Transportation Requirements for Cement Prefabricated Houses
The transportation requirements for cement prefabricated houses cover six major aspects: roads, tools, routes, process management, documentation and qualifications, and handling of special situations. Details are as follows:
I. Road Requirements for Transportation
The transportation roads must meet several conditions: the road surface should be flat to avoid damage to the house caused by bumps or depressions; there should be no obvious obstacles (such as stones or puddles) to ensure smooth vehicle passage; the slope should be appropriate to avoid affecting stability due to excessive height or steepness; the road hardness must meet the load-bearing requirements to prevent vehicle sinking due to softness; the road should be kept clean to reduce interference from debris during transportation; the road width must accommodate the passage of the house dimensions (e.g., 6 meters × 3.3 meters); clear height and weight limit signs should be in place to avoid the passage of overloaded vehicles; safety facilities (such as markings and road signs) should be installed to ensure transportation safety.
II. Transportation Tools and Reinforcement Requirements
Specialized vehicles such as low-bed semi-trailers should be selected based on the weight (approximately 18-22 tons) and dimensions of the house to ensure matching load-bearing and size requirements. The reinforcement plan must be strictly implemented: use high-strength chains to secure the house to the vehicle, with rubber pads placed at contact points to prevent wear; install adjustable triangular wooden wedges to prevent lateral movement, with the wedges fixed to the vehicle bed using steel nails; before transportation, verify the reliability of the reinforcement, ensuring that the displacement during sudden braking is less than 2 centimeters.
III. Transportation Route Planning and Approval
Plan the route reasonably based on the house dimensions, weight, and destination, avoiding sections with height or width restrictions. If the route involves special areas such as bridges or tunnels, apply for approval from the traffic management department or road administration department; if the house dimensions or weight exceed legal limits, apply for an over-limit transportation permit.
IV. Transportation Process Management
Transportation vehicles should be equipped with 4G video surveillance equipment to transmit real-time footage to the command center and regularly report location, speed, and vehicle status; mountain road speeds should be controlled below 30 km/h, with low-gear engine braking used for continuous downhill sections; vehicles should be equipped with emergency equipment such as spare tires, jacks, and tire repair tools to handle unexpected situations.
V. Documentation and Qualification Requirements
Transportation vehicles must have legal operating qualifications (such as a vehicle license and road transportation permit), and drivers must hold corresponding category driver's licenses; a transportation contract must be signed with the shipper to clarify the rights and obligations of both parties, and cargo transportation insurance should be purchased for the house; safety transportation measures (such as cargo securing and anti-slip/anti-roll measures) and an emergency plan should be formulated; if transportation may cause dust pollution, measures such as covering with dust nets should be taken.
VI. Handling of Special Situations
If the house is considered a special item (e.g., containing hazardous components), apply for a special item transportation permit; if the transportation route crosses multiple administrative regions, coordinate and communicate with the relevant departments in each region to ensure smooth transportation.
