There is a great convenience when using a scissor lift, since the ease of working and the lift basket's security provides peace of mind when attempting to perform tasks which would have otherwise needed using the rung of a ladder. The safety risks involved with this particular equipment make it the best alternative for completing tasks from heights.
Nearly all scissor lifts are powered electrically by batteries that have been mounted directly onto the equipment. These batteries would need to be charged following a long shift or after sitting for extended periods without use. It is a simple job to charge the batteries. This could be done without any particular tools or equipment and requires no heavy labor.
In order to prepare the scissor lift for charging, position the machine near an electrical outlet. Make sure you are doing this in a well-ventilated place. 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 found near the control box or the charger, inside the basket of the lift. Find the battery charger on the right side of the base of the lift. Usually, units which are older would have the charger mounted on the back of the lift.
Then, plug the charger into the AC extension cord. Be certain you are charging in a place which is well ventilated and next 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 can likely take place.
Several of the most wonderful structures throughout the globe are built with cranes. The newer cranes are used in order to reach higher heights. Tower cranes provide the means to lift and transport tools, building parts and materials all over a construction site. There are several different parts that assemble a tower crane when they are put together. Putting a tower crane together utilizes different pieces of construction equipment.
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 set-up gives the structure stability. Overall, the construction should 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 separate steel sections which are connected together. The amount of sections determines the height of the crane. Usually, a tower crane has a design that enables the mast to grow during construction by adding further sections as the building process continues. This way the crane's height can be specified, ensuring it has adequate height to safely and efficiently carry out the required work.
Slewing Unit/Top Climber
A slewing unit is located at the top of the mast. This unit houses the equipment and the motor that enables the crane to rotate. A top climber is the piece of machine that allows the mast to grow. The top climber sits just beneath the slewing unit. Hydraulic rams in the top climber enable the slewing unit to be detached from the mast by raising it higher.
Boom
The term "boom", refers to the working arm of a tower crane. 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 bottom which could extend the length of the boom. This trolley holds the hoisting mechanism.
