3-ton overhead cranes are designed to lift loads weighing up to 6,000 pounds. They are commonly used in industries like shipping and manufacturing to move heavy materials or goods around. These cranes come in quite a few different styles. Keep reading to learn more about the various types of 3-ton overhead cranes that are available. This will make it easier to decide which crane style is the best choice for your specific application.
Single-Girder And Double Girder Overhead Cranes
Single-girder overhead cranes are designed with one girder, while double-girder cranes have two girders that run parallel to one another. The majority of 3-ton cranes feature a single-girder design. The only exception is if the crane is being used in a location where there isn’t a lot of overhead clearance. Using a double-girder design in situations like these allows the trolley to be mounted above the girders, reducing the amount of clearance required.
These traditional 3 ton overhead cranes are usually mounted inside of buildings. The girder spans the width of the building and is attached to special tracks that run along either side. This enables the crane to move from one end of the building to another. A trolley and hoist are attached to the girder and can move back and forth along its entire length. By moving the girder along the tracks and then adjusting the position of the trolley, the crane operator can access just about any area underneath the crane.
Gantry Cranes
These freestanding cranes feature a girder that runs overhead. On either end of the girder, there is an attached leg that extends all the way to the ground. The base of each leg is equipped with wheels, enabling the crane to easily be moved around.
Some gantry cranes are fixed, meaning that they are always the same width and height. Others are adjustable. Adjustable cranes allow you to change the width or height of the crane, depending on how it is being used. Adjustable cranes are a little bit more versatile since they can be used in a variety of different settings or circumstances.
Mobility is one of the biggest benefits of choosing a 3-ton gantry crane. Thanks to the attached wheels, you can use these cranes just about anywhere, making them a versatile choice for your business.
Jib Cranes
3-ton jib cranes are often used near workstations. These cranes have an arm that extends outward from a fixed base. They can be mounted to the wall, with the arm of the crane extending out into the building. They can also be mounted on freestanding pillars.
Freestanding jib cranes are usually capable of rotating 360°. That means that they can cover a circular area around the base of the crane. Wall-mounted cranes, on the other hand, can usually only rotate 180° since their movement is limited by the wall. The trolley and hoist can move along the length of the arm, accessing any area that falls underneath.
These are examples of some of the most popular types of 3-ton overhead cranes. Consulting directly with a crane manufacturer is an effective way to figure out which style is the most suitable for your business.
