic of a backhoe shovel is "backward and downward, forced soil cutting". The specific details are as follows: 1. Different applicable conditions: The forward shovel excavator can excavate soil above the parking surface, and is suitable for dry foundation pits with an excavation height greater than 2m, but it is necessary to set up ramps. The backhoe excavator can excavate type I to III soils below the parking surface, and is suitable for foundation pits, foundation trenches, and pipe trenches with a depth not exceeding 6m. It is also suitable for wet soil, soil with high moisture content, soil below the groundwater level, and soil in areas with high groundwater levels. 2. Different bucket sizes: The bucket of a forward shovel excavator is larger than that of a backhoe excavator of the same equivalent. Due to the arrangement and connection structure characteristics of the boom and stick, this type of forward shovel excavator is not suitable for excavating working surfaces below the parking surface, but is suitable for excavating working surfaces above the parking surface. 3. It has sufficient lifting force and pushing force, and performs forced pushing motion, making it suitable for all types of soil.

What is the fuel consumption of a manual Sagitar?

The combined fuel consumption of the manual Sagitar is 5.5L/100km. The above is the NEDC combined fuel consumption, which is the fuel consumption data measured under the NEDC test procedure. The actual fuel consumption is higher than this value, around 6.5L. Specific factors affecting car fuel consumption are as follows: Car weight: The larger and heavier the car, the higher the fuel consumption. Generally, a small family car with a 1.6L engine and a weight of about 1.2 tons has a fuel consumption of around 7.5 liters (calculated under full load conditions), while an SUV model weighing about 1.5 tons has a fuel consumption of 8.5 liters. Different weights result in different fuel consumption levels. Drag coefficient: The higher the drag coefficient, the more fuel the car consumes while driving. If the car has a good aerodynamic design, the drag coefficient is lower, leading to lower fuel consumption. Economical RPM: The engine has a most economical torque output point during driving. As long as the car's speed remains within this torque output range, fuel consumption can be significantly reduced. Generally, small-displacement cars reach this point at around 70 km/h, while larger-displacement cars achieve it at about 100 km/h. Maintaining this economical RPM range ensures minimal fuel consumption. Driving style: Aggressive driving behaviors such as sudden acceleration, frequent overtaking, and not easing off the throttle before encountering a red light can increase fuel consumption.

What are the symptoms of a failed engine mount in a BMW 5 Series?

When reversing or starting the car, you may feel engine vibration; the engine shakes noticeably when the car is cold, but the situation improves after the engine warms up. Vehicle vibration: The driver may feel engine vibration when reversing or starting the car; the engine shakes noticeably when the car is cold, but the situation improves after the engine warms up. Steering wheel vibration: The driver can feel vibrations in both the steering wheel and brake pedal when the engine is idling. Abnormal noises: When driving over speed bumps, the driver may hear a "thud" sound from the engine. The engine mount is a rubber block used to secure the engine to the frame. Since the engine produces vibrations during operation, the engine mount helps prevent resonance between the engine and the frame, providing a buffering and damping effect to ensure comfort for the driver and passengers.

What is the difference between the BMW 325 short wheelbase and long wheelbase?

The main difference is that the short wheelbase version has a wheelbase of 2851mm, while the long wheelbase version has a wheelbase of 2961mm. The long wheelbase offers slightly more space compared to the short wheelbase. Introduction to wheelbase: Wheelbase is the horizontal distance between the centerlines of the axles of a locomotive or vehicle. It can be divided into: fixed wheelbase, bogie wheelbase, and total wheelbase. Fixed wheelbase refers to the horizontal distance between the centerlines of the front and rear axles within the main frame of a frame-type locomotive. Wheelbase should not be too long: To facilitate passage through curves, the fixed wheelbase should not be too long. Bogie wheelbase refers to the distance between the centerlines of the axles at both ends of a bogie. Total wheelbase refers to the horizontal distance between the centerlines of the front and rear axles of a locomotive; fixed wheelbase, on the other hand, is the distance from the foremost axle to the rearmost axle that remains parallel during train operation. If the fixed wheelbase is too long, it increases pressure on the tracks during turns and may even lead to derailment.

Why is the boost still insufficient after replacing the turbo on the Haval H6?

There are several possible reasons for low boost pressure in the H6, including exhaust pipe blockage, faulty wastegate valve, air leaks in the piping, or a damaged turbocharger. How turbocharging works: A turbocharged engine relies on a turbocharger to increase the engine's air intake. The turbocharger (Turbo) is essentially an air compressor. It uses the exhaust gases from the engine as power to drive the turbine in the turbine housing (located in the exhaust passage), which in turn drives the coaxial impeller (located in the intake passage). The impeller compresses fresh air delivered from the air filter pipe and sends it into the cylinders. As the engine speed increases, the exhaust gas flow rate and turbine speed also increase, thereby enhancing the air compression level. This results in a corresponding increase in the engine's air intake, which boosts the engine's output power. The function of turbocharging: The primary role of turbocharging is to increase the engine's air intake, thereby enhancing the engine's power and torque, making the vehicle more powerful.

What is the length of the 2020 Geely Boyue Pro?

Geely Boyue PRO dimensions are 4544x1831x1713mm (length x width x height). Measurement method: Vehicle length is the distance between the two extreme points along the length of the car, measured from the most protruding point of the front bumper to the most protruding point of the rear bumper. Vehicle width is the distance between the two extreme points along the width of the car, i.e., the distance between the leftmost and rightmost protruding points. According to industry standards, vehicle width does not include the width of the extended side mirrors (folded mirror width). Vehicle height is measured from the ground to the highest point of the car, excluding the length of roof antennas. Related vehicle dimensions: The dimensions of the standard Boyue are 4519*1831*1694mm, while the Boyue Pro is slightly larger, taller, and has a more imposing appearance.

What is the horsepower of the BMW 525?

525i/Lii is equipped with a high and low power tuned 2.0T engine, with a maximum power of 184 horsepower. Introduction to horsepower: Horsepower is equivalent to the power of a car. The greater the horsepower, the higher the maximum speed. The significance of horsepower lies in the extreme speed performance of the car. The greater the horsepower, the higher the engine speed and the stronger the acceleration. That is, the greater the horsepower, the higher the maximum speed, which is the top speed. Calculation of horsepower: Horsepower is the unit name for calculating metric horsepower. 1 horsepower is the work done in 1 second to complete 75 kilogram-force/meter. 1 metric horsepower = 75 kilogram-force/meter = 735.49875 watts (1Ps=735.49875w).
