Liebherr Ltm 1400 7.1 Crane Load Chart
Introduction
The Liebherr LTM 1400 7.1 crane is a powerful machine that can lift heavy loads with ease. It has a maximum lifting capacity of 400 tons and can reach a height of up to 122 meters. This crane is used in a variety of industries, including construction, mining, and oil and gas. One important aspect of using this crane is understanding the load chart.
What is a Load Chart?
A load chart is a graph that shows the maximum weight that a crane can lift at different boom lengths and radii. It is important to refer to the load chart when planning a lift to ensure that the crane is not overloaded and that it is being used safely and efficiently.
Understanding the Liebherr LTM 1400 7.1 Load Chart
The Liebherr LTM 1400 7.1 load chart is divided into several sections, each of which provides information about the crane's capacity at different boom lengths and radii. The load chart includes the following:
- Boom length
- Radius
- Counterweight
- Maximum load capacity
By referring to the load chart, the operator can determine the maximum weight that the crane can lift at a specific boom length and radius. This information is critical for ensuring that the crane is not overloaded and that the lift is performed safely.
Factors Affecting the Load Capacity
Several factors can affect the load capacity of the crane, including:
- Boom length
- Radius
- Counterweight
- Wind speed and direction
- Ground conditions
- Slope of the ground
- Temperature
- Altitude
It is important to consider these factors when planning a lift and to refer to the load chart to ensure that the crane is being used safely and efficiently.
Using the Load Chart
Using the load chart is a straightforward process. To determine the maximum weight that the crane can lift at a specific boom length and radius, follow these steps:
- Find the boom length on the load chart.
- Find the radius on the load chart.
- Determine the counterweight required for the lift.
- Read the maximum load capacity at the intersection of the boom length and radius.
By following these steps, the operator can ensure that the crane is being used safely and efficiently.
Conclusion
The Liebherr LTM 1400 7.1 crane is a powerful machine that can lift heavy loads with ease. Understanding the load chart is critical for ensuring that the crane is being used safely and efficiently. By referring to the load chart and considering the factors that can affect the load capacity, the operator can ensure that the lift is performed safely and that the crane is not overloaded.
