There is a great convenience when utilizing a scissor lift, as the ease of working and the lift basket's security gives peace of mind while attempting to carry out tasks that could have otherwise needed utilizing the step of a ladder. The safety risks involved with this machine make it the right alternative for performing tasks from heights.
Most scissor lifts are operated by batteries that are internally mounted inside the lift's base. These batteries have to be charged following a long shift or due to sitting after 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 equipment has to be positioned next to an electrical output in order to prepare the scissor lift for charging. This charging area must also be in a well-ventilated area. Then, 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 located near the charger or the control box, in the basket of the lift. Find the battery charger on the right side of the base of the lift. Often, older models would have the charger mounted on the back of the lift.
The AC extension cord should next be plugged into the charger. Be sure to charge in a well ventilated place and plug the cord into an electrical outlet. In order 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 place when in use, extreme danger can likely occur.
Tower cranes enable the construction industry to make various wonderful structures. These cranes have been utilized to reach ever-increasing heights. Tower cranes provide the way to transport and lift materials, tools and building parts all around a construction site. There are various parts that assemble a tower crane when they are put together. Putting a tower crane together uses various pieces of construction equipment.
Base
The base of a tower crane is usually made from a steel unit. The base of the unit connects to a custom pad made of concrete. This kind of set-up gives the structure stability. Generally, the construction must be engineered and built well in order to operate at optimum safety.
Mast
The tower cranes mast provides height to the machine. The mast is made of connected steel sections. The amount of parts determines the crane's height. Usually, a tower crane has a design that enables the mast to grow during construction by adding further parts as the building process continues. This way the height of the crane can be specified, making sure that it has enough height to perform the needed work safely and efficiently.
Slewing Unit/Top Climber
A slewing unit is situated above the mast. This unit houses the machines and the motor that allows the crane to rotate. A top climber is the piece of machine which allows the mast to grow. The top climber is situated 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 working arm of a tower crane. The boom is made of steel parts attached together, which extend out from the top of the slewing unit, parallel to the ground. There is a trolley attached to the base that could extend the length of the boom. This particular trolley holds the hoisting mechanism.
