One type of fixed crane is the tower crane.
A tower crane is basically a balance crane in its modern form. Tower cranes typically provide the most usefulness due to their combination of lifting capacity and height, thus making them a must have when constructing tall buildings.

When using such a crane on a construction site, or any other type of site, and a load drops from it, it is almost impossible to stop the load from hitting the ground or anyone in its path. It抯 also quite difficult to issue a warning to workers below to move out QTZ125A Tower Cranes of the way. Such an accident can lead to very serious injury or death. Approximately 90% of accidents involving cranes are the result of human error. As such, it is essential to fully and properly train all crane operators and institute on site safety regulations and preparation. Simply by ensuring that workers who are operating cranes on the job are fully educated in their safe operation, most potential crane accidents can be avoided.
Before even commencing the operation of a tower crane, it is important that the operator fully assess its characteristics, such as the weight of the crane, the host rope抯 rating for the load, how is the load being attached and is it being done properly. These are examples are the many different assessments an operator must take into consideration to make sure the crane is safe for operation.
The operation of a tower crane does not solely involve the one who is at the controls of this machine. There is also a 搑igger?or 搒wamper? who is, in essence, a signaler to the operator. The operator and the rigger stay in...
