Tower Crane Accidents



Tower crane accidents are very dangerous events. A crane is usually hundreds of feet tall and the weight of it is also very substantial. You can imagine what a machine that consists of steel and concrete and is bigger than any building will weigh. This means that you need to make sure that no accidents happen and that all of your equipment is working properly.

Limit Switches of Tower Cranes



The crane utilizes two limit switches to determine that the driver does not over-burden the crane:

Parts of a Tower Crane



A tower crane consists of many different parts working together. The main parts are the lifting hook, pulleys, cables, jib, winch and the crane cab. The lifting hook is simply the hook from which things can be hung. The hook needs to be durable and in the right size in order to be of any use. A good hook is a necessary item for any crane being used. Next comes the pulley. The pulley is a mechanism which allows things to be lifted up and down. It works using cables and turning them at such an angle that things do not fall down once they are lifted.
