Numerous people value the convenience of using a scissor lift. The convenience of working and the safety \offered from the lift's basket provide much more piece of mind than trying to carry out a similar job using the rung of a ladder. The safety risks involved with this equipment make it the best option for carrying jobs from heights.
The majority of scissor lifts are powered electrically by batteries that have been mounted directly onto the machinery. These batteries would need to be charged after 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 specialized equipment or tools and needs no heavy labor.
The machinery needs to be parked next to an electrical output so as to prepare the scissor lift for charging. This charging area should also be in a well-ventilated area. Next, 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 found in the lift basket, near the control box or the charger. Find the battery charger on the base of the lift on the right side. Usually, older models will have the charger mounted on the rear of the lift.
The AC extension cord must next be plugged into the charger. Be sure 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 intentionally 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 happen.
Tower cranes enable the construction industry to build various incredible structures. These cranes have been designed to reach ever-increasing heights. Tower cranes provide the way to move and raise tools, building parts and supplies all around a construction location. There are a few different parts that assemble a tower crane once they are put together. Putting a tower crane together utilizes various pieces of construction machines.
Base
Typically, the tower crane base is made from a steel unit. The base is attached to a concrete pad that is custom-designed. This set-up provides the structure with stability. Overall, the construction should be well engineered and constructed so as to operate at optimum safety.
Mast
The mast on the tower crane provides the machinery with its overall height. The mast is constructed out of separate steel sections which are connected together. The amount of parts determines the crane's height. 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 crane's height could be specified, ensuring it has sufficient height to carry out the required work efficiently and safely.
Slewing Unit/Top Climber
Over the mast is the slewing unit. It houses the motor and machines that enables the crane to rotate. A top climber is the piece of machine which enables the mast to grow. The top climber sits just below the slewing unit. Hydraulic rams in the top climber allow the slewing unit to be detached from the mast by raising it higher.
Boom
"Boom" is a term that specifically refers to the tower crane's working arm. The boom is made of steel parts attached together, that extend out from the top of the slewing unit, parallel to the ground. There is a trolley connected to the underside which can extend the length of the boom. This particular trolley holds the hoisting device.
