There is a great ease when utilizing a scissor lift, because the convenience of working and the lift basket's security provides peace of mind when attempting to carry out tasks which would have otherwise needed working off the step of a ladder. The safety risks involved with this machinery make it the best alternative for completing tasks from heights.
The majority of scissor lifts are operated by batteries that are internally mounted inside 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 a simple task to charge the batteries. This can be done without any particular equipment or tools and needs no heavy labor.
So as to prepare the scissor lift for charging, position the equipment near an electrical outlet. Make sure you are doing this in a well-ventilated place. After that, so as 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 large red button located in the lift basket, near the control box or the charger. Find the battery charger on the base of the lift on the right side. Usually, older units will have the charger mounted on the rear of the lift.
The AC extension cord should next be plugged into the charger. Be certain to charge in a well ventilated area and plug the cord into an electrical outlet. So as 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 potentially take place.
Tower cranes allow the construction industry to build various incredible structures. These cranes have been designed to reach ever-increasing heights. Tower cranes offer the means to raise and move tools, building parts and materials all around a construction site. There are various parts which assemble a tower crane when they are put together. Putting a tower crane together utilizes different pieces of construction equipment.
Base
The tower crane base is typically made from a steel unit. The base of the unit connects to a custom pad made of concrete. This set-up gives the structure stability. Generally, the construction must be engineered and built well so as to operate at optimum safety.
Mast
The tower crane's mast provides the machine with its overall height. The mast is built out of individual steel parts that are connected together. The amount of sections determines the height of the crane. Normally, a tower crane has a design which enables the mast to grow during construction by adding more parts as the building process continues. This way the height of the crane can be specified, ensuring it has sufficient height to efficiently and safely carry out the needed work.
Slewing Unit/Top Climber
Over the mast is the slewing unit. It houses the motor and machines which allows the crane to rotate. A top climber is the piece of equipment which enables the mast to grow. The top climber is situated just underneath the slewing unit. Hydraulic rams inside the top climber allow the slewing unit to be disconnected from the mast by raising it higher.
Boom
"Boom" is a term that specifically refers to the working arm of a tower crane. The boom is made of steel sections connected together, which extend out from the top of the slewing unit, parallel to the ground. There is a trolley attached to the base which can extend the length of the boom. This trolley has the hoisting device.
