Overhead Cranes for Pellet Machinery Plants

Overhead cranes are indispensable lifting equipment utilized in manufacturing environments to transport heavy loads with efficiency and precision. These cranes are designed to traverse overhead runways or rails, allowing for the movement of loads across a designated area.

Common Types of Overhead Cranes:

Single Girder vs. Double Girder:

• Single girder cranes feature a single bridge girder supported by end trucks, offering costeffective solutions for light to moderate lifting applications.
• Double girder cranes, on the other hand, boast two bridge girders supported by end trucks, providing higher lifting capacities and greater stability, making them ideal for heavyduty operations.

Top Running vs. Under Running:

• Top running cranes run along rails mounted on the top of the building's columns or roof structure, offering efficient material handling solutions with increased lift heights.
• Under running cranes, also known as underhung cranes, operate on rails mounted beneath the runway beams, making them suitable for applications with limited overhead clearance.

Bridge, Gantry, and Jib Cranes:

• Bridge cranes traverse horizontally along elevated runways, offering versatility and coverage across large areas within the manufacturing facility.
• Gantry cranes, supported by legs on the ground, provide flexibility in installation and are ideal for outdoor applications or areas with limited overhead clearance.
• Jib cranes consist of a horizontal boom attached to a vertical support pillar or wallmounted bracket, offering a compact solution for specific work areas or tasks within the plant.
