Structure of 3 ton overhead crane
The structure of 3 ton hoist crane mainly includes bridge travelling mechanism, electric hoist, bridge metal structure and electric motor. Electric hoist, the lifting mechanism of the crane, moves along the main girder. Its metal bridge structure is mainly composed of main girder and end girder. The main girder and end girder is rigid connected. There are wheels on the sides of end girder to sustain the bridge travelling. And I-type steel is welded on the main girder for electric hoist travelling.
Improve efficiency with the 3 ton overhead crane
When you need to lift heavy loads, you have to make sure you have the right equipment that is going to get the job done. The wrong equipment is going to cut profits and potentially cause an accident. When you are dealing with loads that weight multiple tons, you have to do your research and make sure you are getting the right crane for the job. Read on to learn about the 3 ton overhead crane and what the benefits of owning it are.
The 3 ton overhead crane is strong, yet it is also compact. This crane is light and small and works well with an electric hoist. There are multiple types of 3 ton cranes to choose from, including the under hung, overhead, single girder, and double girder cranes. You can find this crane in factories, stock yards, warehouses and other situations where material needs to be lifted.
Common crane can’t be used in situations where there is flammable, corrosive or explosive situations, but this crane with explosion-proof hoist can be used in serious environment. The crane is made of four main parts. The main girder is what gives this crane strength. The traveling mechanism goes along the girder and the electric hoist runs on the traveling mechanism to lift and move loads along the girder. The last important part of this crane are the controls.
When you are choosing a crane you will find that there are two types of controls, the ground controls and the cabin controls. You can choose to have the cabin installed on either side of the crane and you can also choose an open or a closed cabin. You also need to decide which type of overhead crane you are going to need.
The single girder overhead crane has one girder and is the lightest of all the cranes since it only has the one girder. It resembles a bridge and also has safety protection to protect the operator. The single girder crane is made with high quality steel and has a u-shaped slot which is good at resisting external forces. The girders are connected with bolts which allow you to set up and take apart the crane easily.
The double girder crane is stronger since it has an additional girder and it can handle more weight. You can buy the crane in both medium and heavy duty class depending on how much lifting you need to do. The heavy class crane is appropriate for continual lifting. These cranes feature a double brake system for additional safety.
The top running overhead crane saves space and is good for factories that have less room. The under hung crane works well when space isn’t an issue. When you are getting ready to buy your crane, you need to know what you are lifting and where the crane is going to go. There are many factors you need to consider when you are buying a crane and you want to make sure that you end up with the right 3 ton overhead crane for your needs.
Overhead crane inspection checklist
Designated personnel may perform required maintenance and repairs on overhead crane systems. The crane operator should conduct inspections on a daily basis before and after use. A daily inspection checklist should be used and singed off on to ensure an effective and thorough assessment.
Daily safety inspection must be conducted by the crane operator each day, and prior to use at the beginning of each shift. To start, the operator should ensure that all required safety equipment good condition. The operator should also be trained and authorized to use the crane.
After the operator make sure all safety devices normal condition, he/she should check to see if the crane/hoist has been locked-out or tagged-out. The control of hazardous energy or lockout/tag out must be used to de-energize the crane. Before the operator begins the safety inspection, he/she should asses the area around the crane for potential safety hazards.
