These two requires a driver to control the machines and buttons to safely transport the equipments. These materials are not lightweight so it needs to be handled efficiently in order to avoid accidents. These are useful especially when carrying heavy equipments or transporting the materials from one place to another. Amongst the heavy machines cranes, forklifts and bulldozers are the most popular and widely used equipment when making houses, building, and even using it inside a warehouse.Unlike a crane, forklift is fairly easy to use but it cannot carry heavy equipments unlike what cranes are capable of carrying. It is very important to know that the weight of the material before carrying it to avoid instability. Unlike cranes, forklifts can be driven by one person only who is well trained. All he needs to do is drive and put the forks in front of the machine up and down and insert the forks into the different pallet. Forklifts on the other hand, are mainly used in warehouses when they need to transport different materials from one place to another.

That would depend on how it’s centre of gravity is balanced, the material it’s made from (a 3 tonne crane made from polystyrene isn’t going to be able to lift much) and it’s load bearing structure.

The hoist moves the load up and down, the trolley moves the load right and left, and the bridge of the crane moves the load forward and backward.
The dimensions of a generic bridge crane could include the following: Trolley designed for maximum cross slope of 1%, End trucks designed for maximum longitudinal slope of 3%, NEMA 4 weatherproofing, Cold weather protection, emergency brakes that will stop the crane in 12 and act as a hold down (brake sufficient for a 50 MPH wind velocity), completely bolted construction to facilitate erection as well as disassembly for easy relocation, radio remote controls and a full length catwalk with access ladder on 1 leg. A hoist and trolley, which traverses across the bridge, provides a total of three axes of motion.

The railroad crane is largely used for maintenance work on railroads, as such it has flanged wheels so it may travel upon the tracks. There are simple ones that may be mounted onto a rail car, or more complicated models that must be custom designed. They are typically chosen for their height and lifting capacity and are an essential part of constructing tall buildings. The tower crane is a modern balance crane that can be either fixed on the ground or attached to buildings or other structures. The telescopic crane uses a number of tubes fitted one inside the other in its boom. Thus they can be assembled easily without outside help. The self erecting crane is a special type of tower crane that can actually lift itself from the ground which allows the next segment of crane to be placed. However they are still sometimes used when power would not be possible or cost effective. A hydraulic system extends and compresses these tubes so that the overall length of the boom may be altered. These are best for short term rescue or construction jobs. The manual crane is not in use as much since newer hydraulic cranes models which use electricity are available.
