How to Choose Excavator Booms - Glikr
Configuring an excavator for a specific application requires some planning. Many factors come into play, such as the working range of the boom and bucket bar, material density, required output, use of attachments and quick connectors, and lifting capacity requirements, to name a few.

Manufacturers offer a variety of bucket bar and boom options for midsize excavators. For example, Caterpillar typically offers heavy-duty (HD), extreme service, and long boom, depending on the model. Heavy-duty boom and bucket bar configurations are typically used for earthmoving applications. Extreme service rod and boom combinations are for demanding applications, such as demolition with a large number of attachments.
Long Reach Arm and Boom
The front end adds some weight compared to using a standard heavy-duty boom, so you will have less cycle time. But it is application-specific. When you're running hammers or scissors and multiprocessors continuously, you want the machine to last longer, so you turn to a boom and bucket configuration that can handle that kind of abuse.
You have every bucket bar option and every moving arm option, including extra-long reach configurations. You can see the maximum digging depth and maximum flat bottom depth for each machine.
Let the job be your guide
Contractors should understand the application they are using the machine for before selecting a combination of work equipment. General items to consider include job scope, haul size, productivity and bucket options needed, and whether one or more attachments have potential use.
Your primary bid for the job will determine the appropriate configuration. Underground contractors and basement excavators typically purchase long booms for optimum efficiency. Off-road pipelining or land clearing contractors will purchase medium arms for stability and optimum productivity. Large excavator contractors will purchase short arms for boom strength and optimum productivity.
Contractors digging trenches and putting in sewer/water lines often want to reach out, so they may order a long arm with a coupler and two buckets. If the contractor is adding an attachment such as a thumb, the person would order a mid-arm for added stability. If the contractor is digging into tough material, he'll buy a short arm for an extra breakout.

Long vs. short
In applications where a long boom/boom combination is used, the main benefit is an expanded working range that can add versatility to certain applications.

Longer moving arms and bucket bar options typically reduce arm crowding forces. Longer work equipment typically reduces lateral lift forces due to its greater impact on machine stability, while forward lift forces are more dependent on hydraulics. Shorter moving arm/boom options can have the opposite effect when the working range is limited.
Arm length is also directly related to the bucket size that can be used. The shorter the boom, the higher the boom force and the larger the bucket.
In all respects, it appears that a shorter arm will provide higher productivity. But in reality, it depends on the application and type of material the contractor is excavating. A shorter arm will fill buckets of hard materials faster; but with softer materials, an excavator with a shorter arm will have more movement and more pipe joints.
There are other trade-offs to consider. One disadvantage of shorter work equipment is a reduced working range that limits the ability to reach the desired depth or dumping height. The benefit of a shorter boom/arm combination is that the workforce is closer to the machine, so the operator typically experiences greater stability and can use a larger range of attachments and bucket sizes if the application requires it.

Long Reach excavator: How to choose the right one
How to choose the proper long reach excavator
Long reach excavators are needed for all kinds of work projects that require access to hard-to-reach areas. It is therefore important not to make a mistake when choosing this excavator to carry out the task at hand. In this case, a mistake can have serious consequences, ranging from cost overruns to unfinished projects.
The first step you need to take is to assess the technical specification of the long reach excavators, i.e. to determine the parameters on which you will choose the machine.In order to make sure that the investment in the machine pays off and that no additional costs are incurred, it is essential to assess the technical specification, which is the main criterion for selecting a long reach excavator.
In addition to power, the digging depth, maximum bucket size and other criteria must be considered.
The next step is to contact your sales representative to find out:
- how far away the machine is from a service centre;
- what experience has been gained in servicing this equipment;
- whether essential spare parts and maintenance tools (bearings, filters, etc.) are stocked locally, and what is the shortest possible lead time to obtain the necessary spare parts; and
- if the warranty period can be calculated on the basis of the hours worked.
When choosing a long reach excavator, most buyers are interested primarily in the price of the machine. In fact, the price of a long reach excavator is an important factor for buyers when purchasing specialist equipment, but it is not the right deciding factor. When choosing a long reach excavator or any other equipment, you should look not only at the price, but also at other features.
Of course, price is an important criterion, so compare the prices and conditions of sale to other models on sale. Long reach excavators are not cheap, and corporate funds are often in circulation, so you need to look for credit, which equipment dealers can also provide. For example, Cat dealership Avesco Baltics offers services of Cat Financial to local companies. These services are offered on flexible terms where, along with the machinery, after-sales service and maintenance, the financial solution can also be obtained from a single source.
Cat Financial transfers the requested equipment to the company that has opted for the operating lease service for a predetermined period of time (15 years). The customer pays the lease payments during the contract period and has the option at the end of the contract: return the machine to the company, extend the lease or buy a second-hand machine. This service is convenient for companies with long-term contracts, such as 23-year projects, where specific machinery is needed but it is difficult to plan whether it will still be needed after the end of the project.
The price-quality-performance ratio plays a very important role. Therefore, you should first identify the main types of work for which the long reach excavator is to be purchased, as well as the conditions under which the work will be carried out. If, for example, the long reach excavator will have to operate in restricted conditions, the depth and accessibility of the excavation is an important consideration here. The excavator's lifting capacity and the robustness of the structure (frame) are also important factors to consider.
Moreover, we should not forget the brand awareness in Baltic countries. Modern long boom excavators operate in harsh conditions, which places special demands on the quality and frequency of maintenance. It is often the case that cheaper appliances from lesser-known manufacturers are completely depreciated due to long delivery times for spare parts and lengthy repairs or servicing. In order to avoid unnecessary costs, it is recommended that you buy your long boom excavator only from well-known brands that have extensive service networks and ensure prompt servicing.
