Overhead and gantry cranes are essential pieces of equipment in various industrial settings, including manufacturing, construction, and cargo handling. These cranes are designed to handle and transport heavy loads efficiently and safely. Here is a comprehensive guide to help you understand the components, types, and applications of these cranes.

Overhead Cranes

Overview

Overhead cranes are used for lifting and moving heavy loads within industrial facilities. They operate on an overhead runway system, allowing them to move freely without ground obstacles, thus reducing product damage and worker injuries.

Components of Overhead Cranes

• Bridge: The main component, consisting of the main beam, end beams, and a walking platform. The main beam is typically a box-shaped structure[4].
• Lifting Mechanism: Comprises a motor, reducer, drum, and brake. For cranes with a lifting capacity of 15t and above, there are often two sets of lifting mechanisms (main hook and auxiliary hook)[4].
• Crane Travelling Mechanism: Includes motor, transmission shaft, reducer, wheel, and brake. There are centralized and separate driving modes[4].
• Trolley Travelling Mechanism: The trolley moves along the bridge rail and is driven by a three-in-one motor or a two-in-one motor with an independent brake[4].
• Control Room: Houses control devices for crane and trolley movements, lifting mechanisms, and safety protection devices. The cab can be fixed or mounted below the trolley[4].

Types of Overhead Cranes

Overhead cranes come in four main configurations:
– Single Girder: Suitable for lighter loads and simpler applications.
– Double Girder: Offers stronger bearing capacity and is used for heavier-duty applications.
– Top Running: The crane runs on the top of the runway beams.
– Underhung: The crane runs under the runway beams[2].

Selection Criteria

To select the right overhead crane, consider the following:
– Rated Load: The maximum weight the crane can lift.
– Span of the Crane: The distance between the runway beams.
– Lifting Height: The maximum height the crane can lift.
– Type of Load or Material: Determines the type of rigging or attachments needed.

Gantry cranes are a variation of bridge cranes with two support legs installed under the main beam, allowing them to run on ground tracks. They are commonly used for outdoor cargo handling.

Components of Gantry Cranes

• Metal Structure: Includes the main beam, end beams, support legs, and lower beams. The main beam can extend beyond the legs to form a cantilever[3].
• Lifting Mechanism: Typically an electric hoist with a hook, grab bucket, or electromagnetic chuck[3].
• Running Mechanism: Includes trolley and crane running mechanisms, generally driven by three-in-one or two-in-one motors with independent brakes[3].
• Safety Protection System: Features lifting limiter, overload limiter, stroke limiter, bumper, and wind-resistant anti-skid device[3].

Types of Gantry Cranes

Gantry cranes can be classified based on several criteria:
– Gantry Frame Structure:
– Full Gantry Crane: Both ends of the main beam have support legs.
– Semi Gantry Crane: One end of the main beam has a support leg.
– Cantilever Gantry Crane: The main beam extends beyond the legs[3][5].
– Main Beam Structure:
– Single Beam Gantry Crane: Less expensive and simpler, suitable for loads below 20t.
– Double Beam Gantry Crane: Stronger bearing capacity, larger span, and better stability, recommended for heavier-duty applications[5].
– Main Beam Type:
– Box-Type: High safety and rigidity.
– Truss Type: Lower cost, lighter weight, and good wind resistance[5].
