QD Double Girder Overhead Trolley Crane application
The QD double-girder overhead trolley crane consists metal structure, a hoisting mechanism, a travel mechanism, an electrical system, and a safety device, five core components.
The metal structure bridge supports the entire structure. The electrical system provides power to the entire machine. The end beam running mechanism runs on tracks on either side of the plant building, enabling the crane to move longitudinally. The trolley on the main beam, driven by its drive mechanism, moves laterally, while the hoist mechanism on the trolley lifts the material vertically. Safety devices monitor the entire process, forming a closed-loop protection chain from load sensing to emergency braking. Through the coordinated movement of the overhead travel mechanism’s longitudinal motion, the trolley travel mechanism’s lateral motion, and the lifting mechanism’s vertical motion, cargo is moved from point A to point B.

Overhead cranes are widely used in workshops, warehouses, factories, steel mills, and other environments. They are mainly responsible for lifting and moving heavy materials. For safe and stable operation, overhead crane manufacturers equip their bridge cranes with various safety devices to prevent accidents such as overloading, collision, or mechanical failure. These safety components work together to monitor operating conditions in real time, protect operators and equipment, and effectively extend the life of the equipment. Understanding and maintaining overhead crane safety devices is crucial for enhancing operational safety, compliance, and productivity. Next, this article will introduce you to the overhead crane safety devices, so that you can recognize and understand their functions. What are the Overhead Crane Safety Devices？ The overhead crane safety devices are installed at different parts of the bridge crane. They are responsible for protecting and monitoring the safety, stability, and reliability of the crane during operation. These devices provide real-time monitoring and control of lifting, operational, electrical, and structural aspects to prevent accidents due to overloading, collision, rope breakage, derailment, or electrical failure.

An overhead crane, also known as a overhead travelling crane. It is a type of heavy-duty material handling equipment. The bridge crane, with its unique structure, spans above the factory building, steadily and accurately undertaking tasks such as material lifting and horizontal movement. Next, this article will introduce the overhead crane working principle, as well as its definition, types, parts, and other information. This will help you better understand bridge cranes so that you can choose the right overhead travelling crane solution. How Does An Overhead Crane Work? Overhead travelling cranes complete lifting tasks through the coordinated work of various parts and operator control. The bridge supports the entire structure. The end beam running mechanism runs on tracks on either side of the plant building, enabling the crane to move longitudinally. The trolley on the main beam, driven by its drive mechanism, moves laterally, while the hoist mechanism on the trolley lifts the material vertically. Through the coordinated movement of the overhead travel mechanism’s longitudinal motion, the trolley travel mechanism’s lateral motion, and the lifting mechanism’s vertical motion, cargo is…

When to do overhead crane maintenance? This is a particularly important topic. Among them, the stable operation of the bridge crane is certainly important, but more important is the daily overhead crane maintenance and inspection work to ensure the safety of the operators and people around the equipment. Next, this article will help you understand what the daily overhead crane maintenance and inspection involve. If you don’t know how to maintain an overhead crane, then this article will be your ideal guide. What Is An Overhead Crane? The overhead crane is mainly composed of the main beam, end beam, lifting trolley or electric hoist, electrical system and other main structures. Because its two ends are located in the concrete column or metal support, the shape is like a bridge, so it is called an overhead Travelling crane. Mainly used in production workshops, factories, construction sites, petrochemicals, warehousing and logistics, etc. When To Do Overhead Crane Maintenance? While maintaining efficient operation, overhead cranes must also ensure the safety of operators and people around the equipment. Therefore, daily inspections and regular maintenance…
What You Need to Know Before You Choose Choosing the wrong overhead crane creates problems that show up long after installation — in downtime, maintenance costs, and operational limitations. Overhead cranes are among the most widely used lifting systems in industrial facilities worldwide. They mount horizontally above the working area and move heavy loads accurately from point A to point B across the full floor coverage of a bay. But the different types of overhead cranes serve genuinely different purposes. A unit designed for a light-duty repair workshop is not the same machine as one built for a steel mill running three shifts. This guide covers what each type is, where it works best, what it’s made of, and what it typically costs — based entirely on the actual product range available from Voitto Crane. What Is an Overhead Crane? An overhead crane is a lifting system mounted horizontally above a workshop, production line, or warehouse. It moves heavy objects stably and precisely across the full working area below. The structure consists of one or two main girders, two end…
