Typical Loads Handled

Precast Railroad Sleepers

Precast railroad sleepers, also known as ties or crossties, are foundational components of railway tracks. These sleepers are typically made of concrete or wood and serve as the support for the rails. The size of precast railroad sleepers can vary, but a standard concrete sleeper measures approximately 8 to 10 feet in length, 10 inches in width, and 5 to 7 inches in height. The weight of a concrete sleeper is substantial, ranging from 250 to 400 pounds, depending on the design and materials used.

Handling precast railroad sleepers requires specialized equipment due to their significant weight and the need for precise positioning. Gantry cranes, with their robust construction and high load capacities, are instrumental in lifting and placing these heavy components. The adaptability of gantry cranes ensures that they can efficiently handle various sleeper designs, contributing to the seamless construction of railway tracks.
