There is a great ease when utilizing a scissor lift, because the ease of working and the lift basket's security gives peace of mind while trying to perform tasks which could have otherwise required using the rung of a ladder. The safety risks involved with this equipment make it the best alternative for performing jobs from heights.
Nearly all scissor lifts are powered electrically by batteries that have been mounted directly onto the machine. These batteries would need to be charged after a long shift or after sitting for extended periods without use. It is a simple task to charge the batteries. This could be carried out without any particular equipment or tools and requires no heavy labor.
The equipment needs to be parked near an electrical output so as to prepare the scissor lift for charging. This charging place must also be in a well-ventilated place. Then, 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 big red button located near the charger or the control box, in the lift basket. Find the battery charger on the right side of the base of the lift. Usually, older units will 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 place 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 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 potentially take place.
Tower cranes enable the construction industry to build some wonderful structures. These cranes have been used to reach ever-increasing heights. Tower cranes provide the means to lift and transport tools, building parts and supplies around a construction site. There are various parts that assemble a tower crane once they are put together. Putting a tower crane together uses different pieces of construction equipment.
Base
The tower crane base is typically made from a steel unit. The units' base attaches to a custom pad made of concrete. This set-up provides the structure with stability. Overall, the construction must be engineered and built well in order to operate at optimum safety.
Mast
The tower cranes mast provides height to the equipment. The mast is made of connected steel sections. The amount of parts determines the height of the crane. Normally, a tower crane has a design which allows the mast to grow during construction by adding more sections as the building process goes on. This way the height of the crane can be specified, ensuring it has adequate height to efficiently and safely perform the needed work.
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 equipment that enables the mast to grow. The top climber sits just below the slewing unit. Hydraulic rams inside the top climber enable the slewing unit to be detached 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 separate steel parts that are connected together, extending out from the top of the slewing unit and parallel to the ground. There is a trolley connected to the underside that could extend the length of the boom. This particular trolley holds the hoisting device.
