How to Unload Container Houses

The unloading of container houses mainly relies on large machinery for lifting operations, and it is necessary to select appropriate lifting equipment according to site conditions and follow safety regulations.

I. Common Unloading Equipment and Scenarios

1. Container Gantry Cranes
   Suitable for hardened ground scenarios such as inland dry ports and storage yards, they can operate directly in multi-level stacking areas. Their lifting, traveling, and traversing movements are controllable, enabling precise positioning to reduce container collisions. They also come with overload and out-of-bounds protection devices to ensure operational safety. For example, after foreign trade containers arrive at the port, gantry cranes can lift the containers from transport vehicles to designated stacking areas for classification and storage.

2. Forklift and Truck Combination
   In ordinary sites or small projects, forklifts can work in conjunction with trucks to complete unloading. For example, Beijing Ligong Moving Company provides forklift services, supporting cargo handling and the transportation of valuable items, suitable for the short-distance movement of container houses.

3. Mobile Cranes (such as truck-mounted cranes)
   Suitable for scenarios with complex ground conditions or requiring high-altitude operations. For example, for the unloading of a container house for a creative studio in the suburbs, after leveling the ground, a truck-mounted crane can be used to lift a 6-meter-long container into place, enabling quick connection to electricity and occupancy.

II. Key Points of Unloading Operations

1. Site Preparation
   Ensure that the ground is hardened and has sufficient bearing capacity to prevent lifting equipment from sinking or tilting. In scenarios such as dry ports, it is necessary to plan stacking areas in advance to save land resources.

2. Equipment Selection
   Select equipment according to the size and weight of the container house. For example, a 20-foot container has a load capacity of 25 tons, and a 40-foot container has a load capacity of 45 tons. Corresponding lifting capacity gantry cranes or truck-mounted cranes need to be matched.

3. Safety Protection
   Check key components of lifting equipment such as braking systems and steel wires to ensure there are no risks of overloading or out-of-bounds operations. During operations, designate warning areas to prevent personnel from entering dangerous zones.

III. Handling of Special Scenarios

1. Multi-level Stacked Containers
   Unloading should be carried out in order from the upper level to the lower level to avoid tipping due to a shift in the center of gravity. Gantry cranes can achieve efficient operations through their multi-level stacking functions.

2. Unloading for Temporary Projects
   For scenarios such as temporary dormitories and office areas on construction sites, modular design products such as packing-box container houses can be used. Their frames are made of hot-dip galvanized cold-formed steel, supporting multiple disassemblies and assemblies. After unloading, they can be directly transported to new sites for reassembly.
