What is a long reach boom for excavators?

 Long reach boom is an attachment to an excavator with an exceptionally long arm that is used primarily for demolition and many other applications.It is the most popular extender,and is now also offered as a factory-installed option by almost every excavator manufacturer.

By choosing a longer arm, boom, your excavator can reach farther and dig deeper. This equipment is especially useful when the space is limited to, properly reposition the machine, such as to reach a slope.In addition to construction and mining sites, long reach excavator booms are also used for temporary projects such as digging river banks and other similar complex excavation tasks.

With structural grade tensile steel and heavy duty components, the long boom excavator boom can handle a variety of attachments for dredging, marine construction, surface mining, slope stabilization, demolition of buildings and structures, and other specialized projects requiring maximum reach and depth.

However, as its arm's length increases, the boom will lose some of its weightlifting ability and breaking power.Therefore,rather than being used to dig trenches, the long reach arm excavator boom is more often used to reach the upper levels of a building being demolished,and pull down the structure in a controlled manner.It has largely replaced the wrecking ball as the main demolition tool.

The main advantage of a long excavator arm boom is the accuracy and demolishing efficiency it offered.Equipped with long booms,an excavator can even be used to demolish very tall buildings.

The long boom allows the excavator to work in difficult and demanding work environments that other excavators cannot reach. This unique advantage gives it the reliability to handle any kinds of construction projects.




Specially designed for marble and granite excavation,the modern model of long reach excavator booms features a heavy-duty bucket that guarantees a long service life even in the toughest applications.The sturdy X-frame and reinforced arm make the boom provide greater stability when lifting and moving blocks sideways,making sure that it is suitable for various work needs.

Unlike regular excavator arms, long reach booms are designed with longer hydraulic cylinders to increase outreach and improve maneuverability.To keep high stability during heavy work, the excavator with long reach arm booms is equipped with a large counterweight to balance the weight of the long boom.It’s also a possible way to help maintain some of the boom’s digging power.

A 20-ton excavator can be connected to a 15.5-meter long reach boom. Larger excavators can be connected with a longer arm boom. In general, a 30-40 ton excavator can use an 18 meter long arm, while a 50-55 ton excavator can use an 18-21 meter long arm.Equipped with these useful long reach attachments,an excavator can be applied to water works, port construction, river and lake dredging, metro works and other engineering tasks,thus improving its multi-function performance.

The only disadvantage of a long excavator arm is the complexity of the transport process.Because it comes in a longer size, the boom needs to be disassembled into smaller parts in order to be transported more efficiently.The counterweight also needs to be transported separately due to its heaviness. However, long reach excavator booms are still the primary choice for many excavation and demolition jobs.

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

Long-Reach Excavator Advantages and Operating Guidelines

图片
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. Higher Standard   Strict technology and examination standards have been set to manufacture this machine, which guarantees its excellent construction perfor

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
