Overview

This document provides detailed technical specifications, component descriptions, and dimensional data for crane components, focusing on end carriages, wheels, gearboxes, and electrical components used in single and double girder cranes, including underslung and gantry crane configurations.

1. Crane Components and End Carriages

The document lists various end carriage models identified by wheel diameters (e.g., Ø125-VB1, Ø160-VB2, Ø250-VC, Ø315-VC, Ø400-VD, Ø500-VD/VE) and their corresponding capacities and dimensions. It distinguishes between single girder and double girder cranes, providing wheel base measurements, spans, and capacities in tonnes (Tn).

Key parameters include wheel diameter, wheel base, span, and capacity. End carriages are available in welded (S), articulated (A), single girder (M), and double girder (B) types. Dimensions such as L1, L2, L3, L4, e1, e2, B, H1, H2, and H are specified for each model, critical for installation and compatibility.

2. Wheel Selection and Specifications

The wheel selection chart provides guidance on choosing wheels based on span, wheel base, and capacity. Wheel diameters range from 125 mm to 630 mm, with corresponding load capacities and speeds. Wheels feature double flanges and mounted bearings, designed for smooth acceleration and braking with minimal noise.

Wheel heads for gantry cranes are detailed with maximum admissible wheel loads according to FEM/UNE M4 standards, considering rail width and quality (minimum S355 steel). Different rail types such as Burbach, curved, and square rails are referenced with dimensional formulas.

3. Gearboxes and Motor Specifications

The document describes three-stage and four-stage motor-gearboxes specially designed for cross travel and long travel motions. Gearboxes are directly connected to wheels via splined shafts, ensuring gradual acceleration and smooth braking.

Motor power ratings range from 0.4 kW to 7.5 kW, with various motor types and gearbox models (e.g., VB1-60, VB2-60, VC-85, VD-110, VE-110). Weight and dimensional data for gearboxes and motors are provided, essential for integration into crane systems.

4. End Carriage Dimensions and Weights

Detailed tables list dimensions (A1, A2, A3, A4, A5, A7, A8, etc.) and weights for end carriages across different models and girder types. Minimum dimensions and base measurements (dimension B) are highlighted, along with trolley span (dimension A14).

Weights vary significantly depending on the model and configuration, with separate data for single and double girder cranes. This information is critical for structural design and load calculations.

5. Electrical Components and Accessories

The document enumerates electrical components and accessories integral to crane operation, including:

• Hoist limit switch
• Load limit device
• Pendant plug-in connector
• Cross travel and long travel limit switches and actuators
• Supports for power feed systems and cable protection
• Motor plug-in connectors
• Towing arm and cable trolleys
• Remote control and control cabinets (hoist and long travel)
• Structural supports such as girder and profile supports, ladder support

These components ensure safe and efficient crane operation, with emphasis on limit controls and power management.

6. Boogies and Wheel Heads for Gantry Cranes

Specifications for boogies with wheel diameters ranging from 315 mm to 630 mm are provided, including weight, span, and admissible wheel loads. Weld-on wheel heads are detailed with dimensions and load capacities, designed for various rail widths and types.

The document includes dimensional data for wheel heads and boogies, supporting selection and maintenance of gantry crane components.

Critical Information and Best Practices

• Wheel diameter selection depends on speed, duty cycle, and rail width; final diameter must be confirmed accordingly.
• End carriages with dimension A1 less than 2100 mm are supplied as loose items, indicating special handling or installation requirements.
• Load capacities and wheel loads comply with FEM/UNE M4 standards, ensuring safety and reliability.
• Motor-gearbox assemblies are designed for smooth operation with minimal noise and gradual acceleration.
• Electrical components include multiple limit switches and safety devices to prevent over-travel and overload conditions.

Conclusion

This technical document serves as a comprehensive reference for selecting, specifying, and installing crane components, particularly end carriages, wheels, gearboxes, and electrical systems. It provides essential dimensional data, load capacities, and operational parameters to ensure compatibility, safety, and performance in crane applications.
