There is a great convenience when utilizing a scissor lift, because the convenience of working and the lift basket's security gives peace of mind when attempting to perform tasks that would have otherwise needed using the step of a ladder. The safety risks involved with this machine make it the best option for completing tasks from heights.
Nearly all scissor lifts are powered electrically by batteries which have been mounted directly onto the equipment. These batteries would need to be charged after a long shift or after sitting for extended periods without use. It is an easy task to charge the batteries. This can be done without any specialized equipment or tools and needs no heavy labor.
In order to prepare the scissor lift for charging, park the machinery near an electrical outlet. Make sure you are doing this in a well-ventilated place. Next, in order to prevent another operator from driving away with the lift plugged in, press the emergency shut-off switch. The emergency shut off switch is the big red button situated near the control box or the charger, inside the lift basket. Find the battery charger on the right side of the base of the lift. Normally, older models will have the charger mounted on the rear of the lift.
Then, plug the charger into the AC extension cord. Be certain you are charging in an area that is well ventilated and afterward plug the extension cord into an electrical outlet. In order to prevent accidental damage from being run over, the length of the electrical cord on the battery charger is purposely short. This is because if any extra length were to drop out of the battery charger storage place when in use, extreme danger can potentially take place.
Tower cranes enable the construction industry to build various incredible structures. These cranes have been used to reach ever-increasing heights. Tower cranes offer the way to raise and move materials, tools and building parts around a construction location. There are several different components which assemble a tower crane when they are put together. Putting a tower crane together uses various pieces of construction machines.
Base
The base of a tower crane is usually made from a steel unit. The units' base attaches to a custom pad made of concrete. This set-up gives the structure stability. Overall, the construction should be well engineered and constructed in order to operate at optimum safety.
Mast
The mast on the tower crane provides the machine with its overall height. The mast is constructed out of separate steel parts which are attached together. The amount of parts determines the height of the crane. Usually, 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 could be specified, making sure that it has adequate height to safely and efficiently perform the required work.
Slewing Unit/Top Climber
At the top of the mast is the slewing unit. It houses the motor and equipment that allows the crane to rotate. A top climber is the piece of machine which enables the mast to grow. The top climber is located just below the slewing unit. Hydraulic rams in the top climber allow the slewing unit to be detached from the mast by raising it higher.
Boom
The term "boom", refers to the tower crane's working arm. The boom is made up of individual steel sections that are attached together, extending out from the top of the slewing unit and parallel to the ground. There is a trolley attached to the base that can extend the length of the boom. This trolley has the hoisting mechanism.
