Crane Buffers

We manufacture more than 600 various ranges of crane buffers

Due to advancement in crane technologies, cranes have become of higher capacity and faster in speed. It is also because of this reason Collision risk has increased dramatically.

Crane buffer is a safety device that protects cranes from damage and collision. Adonitech crane buffers are well equipped and protect the crane operator & area in which the crane operates from impact & collision.

Our Crane Buffers are designed to provide exceptional energy absorption and ensure safety in demanding industrial environments. With a robust, large-bore design and superior shock-absorbing capacity, these buffers are ideal for protecting heavy or super-large equipment such as cranes, rail systems, and machinery used in industries like steel, coal, and railways.

Built for reliability, these buffers excel in decelerating equipment smoothly and safely, even under high-impact conditions. Equipped with a nitrogen-charged return system, they reset quickly, minimizing downtime and ensuring consistent performance.

Product Overview

Quantity	Model	Description
4	EL 120*100	FS – Flange Front, RS – Flange Rear, B – Protective Bellows, C – Safety Cable

Model Description Breakdown

Code	Explanation
4	Quantity: Specifies that you need 4 units of the product.
EL	Model or series of the product.
120	Represents the buffer stroke (distance the buffer compresses).
100	Indicates the maximum energy absorption capacity or other key specifications.
FF	Flange Front: Mounting option, the buffer will have a front flange for installation.
FR	Flange Rear: Mounting option, the buffer will also have a rear flange for flexibility in installation.
B	Protective Bellows: Protective covering to shield the buffer rod from dust, dirt, and contaminants, increasing durability.
C	Safety Cable: Ensures the buffer remains secure and prevents it from detaching or falling in extreme situations.

Application Data for Buffer Configuration

The following information is necessary to configure the right buffer for your application:

Vertical/Horizontal Motion

Specify if the buffer will be used for vertical or horizontal movements.

Weight

Indicate the weight of the moving object or load in kilograms.

Impact Velocity

Provide the speed at which the object impacts the buffer (in m/s).

Propelling Force (if any)

Mention any external force propelling the load, such as a motor, gravity, or manual force.

Cycles/Hour

Indicate how many times the buffer will be used in one hour (frequency of operation).

Temperature/Environment

Specify the operating temperature range and environmental conditions (e.g., dusty, wet, chemical exposure).

Applicable Standards

Mention any industry or safety standards the buffer must comply with (e.g., ISO, DIN).
