Lifting
Lifting mode lets you analyze lifting and manual load-handling tasks with Ergoniza Intelligent.
This mode is intended for situations in which a person lifts, lowers, or moves a load between an origin and a destination. Unlike Single posture and Multiple postures modes, Lifting mode focuses the assessment on manual-handling parameters such as load weight, lifting frequency, the activity’s temporal organization, coupling quality, and the geometric conditions at the origin and destination.
Purpose of Lifting mode
The primary purpose of this mode is to estimate the risk associated with a lifting task using the Recommended Weight Limit and Lifting Index.
The system lets you define:
- the general conditions of the lifting activity;
- one or more lifting tasks;
- the specific parameters of each task;
- one or more lifting periods and the recovery periods between them;
- the temporal blocks used to assess the activity;
- the model posture at the origin and destination;
- the load coupling;
- lifting frequency and load weight;
- individual and overall analysis results.
Lifting mode supports both single-task analyses, when there is only one lifting task, and multitask analyses, when the activity contains several tasks with different conditions.
A lifting task describes one specific handling condition: load, frequency, coupling, origin, and destination. A lifting period describes how long tasks are performed before recovery. An assessment can therefore contain one or more tasks and, independently, one or more periods.
Ergoniza Intelligent groups periods into assessment blocks according to their duration and the recovery between them. All blocks are assessed and their results compared. The block with the least favorable index is identified as the determining block, and its index is used as the representative overall result. Results from other blocks are retained for review and are neither added nor averaged. If several blocks reach the same maximum result, all are considered determining blocks.
General procedure
Work in Lifting mode usually follows this sequence:
- Select Lifting mode at the top of the interface.
- Define the temporal organization of lifting—one period, a regular pattern, or a custom sequence—together with its durations and recovery periods, the load constant, and the anthropometric adjustment.
- Create one or more lifting tasks.
- Select the task to configure.
- Define its task-specific settings, such as name, frequency, load weight, and coupling quality.
- Define the lifting origin posture.
- Define the lifting destination posture.
- Review the temporal summary, assessment blocks, and determining block, confirming that no block accumulates more than eight hours of lifting and that the sequence’s total elapsed time—lifting plus recovery—does not exceed eight hours.
- Review the individual and overall results of the load-lifting analysis.
