Tower cranes may have a max unsupported height of eighty meters or two hundred sixty five feet, while the minimum lifting capacity of a tower crane is 16,642 kilograms or thirty nine thousand six hundred ninety pounds with counter weights of 20 tons. In addition, two limit switches are used to be able to make certain that the operator does not overload the crane. There is even another safety feature known as a load moment switch to make sure that the operator does not exceed the ton meter load rating. Last of all, the tower crane has a maximum reach of two hundred thirty feet or 70 meters.
Because of their extreme heights, there is a science involved to erecting a crane. The stationary structure will first need to be brought to the construction location by utilizing a large tractor-trailer rig setup. Next, a mobile crane is utilized in order to assemble the machine part of the jib and the crane. These parts are then attached to the mast. Next, the mobile crane adds counterweights. Crawler cranes and forklifts can be a few of the other industrial machinery that is typically utilized to erect a crane.
As the building is erected, mast extensions are added to the crane. This is how the crane's height can match the building's height. The crane crew utilizes what is known as a climbing frame or a top climber that fits between the top of the mast and the slewing unit. A weight is hung on the jib by the work crew in order to balance the counterweight. When complete, the slewing unit is able to detach from the top of the mast. In the top climber, hydraulic rams are used to adjust the slewing unit up an additional 6.1m or twenty feet. Next, the crane driver uses the crane to insert and bolt into place one more mast part piece.
A "loaded container" by definition is a container other than in the empty or tare condition, in reference to container handling. Unless otherwise confirmed, containers must be treated as loaded. To be able to maintain safety, when handling or securing containers, environmental conditions like for example wind has to be taken into consideration. The word loaded is the maximum gross weigh rating of the container. So as to guarantee that the centre of gravity is kept as low and central as possible, the cargo should be equally distributed throughout the container.
Having an evenly distributed load it is beneficial to avoid lack of vehicle stability, and excessive tilting, in order to maintain safety. A cargo that is even helps to prevent unacceptable load concentrations, and unacceptable vehicle axle loading.
With the distribution of load in the container, the eccentricity of the center of gravity varies. It is very essential that the designers of containers and handling equipment take this into account during the engineering process. For instance, when sixty percent of the load by mass is distributed in 50 percent of the length of the container measured from one end of the machinery, the eccentricity corresponds to 5%.
Make certain that the container is free to be handled and care needs to be taken to make sure it is safely attached to the container, in order to make sure that the machine used is perfect for the load. Specific attention mus be paid to the possibility of the container tilting because of the eccentricity of the center of gravity. When raising any container whose centre of gravity is eccentric or mobile, like a bulk container, a tank container a thermal container with a refrigerating unit or a container with a liquid bulk bag, either clip on or integral, or any container with a hanging cargo, extreme care must be taken when raising these.
