Are you a 125cc motorcycle owner looking to squeeze every last drop of performance from your bike? Many riders believe that dyno tuning is only for larger displacement engines, but that couldn’t be further from the truth. Optimizing your small-capacity machine can dramatically transform its rideability and power output. Your 125cc motorcycle has potential beyond its factory settings, especially…

Are you looking to squeeze every last drop of performance from your 125cc engine? Many riders and enthusiasts strive for optimal power, efficiency, and reliability, yet often resort to guesswork when tuning their machines. This hit-or-miss approach can lead to frustration, wasted time, and even potential engine damage. The solution lies in precise, data-driven analysis. To truly understand and…

Precision Testing Starts with Intelligent Motor Control

In applications such as dynamometer systems, test stands, and industrial load testing, variable frequency drives (VFDs) offer precise control over motor speed, torque, and load simulation. VFDs support a wide output frequency range (up to 500Hz or higher) and enable fine-tuned adjustments, making them ideal for replicating complex, real-world operating conditions. With features like sensorless vector torque control, encoder-based closed-loop feedback, and real-time analog/digital inputs, VFDs deliver the responsiveness and accuracy required in advanced testing environments.

Built-in data logging, torque limiting, and dynamic braking functions give engineers the tools to monitor system behavior under a range of stress conditions. Whether you're conducting R&D, endurance testing, or quality control, VFDs offer repeatable performance and precise load profiling, essential for today’s high performance industrial testing applications.

The VFD Exchange

The Crane Load Test Dynamometer by MATCHAU is a high-precision device used to measure and validate the load capacity of cranes and lifting equipment. It ensures safe and efficient lifting operations by providing accurate weight readings, contributing to enhanced safety and compliance in industrial settings.

Crane Load Test Dynamometer Types

Wireless Dynamometer

Also known as a wireless dyna-link, the wireless dynamometer is a set that includes one load cell, two shackles, and one wireless handheld indicator. You have the flexibility to choose the components you need, and it’s not an issue if you don’t require all of them.

Load Cell Shackle

MATCHAU’s load shackles, also known as wireless crane scales, are a perfect addition to our standard dynamometer version. They are particularly useful in scenarios where traditional dynamometers may restrict distance or movement, or when safety considerations necessitate a larger gap between the operator and the load shackles.

Why Is Crane Load Test Dynamometer Important?

Safety Assurance: Crane Load Test Dynamometer is essential for verifying that cranes and lifting equipment operate within their safe working load limits, preventing overloading and ensuring the safety of personnel and assets during lifting operations.

Compliance Verification: The dynamometer helps ensure compliance with safety regulations and industry standards, allowing businesses to meet legal requirements and maintain a safe working environment.

Equipment Reliability: Regular load testing with the dynamometer helps identify potential issues and weaknesses in the crane or lifting equipment, enabling timely maintenance and enhancing overall equipment reliability, reducing downtime, and extending the equipment's lifespan.

Jika berbincang mengenai pengujian dan juga pengukuran pada performa sebuah mesin, tentu hal tersebut tidak dapat dipisahkan dari pengujian yang dilakukan dengan menggunakan Engine Dynamometer maupun Chassis Dynamometer. Karena kedua pengujian tersebut memang memiliki fungsi yang sama, yaitu untuk melakukan pengukuran pada performa maksimal serta pengujian pada mesin, baik itu kendaraan atapun mesin pabrikan.

Untuk kesempatan kali ini, kita akan berfokus pada alat Engine Dynamometer, walapun memiliki fungsi yang sama dengan Chassis Dynamometer. Engine Dynamometer ini memiliki cara kerja yang berbeda, cara kerja dari alat tersebut adalah dengan memasangkan mesin menuju ke absorber dari alat pengujian, seetlah itu mesin akan mulai mengukur torsi, kecepatan maksimal dan juga rpm dari mesin tersebut, pengukuran ini juga menggunakan semacam sistem dalam pengujiannya.

Untuk absorber pada alat ini, ada beberapa macam absorber yang bisa digunakan untuk pengujian engine dynamometer ini, seperti Water Brake Absorber, motor listrik dan juga juga eddy current absosrber. Selain itu, pengujian ini juga bisa dibagi menjadi 2 kategori pengujian yaitu pengujian akselerasi dan juga pengujian steady state. Diantara kedua metode pengujian tersebut pengujian akselerasi lebih banyak digunakan, karena dalam sistem pengujiannya, metode ini dapat memberikan representasi kurva pada torsi atau daya yang lebih luas dan juga lebih cepat.

Akan tetapi, ketika menggunakan loadcell dalam pengujiannya, ada beberapa alasan yang membuat kenapa output power pada mesin tidak dapat diuji, salah satu masalah yang sering terjadi adalah karena gesekan dari mesin, baik itu gesekan mekanis ataupun itu gesekan aerodinamis pada kopling yang menuju ke dynamometer, hal ini dapat menyebabkan berkurangnya daya yang bisa ditransfer menuju ke alat dynamometer.

Selain digunakan untuk melakukan pengujian pada daya dan juga torsi maksimal pada mesin atau pada sebuah kendaraan, beberapa jenis dari engine dynamometer juga bisa digunakan untuk melakukan pengujian pada inersia dalam pengujian engine. Dengan melewati beberapa tahap dan proses pengujian, dan juga dengan memanfaatkan software yang sangat mendukung dalam proses tahap pengujian pada mesin.
