Selecting between a 1.2t–4t small spider crane and a 5t–16t heavy spider crane should be based on site access, floor load limits, required lifting height, working radius, and the type of lifting work involved. Onchtech matches spider crane capacity and machine dimensions to the practical conditions of each project.
Small spider cranes in the 1.2t–4t range are suitable for residential projects, indoor glass installation, and floor areas with load-bearing restrictions. Their compact dimensions support access where conventional lifting equipment may be difficult to position.
Heavy spider cranes in the 5t–16t range are designed for projects that require greater lifting height, a larger working radius, and higher lifting capability. They are appropriate for multi-story curtain wall installation, rooftop steel structure work, and heavy industrial plant maintenance.
Select a compact 1.2t–4t model when doorway access, elevator transport, and floor loading are the primary constraints. Select a 5t–16t model when the project requires increased lifting height, working radius, and capacity. As an engineering machinery manufacturer serving B2B customers, Onchtech supports capacity and dimension matching according to site conditions and lifting requirements.
