The proper gantry hoist is one of the best benefits of a 15 ton ganry crane. A good hoist can maximize productivity and promote safety while working with a 15 ton crane. The capacity of a hoist should be determined based on the type of materials being handled, the load weight, and the frequency of lifting. A chain hoist is a cost-effective alternative to a wire rope hoist, especially if manual labor is a significant factor in the operation of your gantry crane.
Class C (Moderate service) gantry cranes
A gantry crane is a piece of equipment with a single beam and two legs. It is used for lifting large, heavy objects and is suitable for indoor or outdoor work. Single girder and double girder cranes have capacities ranging from 30 to 200 tons. They are available in a variety of styles, including two-leg and semi-rigged.
A gantry crane can lift its full rated load capacity twenty times an hour. Because of this, there are few limitations in workload height. Typically, these cranes operate at a high rate, with approximately 600 motor stops per hour. They have a lifetime of 20,000 hours, but must be inspected frequently for safety reasons. Occupational Health and Safety Administration (OSHA) regulations require frequent inspections, and the inspection process is specific.
Class A (Heavy service) gantry cranes
A gantry crane is versatile and is useful for a variety of tasks, including warehousing operations. Warehouses often need cranes that are mobile and have the strength to move heavy loads. A Class A (Heavy service) gantry crane can do both. The advantages of a Class A gantry crane make it the best choice for these applications. Here’s why:
Class A gantry cranes are used in industries that require high load capacities, high speed and constant precision. Class A cranes are also ideal for industries such as power plants, foundries, and machine shops where the duty cycle is constant and the load is often 50 percent or higher. Meanwhile, Class B gantry cranes are used in warehousing and repair facilities, and can lift loads ranging from zero to occasionally full rated.
Class B (Heavy service) gantry cranes
In general, the duty cycle of a 15 ton Class B (Heavy service rated) gantry crane is from occasional full loads to no loads. Typically, the crane will handle five to ten lifts per hour. This crane is most often used in service buildings, warehouses, and foundries. However, there are exceptions to this rule. Some cranes may perform up to twenty lifts per hour.
The metal structure of a 15 ton gantry crane is made up of main beam, end beam, supporting legs, and end carriages. They are typically designed as truss or box structures, and can be either mobile or rail mounted. Each type of running mechanism has
