There is a great convenience when using a scissor lift, since the ease of working and the lift basket's security gives peace of mind when attempting to perform tasks that could have otherwise required working off the step of a ladder. The safety risks involved with this particular machine make it the best alternative for carrying jobs from heights.
The majority of scissor lifts are operated by batteries which are internally mounted in the base of the lift. These batteries have to be charged following a long shift or due to sitting after extended periods without use. It is an easy job to charge the batteries. This could be carried out without any specialized tools or equipment and requires no heavy labor.
In order to prepare the scissor lift for charging, park the equipment near an electrical outlet. Make sure you are doing this in a well-ventilated place. Then, so as to avoid another operator from driving away with the lift plugged in, press the emergency shut-off switch. The emergency shut off switch is the large red button located near the charger or the control box, in the lift basket. Find the battery charger on the base of the lift on the right side. Normally, older models will have the charger mounted on the rear of the lift.
The AC extension cord must next be plugged into the charger. Be certain to charge in a well ventilated place and plug the 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 excess length were to drop out of the battery charger storage area while in use, extreme danger could likely happen.
Some of the most remarkable structures throughout the world are built using cranes. The newer cranes are utilized to be able to reach higher heights. Tower cranes provide the means to lift and move materials, tools and building parts around a construction site. There are a few different components which assemble a tower crane once they are put together. Putting a tower crane together utilizes various pieces of construction machinery.
Base
Typically, the base of a tower crane is made from a steel unit. The base is connected to a custom-designed concrete pad. This type of set-up gives the structure stability. Overall, the construction should be well engineered and constructed in order to operate at optimum safety.
Mast
The tower crane's mast provides the machine with its overall height. The mast is constructed out of individual steel sections that are connected together. The amount of sections determines the crane's height. Usually, a tower crane has a design that enables the mast to grow during construction by adding more parts as the building process continues. This way the height of the crane could be specified, ensuring it has adequate height to perform the needed work efficiently and safely.
Slewing Unit/Top Climber
A slewing unit is located above the mast. This unit houses the equipment and the motor which enables the crane to rotate. A top climber is the piece of machinery which enables the mast to grow. The top climber sits just beneath the slewing unit. Hydraulic rams inside the top climber enable the slewing unit to be disconnected 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 parts which are connected together, extending out from the top of the slewing unit and parallel to the ground. There is a trolley connected to the underside that can run the length of the boom. This particular trolley holds the hoisting mechanism.
