There is a great convenience when using a scissor lift, since the convenience of working and the lift basket's security provides peace of mind while attempting to perform tasks which could have otherwise needed utilizing the rung of a ladder. The safety risks involved with this machine make it the right alternative for completing jobs from heights.
Nearly all scissor lifts are powered electrically by batteries which have been mounted directly onto the machinery. These batteries will have to be charged following 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 requires 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. Next, in order 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 inside the lift basket, near the control box or the charger. Find the battery charger on the right side of the base of the lift. Usually, older models will have the charger mounted on the rear of the lift.
Next, plug the charger into the AC extension cord. Be certain you are charging in an area that is well ventilated and next 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 intentionally 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 occur.
Tower cranes allow the construction industry to make several wonderful structures. These cranes have been utilized to reach ever-increasing heights. Tower cranes offer the means to lift and transport building parts, materials and tools all 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 different pieces of construction machines.
Base
The tower crane base is normally made from a steel unit. The base of the unit connects to a custom pad made of concrete. This kind of set-up gives the structure stability. Overall, the construction must be well engineered and constructed so as to operate at optimum safety.
Mast
The tower crane's mast provides the machinery with its overall height. The mast is constructed out of separate steel sections that are connected together. The amount of sections determines the crane's height. Usually, a tower crane has a design that allows the mast to grow during construction by adding further sections as the building process continues. This way the crane's height could be specified, ensuring it has enough height to perform the needed work safely and efficiently.
Slewing Unit/Top Climber
A slewing unit is situated above the mast. This unit houses the machinery and the motor which enables the crane to rotate. A top climber is the piece of machinery that allows the mast to grow. The top climber is located 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.
Boom
"Boom" is a term which particularly refers to the tower crane's working arm. The boom is made of steel sections connected together, that extend out from the top of the slewing unit, parallel to the ground. There is a trolley attached to the underside that could extend the length of the boom. This particular trolley holds the hoisting device.
