An aerial work platform truck, also called an aerial ladder, cherry picker, crane truck, mobility lift, or mobile tower crane, is a very versatile mechanical device used to offer temporary access to elevated areas, usually in height. Usually the work area is higher than the sidewalks and usually not accessible by traditional ways such as stairs, ramps, ladders or handrails. The lift has to be very sturdy so it doesn’t damage the surrounding property and must be controlled and serviced properly in all types of weather conditions. Since the machine is operating at greater heights, it may also be required to make turns at slower speeds than vehicles traveling in most traditional ways.
The aerial work platform is often seen as the cherry picker of the construction business. It is used in a variety of situations where conventional ladders or rails cannot safely get the job done. For instance the crane truck is used when lifting very heavy objects over fences or other barriers that usually cannot be reached by a regular ladder. It is safer to use an aerial work platform truck than constructing a straight ladder or railings because the vehicle will move at the same speed as the work being carried out.
Another example is when an individual needs access to a structure that does not have any type of exit plan. Typically this vehicle would not be able to get onto a normal set of ladders or rails xe nang may dau 2.5 tan. When an aerial work platform truck is used, there are several different methods that can be used to raise or lower the platform without damaging the area being worked. Some of these methods include lowering cables attached to the aerial lift by a crane or using a control mechanism that causes the vehicle to slowly raise the platform with the assistance of pulleys. Sometimes hydraulic means of lowering the platform can cause injury to the workers due to its weight. Therefore the proper method of lowering the platform needs to be carefully evaluated and practiced by all aerial work platform truck operators.
When raising an aerial work platform truck the weight of the crane also needs to be considered. The lifting capacity needs to be determined so that the aerial work platform truck can safely lift and move the object. This information needs to be obtained from either a professional source or from the manufacturer of the aerial work platform truck and from there it should be determined what the maximum acceptable weight should be for the vehicle. If the operator of the aerial work platform truck is not trained in this particular area there can be serious consequences to the people that are working on the project because if the weight limit is exceeded then the vehicle could tip over and injure those on it.
Aerial work platforms are often used on larger projects where conventional ladders cannot be installed. Larger projects such as bridges need to be raised a certain distance above the ground and most operators do not have access to conventional ladders that would allow them to accomplish this task. Aerial work platforms are also commonly used when installing large communication systems such as telephone lines and television cables that need to be installed above ground. The use of aerial work platforms has also become more common during construction projects where the work is spread out over a large area. Once the project is complete the aerial work platform is removed and the work is done with more traditional methods.
A good aerial work platform truck should be able to raise, lower, place and retrieve the platform on its own. Poor quality trucks will often lower the platform improperly and then the person operating the truck will often have trouble returning it to the top position themselves. Poor quality trucks will also typically not have the necessary equipment to perform the job correctly and will often fail to do their job at all. Many operators of these trucks have been injured at other jobs because they operated the aerial work platform truck in an unsafe manner. Avoiding injuries is the best way to ensure that operators use aerial work platform trucks carefully and with the utmost safety.
