Cranes are typically used to raise and lower objects. Cranes from leading single and double girder overhead cranes suppliers are commonly found on construction sites and in factories. Cranes are also used in a variety of different places, such as warehouses. The principal function of a crane is to hoist or lower big objects that other equipment is unable to hoist.
Introduction
Cranes assist in the transportation of oversized loads from one area to another. A crane is a large machine with a complex structure. Individual industrial power tools, such as chains, hoists, wire ropes, sheaves, and so on, are also contained within a crane.
All of the various tools work together to accomplish a particular task of the crane. MIT Hoist, one of the leading double girder overhead cranes suppliers has a wide range of material handling equipment and machines.
We will principally address two types of EOT cranes in this post: single girder cranes and double girder cranes.
Choosing the Right Crane is Important
You must first know what a single girder crane and a double girder crane are before you can pick among them. Even if you’ve never heard of a bridge crane before, this article will describe what they are and how to choose the right one for your needs. Continue reading to learn more about the key differences between single and double girder cranes from leading double and single girder overhead cranes suppliers.
The key difference between the single girder crane and double girder crane is completely dependent on these two criteria—
- 1. Structural differences
- 2. Functional differences
Structural Differences
There is only one girder in the complete structure of a single girder EOT crane. In contrast, a double girder has two girders. What are girders, exactly? Girders basically are the metal beams that link the side travelling mechanisms in layman’s terminology.
In a single girder, an electrical hoist moves on the lower flange of the sole and main girders. The twin girder crane does not have a hoist. Rather, it employs a crab-shaped mechanism that traverses both girders.
EOT cranes, which use a single girder for component repair, do not need multiple cross-traveling rails and platforms. Others, on the other hand, must adhere to these guidelines.
Continuous platforms are not available in single girder cranes. In total, there are 3 platforms: 2 minor ones for the motor and another for panel repair. A double girder machine has a continual platform and a separate platform in addition to the crab-shaped frame.
There are no defined schedules for factory experts and technicians. Occasionally, they are compelled to work overnight. Double girder machines are preferred in these instances since they incorporate under bridge lights, which lessen the likelihood of accidents. This capability is not available on EOT cranes with a single girder.
The engines and gearboxes of these cranes also differ greatly. Single-girder cranes come standard with flange-mounted engines and modular gears. Foot-mounted engines and horizontal gearboxes are common features of double girder cranes.
Functional Differences
The pendant and radio remote system can be used to supervise a single girder crane. You won’t be able to do so, though, since you don’t have access to the control box. All three variants are offered with a double girder EOT crane.
The controllers of a single girder crane can use a snapping action limit switch to manage the hoist’s up-and-down operation. The switch’s function is activated by a wire rope guidance. On a double girder crane, a geared rotary limit switch helps to control the crane. That technology is qualified to determine the movement of the hook as well as regulate its up-and-down movement.
The greatest span and lifting capacity of each functional region is likewise variable. The maximal functional area of a single girder crane is roughly 30-40 meters. It can hoist a ten-ton load at a time. In comparison to a single girder crane, a double girder crane has a substantially bigger functional area and strength to lift capacity. With this tool, you can hoist and shift weights of up to 500 tones.
Price Comparison
Single girder cranes— ideal for smaller and lighter loads and can easily handle deal with common materials. They are less expensive but maintenance is a little higher!
Double girder crane— ideal for any application and can handle materials of all types. They are quite costly but more manageable and economical to maintain on an everyday basis.
