Faqs

During the winter, all vehicle lubricants – whether engine oil, transmission oil, differential oil, hydraulic oil or grease – should be considered. Before starting equipment in extremely cold temperatures, an operator should make sure the oils in the engine, transmission and hydraulic system are fluid enough to flow. Check the engine oils using the dipstick where applicable; other fluids should also be checked by their appropriate methods.

Most dozers use tracks. These models are often also called crawler dozers. They can navigate unstable terrain, such as gravel and refuse piles. Tracked dozers are the most common option.

But there are also some dozers that use wheels instead of tracks. These models are simply called wheel-based dozers. They use heavy-duty tires and hydraulic steering, which leads to impressive agility and tight turning radiuses. These dozers are best for projects that need exact positioning and are often used by facility maintenance crews and sports arenas. They also offer higher horsepower, which is great for the most challenging projects. But keep in mind that they can't offer the same level of traction that a tracked dozer can.

Many dozers are intentionally designed for easy upgrading. They are compatible with attachments, which get connected to the dozer. These attachments help improve the efficiency and/or versatility of the dozer.

One common upgrade is a ripper, which is a claw designed to break through tough surfaces. It's often used on concrete or frozen ground. There are many different bulldozer attachment options available and you can find ones that best suit your given projects.

Yes, a bulldozer can get stuck. Because bulldozers are fitted with tracks instead of tires, they distribute their weight more evenly and are better for working on soft ground. However this does not mean that bulldozers cannot get stuck in soft ground or mud. It can happen and dozers can be difficult to get out once they are stuck. 

There are six steps that can be taken to prevent a dozer from getting stuck:

1) Always examine the worksite plans before starting a project. Be aware of drainage ditches, cisterns, or other holes and caverns. A bulldozer could fall into these and get stuck.

2) Walk the site before bringing out any heavy equipment. There may be debris or other hazards that are not noted on a site map that could pose a danger to a bulldozer or any other equipment types

3) Look for hidden sinkholes, really wet spots or big patches of water. Pay special attention to low and uneven ground.

4) Poke the ground. If a stake can easily be pushed into the ground by hand then a bulldozer will most likely sink.

5) Get a bulldozer that matches the size of a job. Smaller bulldozers may be cheaper to rent and to fuel and are easier to remove if they get stuck. Do not opt for a giant bulldozer if it is not needed for the job.

6) If it does not feel safe to use a dozer, refrain from doing and wait until the site conditions improve. 

This mainly depends on the type of Wheel loader used. On average, a wheel loader can easily lift to 20 cubic yards, while the largest loader can bypass 160,000 lbs landmarks.

Locate the machine in a higher position than the truck when it handles loading or unloading, which can save engine power and improve working efficiency to 40%. The cylinders can produce the maximum power when the angle between the bucket cylinder and rod cylinder reaches 90°. The excavator machine rod bears the maximum capacity when it is vertical to the ground. When it refers to trenching, the excavator should dig the sides of the trench first then the center of the trench, which can save much power. The digger should work with low speed and minimize the rotation radius as much as possible.

What is more, the excavator fuel oil should also be maintained to reduce the fuel consumption. Always use recommended type of fuel oil that is applicable even under extreme temperatures. The fuel oil must be replaced if it exceeds the limited using date. Impurities cause damage to the excavator machine, so measures should be taken to avoid entering any impurities when storing or filling the fuel oil. The fuel oil tank should be filled as specified, failure to do so could result in abnormality. And do not mix the fuel oil with different grades or brands together.

It’s worth mentioning that the regular maintenance for excavators constantly working in the water is quite crucial. The priority is the linkage of the machine, such as bucket and stick pins where the machine will lose the grease through the operation. Sealed bearings and lithium grease are the preferential solution. The lithium grease could resist the submersing in both fresh and salt water for one day. For the machines that are submerged or in contact with water for long time are suggested to be maintained on a daily base. Consistent monitoring of the bucket rotation and observe whether the pins are drying out of grease are also significant.

The frequency for greasing should also be increased, especially when the machine is undertaking the earth work in wet and sandy conditions. In some cases, the machine linkage from the bucket and stick pins would need to be lubricated two times a day depending upon the conditions. If the bucket needs stay in the water all the time, the operator shall constantly grease the joints manually, with once every hour at least being suggested.

Rust can also be a real issue with prolonged use around water, especially for the undercarriage. The grease-based formula can be deployed to reduce the corrosion, to protect the components.

Due to the concerns of cost, productivity, and expense of transportation, operators tend not to use long-reach excavators for dredging work in the water. In that case, the excavators and the matched barge are used more often, however, we suggest the set is equipped with quick couplers for easy change-outs.

The proper position for digging with an excavator will differ depending on the terrain, the size of the equipment, the location of the dig site and the nature of the job. 

The best way to set up a dig for success is to take the time to plan before starting. Organizing where the scoop pile will go and where to stage other needed materials will keep the dig safe once it is started. Reading site plans to identify underground hazards like wires or pipes will ensure the productivity and efficiency of a job. Take time to paint lines before digging to align the first dig. 

All of these steps help to create a safe working environment which is the first step to proper digging with an excavator.
