When searching for bridge crane end trucks for sale, you’ll encounter various types, each designed for specific applications and crane configurations. Understanding these distinctions is crucial for selecting the right fit for your operational needs.
Top-Running End Trucks
Top-running end trucks are the most common type, characterized by their wheels running on top of the runway rails. The bridge girders are typically mounted on top of these end trucks, allowing the crane to maximize hook height within the building’s structure.
These are generally used for higher capacity cranes and offer excellent stability. They are robust and can handle significant loads, making them a popular choice for heavy-duty industrial applications where maximum lifting capacity and floor space utilization are critical.
Under-Running End Trucks
In contrast, under-running end trucks operate with their wheels running on the bottom flange of the runway beam. The bridge girders are typically suspended underneath these end trucks. This configuration is often chosen when the building structure cannot support top-running runways or when a smaller capacity crane is sufficient.
Under-running cranes are typically lighter duty but offer advantages in certain architectural designs or when space constraints dictate. They are also known for their ability to provide excellent side clearances, which can be beneficial in crowded facilities.
Single Girder End Trucks
Single girder end trucks are designed to support a single bridge beam. This configuration is generally found on lighter capacity cranes (up to 15-20 tons) and for shorter spans. They are often more cost-effective and lighter, making them suitable for a wide range of general manufacturing and warehousing applications.
The design is simpler, often leading to easier installation and maintenance. However, they may not offer the same level of stability or capacity as their double girder counterparts for extremely heavy loads.
Double Girder End Trucks
Double girder end trucks are engineered to support two parallel bridge beams. This design provides superior strength and stability, making them ideal for heavy-duty applications, longer spans, and higher lifting capacities (often exceeding 20 tons). The hoist typically runs on rails mounted on top of both girders.
Double girder cranes allow for greater hook height, as the hoist sits between the girders rather than underneath. This configuration is preferred in steel mills, foundries, and other environments where robust performance under extreme conditions is required.
Custom & Specialized End Trucks
Beyond standard types, there’s a market for custom and specialized end trucks. These might include features like specialized wheel materials for specific rail types, corrosion-resistant coatings for harsh environments, or explosion-proof motors for hazardous locations.
