Replacement Hydraulic Cylinders for Excavators

Bucket Cylinder

Excavators are commonly known as “bulldozers”, diggers, or JCBs. It is a member of the construction machinery family. At present, most construction machinery is mainly driven by excavators, so it can also be used as a category of construction machinery. Especially, the excavator is primarily composed of the following parts: a stick, and connecting rod. Additionally, the excavators, from India’s BUCKET cylinder assembly supplier, also include various transmission mechanisms, such as boom, bucket, arm construction, hydraulic cylinders, etc. For hydraulic cylinders, we may consider bucket cylinders, boom cylinders, and arm cylinders according to their different functions. As an exporter and trusted excavator parts manufacturer in India, LSR always provides quality bucket cylinder assembly products for the service of overseas customers.

What are excavator bucket and hydraulic cylinder, and How it work?

Generally, the bucket is located at the end of the stick (namely it is arm as usual). And also can be used for different purposes. (e.g. general purpose bucket, rock buckets and mud bucket, etc.). The excavator bucket always is connected to the arms and connecting rod. Meanwhile, the connecting piece is through the stick pin shaft and the connecting rod pin shaft. In additional, bucket cylinders are main part to drive the bucket movement and digging. The bucket oil cylinder of the excavator works through the hydraulic system. Thanks to the system including hydraulic pump, travel motor, pipeline and hydraulic oil. Absolutely, the quality hydraulic system may drive the bucket work well.

Excavator Boom Cylinder

The boom of excavator is a tilt arm attached to the excavator. Meanwhile, and the arm is fixed to the boom. Sometimes, the arm is called a bucket or a digger. The knuckle boom can move left and right along the machine, while the standard boom can only move up and down. Actually, the boom equips with excavator boom cylinder. This is the drive force to drive the boom to any direction. Normally, insiders call it as hydraulic excavators. excavator boom cylinder as one of the hydraulic cylinders, it is widely used in construction machinery industry. Certainly, it’s also an important actuator in the hydraulic transmission system. At the same time it is an energy conversion device that converts hydraulic energy into mechanical energy.

Types Of Hydraulic Cylinders

Depending on the application and industry, we also call hydraulic cylinders as hydraulic actuators or hydraulic pistons. Pneumatic actuators are often used to control processes that require accurate and fast response. This is because pneumatic actuators do not require large power. However, hydraulic actuators have a variety of directions, but the most common is the piston type. Meanwhile, these hydraulic excavator boom cylinder can be of different sizes. Additionally, excavator cylinders own different uses according to different sizes.

Which Brands Of Excavator Boom Cylinders Do We Carry?

Boom cylinders have an important job to do, but they are subject to many potential failures – any of which can cause your machine to shut down and thus hinder your work progress. For example, the barrel inside the boom cylinder can crack or wear over time as contaminants move through it, or the rod can be damaged by foreign objects or overload the excavator beyond its lifting capacity. When your boom cylinder needs to be replaced, you can rely on LSR for rebuilding or new surplus boom cylinders from major manufacturers. Such as John Deere, Caterpillar, Hitachi, Komatsu, Shinko, and many others.
