Overview

The document provides detailed technical specifications, load charts, mechanical data, and operational parameters for the Potain MCT 50 tower crane model. It includes multilingual sections covering mast reactions, crane heights, weights, load capacities, and mechanism performance.

Main Sections

1. Crane Dimensions and Structural Data

• Mast heights ranging from approximately 20 m to over 58 m depending on configuration.
• Distances between collars (mast sections) specified, e.g., 1.2 m, 1.5 m, 3 m, etc.
• Crane weights in service vary with configuration, from around 1.1 t to over 24 t.

2. Load Capacities and Load Charts

• Load capacities vary with jib length and height, with maximum loads up to approximately 2.5 t at shorter radii and decreasing with increased radius.
• Load charts (MEU 3, MEU 4, ZC 2030, ZD 2030, ZE 12 A, etc.) provide detailed lifting capacities at various heights and jib lengths.
• Load curves are presented for different mast configurations and jib extensions, indicating safe working loads.

3. Mast Reactions and Forces

• Reactions in service and out of service are detailed, including horizontal reactions and vertical loads on mast sections.
• Data includes forces at different heights and configurations, important for foundation and structural design.
• Information on reactions without load, ballast, or transport axles but with maximum jib and height.

4. Mechanisms and Performance

• Hoisting speeds up to approximately 4.3 m/min.
• Power ratings for motors and drives are specified, including horsepower (hp), kilowatts (kW), and motor types (e.g., 15 LVF, 25 LVF Optima).
• Operational parameters such as trolleying, slewing, and travelling speeds are indicated.

5. Operational Notes and Safety

• Instructions emphasize consulting the corresponding technical manuals for detailed operational guidance.
• Notes on telescoping over slabs and climbing crane operations are referenced.
• Multilingual safety and operational terms are provided for international use.

Key Technical Highlights

• Maximum jib length up to approximately 41 m.
• Maximum lifting capacity around 2.5 t at close radius, decreasing with radius extension.
• Crane height without cab up to approximately 58 m depending on mast configuration.
• Horizontal reactions and mast forces critical for structural support design.
• Multiple mast section types and configurations (MEU 3, MEU 4, B 125 A, P 12 series) with corresponding load and reaction data.
• Power supply specifications: 400 V ±6% -10%, 50 Hz, complying with CEI 38 / IEC 38 standards.
