A lot of individuals appreciate the ease of using a scissor lift. The convenience of working and the security \offered from the lift's basket provide a lot more piece of mind than trying to carry out a similar job using the rung of a ladder. The safety risks involved with this machine make it the best choice for completing jobs from heights.
Nearly all scissor lifts are operated by batteries which are internally mounted inside the base of the lift. These batteries need to be charged after a long shift or due to sitting after extended periods without use. It is a simple job to charge the batteries. This can be carried out without any particular tools or equipment and requires no heavy labor.
In order 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 place. 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 found in the lift basket, near the charger or the control box. Find the battery charger on the right side of the base of the lift. Often, models that are older 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 place and plug the cord into an electrical outlet. So as 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 could potentially take place.
Tower cranes allow the construction industry to build various wonderful structures. These cranes have been designed to reach ever-increasing heights. Tower cranes offer the means to transport and raise supplies, tools and building parts around a construction location. There are various parts which assemble a tower crane once they are put together. Putting a tower crane together uses various pieces of construction machines.
Base
Normally, the tower crane base is made from a steel unit. The base is connected to a custom-designed concrete pad. This type of set-up gives the structure stability. Generally, the construction must be well engineered and constructed so as 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 sections determines the crane's height. Usually, a tower crane has a design that allows the mast to grow during construction by adding more parts as the building process goes on. This way the crane's height can be specified, making sure that it has enough height to safely and efficiently carry out the needed work.
Slewing Unit/Top Climber
Over the mast is the slewing unit. It houses the motor and equipment which enables the crane to rotate. A top climber is the piece of equipment that allows the mast to grow. The top climber is located just beneath the slewing unit. Hydraulic rams in 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 base that could run the length of the boom. This trolley has the hoisting device.
