How to Transport Prefabricated Concrete Houses

The transportation of prefabricated concrete houses requires scientific planning and standardized operations, covering three core aspects: pre-transportation preparation, transportation process control, and detailed management.

I. Pre-Transportation Preparation

1. Disassembly and Packaging:
   The house components (such as walls, roofs, and frames) should be disassembled and categorized, with assembly sequences marked. Fragile components (such as doors and windows) should be packaged separately, wrapped in foam or soft materials to prevent collision damage during transportation.
2. Selection of Transportation Vehicles:
   Choose appropriate vehicles based on the size and weight of the components. For example, prefabricated beams exceeding 12 meters in length or large-sized wall panels require low-bed trailers or specialized frame vehicles, which have higher requirements for turning radius and road width, necessitating prior evaluation of traffic conditions.

II. Transportation Process Control

1. Loading and Securing:
   Components should be arranged in sequence to maintain vehicle balance, and firmly secured using steel straps, ropes, or tie-downs. Unsecured components are prone to shifting and colliding during bumps or sharp turns, leading to edge damage or even structural damage, so a standardized securing plan and the use of cushioning materials are necessary.
2. Route Planning:
   • Road Conditions: Comprehensive consideration should be given to factors such as height restrictions, bridge load-bearing capacity, and traffic control. For example, in large cities like Guangzhou, it is necessary to avoid restricted areas during peak hours in the morning and evening, and narrow streets or old urban areas require prior inspection or simulation of passage.
   • Road Conditions and Speed: Prioritize main roads and expressways, avoiding rough or congested routes. It is recommended to maintain a speed not exceeding 60 kilometers per hour to avoid sudden braking or sharp turns.
3. Weather and Escort:
   Transportation should be suspended in adverse weather conditions (such as heavy rain or strong winds), and dedicated personnel should be arranged to escort the cargo, checking its condition in real-time and addressing any issues promptly.

III. Detailed Management

1. Moisture Prevention Measures:
   Concrete components are susceptible to moisture, so they should be covered with waterproof cloth during transportation to prevent rain erosion and a consequent decrease in strength.
2. Legal Compliance:
   For oversized or over-height transportation, relevant procedures should be completed in advance to avoid penalties or delays due to non-compliance.
3. Construction Site Coordination:
   The transportation route should be communicated with the construction party to clarify the unloading area size, foundation bearing capacity, and crane turning space. For example, prefabricated stairs and composite slabs require tower crane assistance. If the unloading point is too far from the lifting point, secondary transportation may be necessary, increasing costs and the risk of damage. Coordinating the transportation route with the construction plan can enhance overall efficiency.
