WHAT ARE LONG REACH EXCAVATORS USED FOR?

 Excavators are considered to be very important machines, especially for the construction and mining industries, as they are used to excavate large amounts of ground from the surface. There are many excavator models on the market. Each excavator has a specific configuration for a particular excavation task. One particular model that is widely used is the long boom excavator. This type of machine is designed with a long boom, which is often referred to as an arm.

 

Long boom excavators are most commonly used for digging deep holes or trenches. Very often, long-arm excavators are used to digging rivers or lakes while being placed on a floating platform or barge. Some long reach excavator models are equipped with oversized counterweights designed to counteract the levering effect of the boom. When equipped with jack-ups and other similar attachments, long reach excavators can be used to reach high places. In addition, when equipped with a mechanical thumb attachment, the machine can be used to lift and move pipes, utility poles, and other similar objects.

Purpose of using a long-reach excavator

A long boom excavator is actually a tracked machine designed with a bucket and a stick for digging trenches and holes. Just like the tracked backhoe loader, the long reach excavator can be found on every major construction or mining site. Although it is the ideal machine for digging deep holes and trenches, the long reach excavator has a limited digging capacity. Its main part is the boom, while the rod section can be extended all the way to the bucket. Special hydraulic cylinders power the three main components: the stick, the boom and the bucket.

 

Designing a long reach excavator is a demanding task that requires more than simply attaching a long boom and a long rod to a standard excavator. Longer and larger cylinders are needed for longer reach and effective component movement. Long boom excavators need to be properly designed with balancing devices in order to not only counteract the weight of the boom but also to provide additional leverage. This extra leverage is created when the bucket is filled. Failure to incorporate the additional balancing device can result in tipping when the excavator tries to lift the loaded bucket.

 

As the name suggests, the long boom excavator has an extended arm between the body and the working boom, powered by the cylinders. The long boom is fitted with a cylinder operating system that powers the movement of the cylinders. All of these designs have doubled the working range of the bucket, which can climb higher, deeper and further. These significant improvements have made the long boom excavator a specialized excavation tool of great practical value for minerals, docks, storage, and rescue.

The benefits of using long boom excavators 

Specifically, long boom excavators offer the following advantages.

 

1. Wider range of applications

The long boom can work in harsh and extreme working environments that other excavators cannot reach. This unique advantage makes them reliable enough to handle a wide range of structures.

 

2. Higher standards

The machine has been manufactured with strict process and testing standards to ensure excellent construction performance.


3. Easy to operate

The long boom excavator is highly mechanized, with a simple working mechanism and easy operation, which improves work efficiency and saves labor resources.

4. High safety

The distance between the operator and the operating object is far, reducing the danger in the working process. And the strengthened structure greatly improves safety.

 

In addition, a number of guidelines should be followed when operating a long boom excavator to make the most of its advantages.


1. The long boom should not be overloaded.

 

2. The hydraulic cylinder piston rod should not be moved downwards and a safe distance should be left.

 

3. When turning around, the long boom should be 0.5m high from the ground.

 

4. The bucket load should meet the specified standard, overloading will shorten the life of the long arm and the whole machine.

 

5. Do not dig directly in rocky areas, crush the rocks before digging.

 

6. The excavator should not walk or turn around when the bucket is working.

Which parts make up an excavator

  Excavators pass many names-- diggers, track hoes, 360s, JCBs, as well as even rubber ducks. There's quite a bit of terms of excavators, as well. We can imagine the shape of an excavator, however what are the parts of an excavator called and what features do they carry out? While excavator layout continues to progress and also boost, the standard form has continued to be regular for years. Obviously, various designs from various manufacturers will certainly have individual excavator parts and also functions not common to all kinds. By the same token, a 1 tonne mini excavator will certainly not share all functions and capacities with a 15 tonne strong device. Nonetheless, they all consist of the exact same 3 sections as well as standard elements which we will discuss below. The 3 main parts of the excavator are the undercarriage, the body and the arms. The undercarriage is the most affordable area and is responsible for transferring the excavator to the working area and also includ

As its name suggests, the long-reach excavator   has an extended jib between the machine body and the working arm, which is powered by oil cylinder. The long arm is equipped with a set of oil cylinder operating system to provide power for the movement of the oil cylinders. All of these designs double the working range of the bucket, which can go higher, deeper and further. The great improvements make the long-arm excavator an especial digging tool for minerals, docks, storage and emergency rescue, which has great practical value.    Long Reach Arm and Boom To be specific, the long-arm digger has the following advantages:   1. Wider Applications   The long arm can work in the tough and extreme working environment where other excavators can ’ t reach. This unique advantage makes it reliable enough to handle various constructions.   2.

What Is an Excavator Boom?

  An excavator boom is a component made use of to operate an excavator, an item of heavy machinery utilized for excavating holes or otherwise moving huge quantities of product. The boom is the tilted arm that is affixed to the excavator itself as well as the arm is pinned to the boom. The arm is sometimes called the dipper or stick. A knuckle boom can relocate right or left according to the machine, unlike conventional booms which can just go up or down.The excavator typically consists of a base with tracks or treads attached to turning wheels, along with a system known as the house that turns 360 degrees so the operator can access product on all sides of the device without rearranging the entire system. The excavator boom prolongs off the front of your house, and it normally contains two items that articulate for better reach. A pail is mounted throughout of the excavator boom. This container is in charge of doing the digging in addition to for consisting of the materials to be reloca
