Overhead Crane – Gantry Crane | China Heavy Crane …

Comprehensive Guide to Overhead and Gantry Cranes

Introduction

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 detailed guide to help you understand the components, types, and applications of these cranes.

Overhead Cranes

Components of Overhead Cranes

Overhead cranes are composed of several key components:

Bridge

• The bridge is the main structure of the overhead crane, consisting of the main beam, end beams, and a walking platform.
• The main beam is typically a box-shaped structure, and the end beams are connected at both ends of the main beam.
• The walking platform is equipped with safety railings and may include a cab or control room[4].

Lifting Mechanism

• The lifting mechanism includes a motor, reducer, drum, and brake.
• The motor is connected to the reducer, which in turn is connected to the drum. The drum winds or unwinds the steel wire rope to raise or lower the hook.
• For cranes with a lifting capacity of 15 tons and above, there are often two sets of lifting mechanisms: the main hook and the auxiliary hook[4].

Crane Travelling Mechanism

• This mechanism allows the crane to move longitudinally along the runway beams.
• It consists of a motor, transmission shaft, reducer, wheel, and brake. There are centralized and separate driving modes[4].

Trolley Travelling Mechanism

• The trolley moves laterally along the main beam, driven by a motor and reducer.
• The trolley frame includes the trolley running mechanism and the lifting mechanism. There are different transmission forms for the trolley running mechanism[4].

Control Room

• The control room houses the control devices for the crane and trolley mechanisms, lifting mechanisms, and crane protection devices.
• The cab can be fixed at one end of the main beam or mounted below the trolley to move with it[4].

Types of Overhead Cranes

Overhead cranes come in several configurations to accommodate different facility conditions and lifting requirements:

Single Girder Overhead Crane

• Features a single girder beam and is generally less expensive and simpler in structure.
• Suitable for lighter-duty applications[2].

Double Girder Overhead Crane

• Has a stronger bearing capacity, larger span, and better overall stability.
• Recommended for heavier-duty applications[2].

Top Running Overhead Crane

• The crane runs on a track mounted on the top of the runway beams.
• Suitable for facilities with high ceilings and heavy loads[2].

Underhung Overhead Crane

• The crane runs on a track mounted on the bottom flange of the runway beams.
• Ideal for facilities with lower ceilings and lighter loads[2].

Applications and Benefits

Overhead cranes are efficient, safe, and cost-effective solutions for industrial facilities. They can lift and transport heavy loads overhead without being disturbed by ground obstacles, reducing product damage and worker injuries. These cranes can use standard rigging or custom below-the-hook attachments depending on the type of load or material being lifted[2].

Gantry Cranes

Components of Gantry Cranes

Gantry cranes are variations of bridge cranes with two support legs installed under the main beam:

Metal Structure

• Comprises the main beam, end beams, support legs, and lower beams.
• Can be box-shaped or truss structure. 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 to handle various materials[3].

Running Mechanism

• Includes trolley running mechanism and crane running mechanism.
• Driven by three-in-one or two-in-one motors with independent brakes[3].

Safety Protection System

• Includes lifting limiter, overload limiter, stroke limiter, bumper, and wind-resistant anti-skid device[3].

Types of Gantry Cranes

Gantry cranes are classified based on their frame structure, main beam, and application:

Full Gantry Crane

• Has two support legs at both ends of the main beam.
• Suitable for both indoor and outdoor applications[5].

Semi Gantry Crane

• Has one support leg and one end of the main beam attached to a wall or other structure.
• Often used in situations where space is limited[5].

Cantilever Gantry Crane

• The main beam extends beyond the support legs to one or both sides.
• Useful for expanding the working range of the crane[5].

Single Beam Gantry Crane

• Features a single girder beam and is less expensive with a simpler structure.
• Suitable for load capacities below 20 tons[5].

Double Beam Gantry Crane

• Has a stronger bearing capacity, larger span, and better overall stability.
• Recommended for heavier-duty applications[5].

Applications

Gantry cranes are versatile and can be used in various settings:

General Gantry Crane

• Handles various materials or loads with lifting capacities up to several hundred tons.
• Can be equipped with different picking devices[5].

Shipbuilding Gantry Crane

• Used to assemble hulls and often features two lifting trolleys[5].

Container Gantry Crane

• Used at container terminals to stack, load, and transport containers.
• Available in rail-mounted and rubber-tyred types[5].

Gantry Crane for Hydropower Station

• Used for lifting, opening, and closing gates, as well as installation work[5].

Selecting the Right Crane for Your Application

To choose the appropriate overhead or gantry crane, you need to consider several factors:

Rated Load Capacity

• The maximum weight the crane is designed to lift[2][5].

Span of the Crane

• The distance between the support points of the crane[2][5].

Lifting Height

• The maximum height the crane can lift the load to[2][5].

Type of Load or Material

• The nature of the load being lifted, which determines the type of lifting mechanism and attachments needed[2][5].

Crane Working Environment

• Whether the crane will be used indoors or outdoors, and any specific environmental conditions it must operate in[2][5].

Operating Hours and Travel Distance

• How many hours the crane will operate per day and the distance it will travel, which affects the durability and maintenance requirements[2][5].

By carefully considering these factors, you can select an overhead or gantry crane that provides an efficient, safe, and cost-effective solution for your specific application.
