Tower cranes enable the construction industry to make some wonderful structures. These cranes have been used to reach ever-increasing heights. Tower cranes provide the way to lift and transport materials, tools and building parts all over a construction site. There are various components that assemble a tower crane when they are put together. Putting a tower crane together uses different pieces of construction equipment.
Normally, the tower crane base is made from a steel unit. The base is attached to a concrete pad that is custom-designed. This kind of set-up provides the structure with stability. Overall, the construction has to be well engineered and constructed in order to operate at optimum safety.
The tower cranes mast provides height to the machine. The mast is made of connected steel sections. The amount of parts determines the height of the crane. Normally, a tower crane has a design which allows the mast to grow during construction by adding more sections as the building process goes on. This way the height of the crane can be specified, making sure that it has enough height to safely and efficiently perform the required work.
At the top of the mast is the slewing unit. It houses the motor and equipment that enables the crane to rotate. A top climber is the piece of machine that allows the mast to grow. The top climber sits just underneath the slewing unit. Hydraulic rams inside the top climber enable the slewing unit to be disconnected from the mast by raising it higher.
The term "boom", refers to the working arm of a tower crane. The boom is made up of separate steel sections which are attached together, extending out from the top of the slewing unit and parallel to the ground. There is a trolley connected to the bottom which could run the length of the boom. This trolley has the hoisting mechanism.
When reaching up and overtop of obstacles mounted on floors, equipment and machinery, articulating man lifts are the perfect alternative. These machinery can reach elevated positions that are not easily accessed by a straight or telescopic boom lift.
An articulated boom lift or a cherry picker is a hydraulically powered lift which is used to reach the difficult to access, high areas above ground level. An articulated boom lift is controlled by the operator from a panel which is located in the bucket.
The various parts of the articulated boom allow it to travel in different directions. Like for example, a boom lift can travel both horizontally and vertically, as opposed to a scissor lift, that only has vertical travel capability. The boom lift can easily reach over big obstacles by being able to travel in opposing directions. This boom is supported by and attached to a grounded vehicle.
Construction crews and window fitters utilize boom lifts for is strong and stable platform on which to stand when working on the outsides of buildings. Tree surgeons and lamppost engineers as well as firefighters regularly utilize boom lifts.
