There is a great ease when using a scissor lift, since the convenience of working and the lift basket's safety gives peace of mind while trying to carry out tasks which would have otherwise needed using the rung of a ladder. The safety risks involved with this equipment make it the best alternative for performing tasks from heights.
The majority of scissor lifts are powered electrically by batteries which have been mounted directly onto the equipment. These batteries would have to be charged following a long shift or after sitting for extended periods without use. It is a simple task to charge the batteries. This can be done without any specialized equipment or tools and requires no heavy labor.
The machine needs to be positioned near an electrical output in order to prepare the scissor lift for charging. This charging area must also be 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 located inside the basket of the lift, near the control box or the charger. Find the battery charger on the base of the lift on the right side. Often, older units would 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 when in use, extreme danger could likely take place.
Tower cranes allow the construction industry to build several amazing structures. These cranes have been designed to reach ever-increasing heights. Tower cranes offer the means to raise and transport tools, building parts and supplies all around a construction site. There are a few different parts which assemble a tower crane when they are put together. Putting a tower crane together uses different pieces of construction machines.
Base
Usually, the base of a tower crane is made from a steel unit. The base is attached to a concrete pad that is custom-designed. This set-up gives the structure stability. Overall, the construction has to be well engineered and built so as to operate at optimum safety.
Mast
The tower crane's mast provides the equipment with its overall height. The mast is constructed out of individual steel sections which are connected together. The amount of parts determines the height of the crane. Typically, a tower crane has a design which allows the mast to grow during construction by adding further parts as the building process goes on. This way the height of the crane could be specified, ensuring it has adequate height to perform 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 that allows the crane to rotate. A top climber is the piece of equipment which allows the mast to grow. The top climber sits 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
The term "boom", refers to the tower crane's working arm. The boom is made up of individual steel sections that are attached together, extending out from the top of the slewing unit and parallel to the ground. There is a trolley attached to the bottom that can extend the length of the boom. This trolley holds the hoisting mechanism.
