Tower cranes are able to have a maximum unsupported height of eighty meters or 265 feet. The maximum lifting capacity of a tower crane is sixteen thousand six hundred forty two kilograms or 39,690 lbs. with counter weights of twenty tons. In addition, two limit switches are used in order to make sure that the operator does not overload the crane. There is also one more safety feature called a load moment switch to make sure that the driver does not exceed the ton meter load rating. Finally, the maximum reach of a tower crane is seventy meters or two hundred thirty feet.
Due to their extreme heights, there is a science involved to erecting a crane. The stationary structure will first need to be transported to the construction location by using a huge tractor-trailer rig setup. Then, a mobile crane is used so as to assemble the machinery portion of the crane and the jib. These parts are then connected to the mast. The mobile crane then adds counterweights. Crawler cranes and forklifts could be some of the other industrial equipment which 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 could match the building's height. The crane crew utilizes what is referred to 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. Once complete, the slewing unit is able to detach from the top of the mast. In the top climber, hydraulic rams are utilized to adjust the slewing unit up an extra 6.1m or 20 feet. Next, the crane operator uses the crane to insert and bolt into place one more mast part piece.
The definition of a "loaded container" for the purpose of container handling and securing; is a container other than in the empty or tare condition. Containers must be treated as loaded, unless otherwise confirmed. To be able to maintain safety, when handling or securing containers, environmental conditions like wind should be taken into account. The term loaded is the container's maximum gross weigh rating. So as to ensure that the centre of gravity is kept as central and low as possible, the load needs to be distributed all over the container.
Having an evenly distributed cargo it is advantageous to prevent lack of vehicle stability, and excessive tilting, in order to maintain safety. An even load helps to prevent unacceptable load concentrations, and unacceptable vehicle axle loading.
The eccentricity of the center of gravity varies, with the distribution of load in the container. It is extremely important that the designers of containers and handling equipment take this into account during the engineering process. For example, when sixty percent of the load by mass is distributed in 50% of the length of the container measured from one end of the machine, the eccentricity corresponds to 5%.
Make certain that the container is free to be handled and care needs to be taken to make certain it is safely attached to the container, so as to make certain that the machine utilized is right for the cargo. Particular attention has to be paid to the risk of the container tilting due to the eccentricity of the center of gravity. When lifting any container whose centre of gravity is mobile or eccentric, such as a bulk container, a tank container or a container with a liquid bulk bag or a thermal container with a refrigerating unit, either integral or clip on, or any container with a hanging load, great care should be taken when lifting these.
