There is a great ease when utilizing a scissor lift, as the ease of working and the lift basket's safety provides peace of mind when trying to perform tasks which would have otherwise needed using the rung of a ladder. The safety risks involved with this machinery make it the right choice for performing tasks from heights.
Nearly all scissor lifts are powered electrically by batteries which have been mounted directly onto the equipment. These batteries will need to be charged following a long shift or after sitting for extended periods without use. It is an easy job to charge the batteries. This could be done without any particular equipment or tools and requires no heavy labor.
So as to prepare the scissor lift for charging, park the equipment next to an electrical outlet. Make sure you are doing this in a well-ventilated area. 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 situated 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. Normally, units that are older would 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 area and plug the 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 intentionally short. This is because if any excess length were to drop out of the battery charger storage place while in use, extreme danger can potentially occur.
Several of the most wonderful structures around the globe are made with cranes. The newer cranes are utilized in order to reach higher heights. Tower cranes provide the way to transport and lift tools, building parts and materials around a construction site. There are various parts that assemble a tower crane when they are put together. Putting a tower crane together utilizes different pieces of construction machines.
Base
Normally, the base of a tower crane is made from a steel unit. The base is attached to a custom-designed concrete pad. This kind of set-up provides the structure with stability. Overall, the construction should be engineered and constructed well in order to operate at optimum safety.
Mast
The mast on the tower crane provides the machinery with its overall height. The mast is built out of separate steel sections which are connected together. The amount of sections determines the crane's height. Usually, a tower crane has a design which allows the mast to grow during construction by adding more sections as the building process continues. This way the crane's height can be specified, making sure that it has adequate height to perform the required work safely and efficiently.
Slewing Unit/Top Climber
Above the mast is the slewing unit. It houses the motor and equipment that allows the crane to rotate. A top climber is the piece of machine that allows 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
The term "boom", refers to the working arm of a tower crane. The boom is made up of individual steel sections 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 that can extend the length of the boom. This particular trolley holds the hoisting mechanism.
