Cranes have maximum lifting heights of 300 meters and a working radius of up to 70 meters and have been providing lifting and rigging alternatives, rigging maintenance service, and lifting and rigging coaching for all types of industries for over 65 years get the best ones at atower crane rental.
The cranes seen along city skylines are tower cranes, which are used to construct tall structures like skyscrapers. A vertical tower, also known as a mast, and an outstretched jib are the components of a tower crane.
The trolley and hook block travel around the mast on the jib, which rotates 360 degrees. Small, mobile cranes are frequently used to assemble these cranes.
Hammerhead Tower Crane
The jib on a hammerhead tower crane rotates horizontally 360 degrees around the mast at a fixed level, resembling an upside-down L.
Racking is a function distinctive to this type of tower crane, in which the trolley shifts the load laterally along the jib without changing its level.
Luffing Tower Cranes
Its design is similar to that of a hammerhead tower crane, except the jib is latticed and can be elevated and lowered in a motion known as luffing.
These cranes can move their jibs more easily:
- Cranes with a larger capacity than hammerhead cranes
- Because of their smaller slewing radius ideal for working in congested areas with multiple cranes.
Self-Erecting Tower Cranes (SETC)
Self-erecting tower cranes have a horizontal jib and a ballast-mounted mast that can fold and unfold for on-site dismantling and erection. SETCs are less expensive than hammerhead or luffing tower cranes:
- Have a lighter frame
- Are transportable
- Have a much lower max load capacity
SETCs are most applicable to circumstances where:
- Construction requires a tight fit between buildings
- Extremely heavy lifts are not required
- The equipment is transported.
The crane should have a durable plate bearing the manufacturer’s name, machine model, serial number, year of manufacture, and weight for identification purposes while checking for a tower crane rental. Tower cranes fixed on construction sites. Tower cranes are used on construction sites to lift steel, concrete, acetylene torch and distributed generation, and other building materials. Tower cranes are used to move and lift heavy loads from one location to another.
