Tower Crane Load Charts: A Comprehensive Guide

When it comes to construction projects, one of the most critical pieces of equipment is the tower crane. These cranes are designed to lift heavy loads to great heights with precision and accuracy. One of the key aspects of a tower crane is its load chart, which outlines the maximum weight it can lift at different radii.

In this article, we will explore the load charts of the Raimondi LR372 luffing jib model, a 370 tonne-metre-rated crane that has recently been announced by the Italy-based manufacturer. With its impressive lifting capacity and versatile design, the LR372 is sure to be a popular choice among construction professionals.

The LR372 features a six-tonne version with a 28 kW hoist winch that can lift loads at speeds of up to 108 m/minute in partial load mode. The eight-tonne version boasts an even more impressive hoist winch, powered by a 45 kW electric motor that can reach speeds of up to 158 m/minute.

In terms of height, the LR372 can be configured to reach heights of up to 95 meters in freestanding mode, with the option to extend its basic jib to a maximum of 45 meters. The crane also features a single- or two-fall operating system, which allows for peak load capacity to be increased by an additional 250 kg.

The LR372's elevator is designed for easy inspection and maintenance, featuring front and side windows that provide clear visibility. The lift itself has a tie distance of between 4.5 and 6 meters, making assembly a breeze. With a speed of 24 meters per minute and a maximum height of 150 meters, the elevator can be easily moved between different tower sections without requiring any modifications to the mast structure.

The LR372's load capacity is impressive, with a maximum lifting capacity of 20 tonnes on two falls of rope and a radius of up to 60 meters. The crane also features an auxiliary hydraulic emergency brake as standard, providing added safety and peace of mind for operators.

In addition to its impressive lifting capacity, the LR372 also boasts a range of other features that make it an attractive choice for construction professionals. These include a luffing winch with a secondary emergency brake, rope capacity on the main drum of 880 meters, and a hoisting winch with a maximum lifting speed of 250 meters per minute.
