What Crane to Use for Prefabricated Houses

Common types of cranes used for prefabricated houses include tower cranes, derrick cranes, crawler cranes, truck cranes, and jib cranes (small cranes), with jib cranes being more prevalent in rural settings.

1. Tower Cranes

Tower cranes are one of the core pieces of equipment for lifting prefabricated houses, especially suitable for the installation of high-rise or large prefabricated components. Their advantages lie in their high lifting height and wide coverage, enabling three-dimensional space operations through rotation and luffing mechanisms. In rural settings, flat-top tower cranes have gradually become the mainstream choice due to their simplified structure and easy installation. They do not require counterweights, reducing site requirements, and have relatively low transportation and assembly costs, making them suitable for small to medium-sized prefabricated house projects.

2. Crawler Cranes

Crawler cranes are renowned for their strong stability and low ground pressure, making them suitable for operations on soft or complex terrain. Their crawler design disperses the machine's weight, reducing the risk of ground settlement, especially in rural areas with low soil bearing capacity. Additionally, crawler cranes can travel with loads, offering high flexibility, although their movement speed is relatively slow, and they require specialized transport vehicles for relocation, resulting in slightly higher costs compared to other types.

3. Truck Cranes

Truck cranes, with lifting devices mounted on the chassis of a heavy-duty truck, are characterized by their high mobility and rapid relocation. They do not require additional track laying or foundation preparation, making them suitable for short-cycle, multi-location prefabricated house projects. However, their stability is greatly affected by ground conditions, requiring reinforcement measures in windy or uneven terrain, and their lifting capacity is generally lower than that of tower and crawler cranes.

4. Jib Cranes (Small Cranes) - The Mainstream Choice in Rural Areas

In the rural self-built housing market, jib cranes have become the mainstream choice due to their compact structure, low cost, and easy installation. They are typically electrically or manually driven, with adjustable arm lengths, suitable for lifting lightweight prefabricated components (such as floor slabs and wall panels). Their advantages include:

• No complex foundation required: They can be directly fixed to buildings or independent supports, reducing construction preparation time;
• Simple operation: Farmers can master their use after short-term training, reducing labor costs;
• High cost-effectiveness: The equipment price is only 1/5 to 1/10 of that of large cranes, making them suitable for rural projects with limited budgets.

Selection Recommendations

• High-rise or large-scale projects: Prioritize the use of tower cranes or crawler cranes to ensure lifting efficiency and safety;
• Low-rise rural houses: Jib cranes are the most cost-effective choice, balancing practicality and economy;
• Complex terrain or frequent relocation: Truck cranes offer greater flexibility, but cost and demand matching should be evaluated.
