There is a great ease when using a scissor lift, since the convenience of working and the lift basket's security provides peace of mind when attempting to carry out tasks that would have otherwise required utilizing the rung of a ladder. The safety risks involved with this machine make it the best alternative for carrying jobs from heights.
Nearly all scissor lifts are powered electrically by batteries that 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 could be done without any specialized tools or equipment and requires no heavy labor.
In order to prepare the scissor lift for charging, position the equipment next to an electrical outlet. Make sure you are doing this in a well-ventilated area. After that, 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 large red button situated inside the lift basket, near the control box or the charger. Find the battery charger on the base of the lift on the right side. Normally, units which are older will have the charger mounted on the back of the lift.
Next, plug the charger into the AC extension cord. Be certain you are charging in a place that is well ventilated and then plug the extension cord into an electrical outlet. In order to avoid 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 while in use, extreme danger could likely happen.
Tower cranes enable the construction industry to make several wonderful structures. These cranes have been designed to reach ever-increasing heights. Tower cranes provide the means to lift and transport building parts, supplies and tools around a construction location. 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 machines.
Base
Usually, the base of a tower crane is made from a steel unit. The base is connected to a custom-designed concrete pad. 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 mast on the tower crane provides the equipment with its overall height. The mast is built out of separate steel parts that are connected together. The amount of sections determines the height of the crane. Usually, a tower crane has a design which allows 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 carry out the required work efficiently and safely.
Slewing Unit/Top Climber
A slewing unit is located at the top of the mast. This unit houses the machinery and the motor which allows the crane to rotate. A top climber is the piece of equipment which enables 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.
Boom
"Boom" is a term that particularly refers to the tower crane's working arm. The boom is made of steel sections attached together, which extend out from the top of the slewing unit, parallel to the ground. There is a trolley connected to the bottom that can run the length of the boom. This trolley holds the hoisting device.
