Overview

This document provides technical specifications and data for the Standard Single H Beam Girder Underslung Crane with Electrical Chain Hoist PRS1. It includes detailed parameters related to capacity, dimensions, static loads, and deadweight for various crane configurations.

1. Technical Specifications

• Crane Type: Single H beam girder underslung crane equipped with an electrical chain hoist.
• Capacity Range: From 0.5 tons up to 3.2 tons.
• Span (S): Fixed at 6 meters.
• Lifting Height (HL): Variable between 3 to 8 meters.
• Lifting Speeds (VL): Multiple speed options depending on configuration.
• Power (Pkw): Ranges from 0.36 kW to 3.1 kW depending on capacity.
• Dimensions: Includes detailed measurements such as hoist headroom (HP), total beam height (LP), girder overall height (GOH), wheelbase (WB), and end carriage overall length (OL).

2. Load Reactions and Weights

The document tabulates static load reactions and deadweight values for each capacity and configuration, including:

• Vertical Load (VLMax, VLMini): Maximum and minimum vertical reactions on wheels.
• Transversal Load (TL): Load due to crab movement.
• Horizontal Load (HL): Load due to bridge braking.
• Deadweight: Total weight of the crane without load, varying with capacity.

3. Key Parameters and Definitions

The document defines several critical parameters used in the tables:

• Force (P): Load or capacity.
• HL: Lifting height.
• VL: Lifting speed.
• Pkw: Power rating.
• HP: Hoist headroom.
• LP: Total beam height.
• S: Span.
• AD1, AD2: Approach dimensions for power supply and opposite side.
• G1: Minimum free width.
• E: Wheel to girder center distance.
• HT: Overall length of the girder.
• RVMaxi, RVMini: Maximum and minimum vertical reactions.
• RT: Transversal reaction due to crab movement.
• RH: Horizontal reaction due to braking.

4. Notes and Disclaimers

The data provided are not contractual and may be modified without prior notice by ADC. The characteristics of the crane materials and components can be updated, so users should verify the latest specifications before use.

5. Summary Table Insights

The tables present a comprehensive matrix of crane capacities against various parameters such as power, dimensions, and load reactions. For example:

• At 0.5 t capacity, power ranges from 0.36 kW to 0.72 kW with deadweight around 810 kg.
• At 3.2 t capacity, power reaches up to 2.42 kW with deadweight exceeding 1483 kg.
• Load reactions increase proportionally with capacity, affecting design considerations for supporting structures.

Critical Recommendations and Best Practices

• Ensure selection of crane capacity matches the required lifting height and speed for operational efficiency.
• Consider static load reactions carefully in the design of supporting infrastructure to avoid structural failures.
• Verify the latest technical data from ADC before procurement or installation due to possible updates.
• Account for approach dimensions and clearances (AD1, AD2, G1) to ensure safe and unobstructed crane operation.
