Electric overhead cranes are the workhorses of many industrial sectors, seamlessly lifting and transporting heavy loads with precision and efficiency. In factories, warehouses, and construction sites, these cranes play a pivotal role in streamlining operations and boosting productivity. However, behind their seemingly simple functionality lies a crucial aspect that often gets overlooked: speed.
When it comes to electric overhead cranes, speed is not a one-size-fits-all affair. Different tasks demand different velocities to ensure optimal performance and safety. Let's break down the speed specifications of these cranes:
These speed specifications is key to harnessing the full potential of electric overhead cranes. From horizontal traversing to vertical lifting, each speed parameter plays a vital role in optimizing crane performance and ensuring smooth operations in industrial environments. But there's more to crane speed than meets the eye. Stay tuned as we explore the factors influencing speed and how to customize it to meet your specific needs.
The speed of a crane mainly depends on its type and application scenario, including lifting speed, trolley travel speed, and bridge travel speed. These speeds are typically measured in m/s or m/min, as follows:
Lifting Speed/ Hosting Speed : This refers to the speed at which the crane lifts a load. Generally, the lifting speed ranges from 8-12 m/min. For heavy lifting, the speed might be between 0.3-8 m/min.
Bridge Travel Speed/Long Traveling Speed : This is the speed at which the crane moves along its tracks. This speed is usually faster, typically ranging from 2-20 m/min.
Trolley Travel Speed/ Cross Travelling Speed : For overhead cranes, the trolley's speed on the tracks is generally between 2-20 m/min.
Additionally, there is the gantry crane travel speed, which usually considers the operator's comfort and ease of operation. The standard speed is 20 m/min, but it can be slightly faster during idle operation, reaching up to 30 m/min. For special applications, custom speeds can be designed according to user requirements.
It is important to note that the self-traveling speed of the crane should not exceed 3 km/h in specific situations (such as on turntables, near end stops, entering/exiting buildings, etc.). These speed settings are intended to ensure the safe operation of the crane and the convenience of its operation.
