General Specifications

This document provides detailed technical specifications for the 90.900 boom crane, including dimensions, reach capabilities, operating pressures, weights, and hydraulic parameters.

Dimensions

• American/Brazilian boom line dimensions vary between 19.3 m to 36.5 m depending on configuration.
• Specific dimension sets include: 23.6 m / 36.5 m, 19.3 m / 32.8 m, 23.6 m / 34.6 m, and 19.3 m / 30.9 m.

Reach Capabilities

• Maximum manual vertical reach: 8.4 m
• Maximum manual horizontal reach: Values vary with configuration; fly jib reach extends vertical and horizontal reach.
• Hydraulic vertical and horizontal reach are specified, including with fly jib (8H0M configuration).
• Boom elevation angle: 0° to 80° continuous adjustment.
• Slewing angle: 360° rotation capability.

Operating Parameters

• Maximum operating pressure: 300 bar
• Slewing torque: 14.0 tf.m (ton-force meter)
• Hydraulic oil tank capacity: 250 liters

Weights and Installation

• Base machine weight (8H0M configuration): 7,670 kg
• Weight with fly jib: 8,930 kg
• Minimum gross vehicle weight (GVW) for installation: 27,000 kg (subject to vehicle integration study)
• Fitting space required for operation: 1.8 m

Stabilizers

• Standard equipment includes automatic articulated outriggers (patolas articuladas automáticas).
• Front stabilizer spread dimensions are provided but not explicitly detailed in the summary.

Performance Data and Load Chart Summary

The document includes detailed load charts correlating lifting capacity (kgf) with boom extension length (m) and operating angles. Key points include:

• Maximum reach extends up to 36.5 m with fly jib.
• Lifting capacities decrease as boom extension increases, with specific values such as 2100 kg at 19.3 m, 750 kg at 25.5 m, and 350 kg at 26.8 m.
• Load capacities are provided at various boom lengths and angles, indicating safe operating limits.

Key Recommendations and Notes

• Vehicle integration study is mandatory to confirm installation feasibility and minimum GVW requirements.
• Continuous boom elevation and full 360° slewing allow flexible operation.
• Automatic articulated outriggers enhance stability during operation.

Summary

This technical document comprehensively details the 90.900 boom crane's dimensions, hydraulic and mechanical specifications, operational limits, and installation requirements. It is intended for engineers and operators to ensure safe and efficient use, emphasizing the importance of vehicle integration studies and adherence to specified load capacities and operating pressures.
