Pillar Jib Crane Foundation Installation Methods and Technical Guide

A pillar jib crane is a freestanding lifting device widely used in workshops, warehouses, and production lines for material handling. To ensure safe operation and long-term stability, the foundation of a pillar jib crane is one of the most critical components in the entire system. A well-designed and properly installed foundation not only supports the crane's load but also resists tilting, vibration, and ground stress over time.

In this article, we’ll explore everything you need to know about pillar jib crane foundations, including concrete foundation, design, and installation methods. If you're planning to install a pillar jib crane, keep reading to ensure your foundation meets safety and efficiency standards.

Jib Crane Foundation Design

Generally, the base is designed using finite element analysis (FEA) or structural design software, in line with local building codes. A typical design may involve a foundation block of 800mm–1200mm depth with heavy-duty anchor bolts fixed into the rebar cage.

Pillar Jib Crane Foundation: Common Pre-Embedding Methods

The installation method of pillar jib cranes should be selected according to the type of foundation and site conditions. Mainly, there are two forms of pre-buried installation and surface fixed installation, which can be subdivided into the following five installation methods:

1. Pre-embedded bolts in concrete (most common)

Pre-embedded bolts in the concrete foundation first, when the concrete is cured, the base of the jib crane is bolted, and the verticality of the jib crane is corrected.

2. Pre-embedded specialized positioning fixture

Minimize post-installation vertical alignment adjustments by using a special positioning jig embedded in the floor bolts.

3. Large base plate on concrete floor

Secure the square base plate to the floor using chemical anchors, level, and tighten.

Then bolt the crane column to the base plate, taking care to adjust the level of the large base plate; this method is usually applied to standard concrete floors.

4. Large base plate on the concrete ceiling

Similar to the floor mounting method. Firstly, use the long threaded rod to fix the base plate on the ceiling (usually a concrete floor slab), and secondly, connect the cantilever crane column with the bolt holes on the large base plate. This method is suitable for small tonnage cranes with high ceiling strength.

5. Adjustable tongue and groove plate

For jib cranes requiring exact positioning or handling dynamic loads, an adjustable dowel system is employed. This method utilizes countersunk dowel plates with high-precision imported dowel pins to ensure secure alignment under operational stresses.

Each method has its applicability, depending on load capacity, foundation type, and installation conditions. Proper alignment and anchoring ensure stability and safety.

Jib Crane Foundation Installation Steps

Jib crane foundation installation typically follows these steps:

1. Site preparation and soil inspection.
2. Excavation according to the foundation drawing.
3. Rebar cage assembly and formwork preparation.
4. Anchor bolt positioning using a template plate.
5. Concrete pouring and vibration.
6. Curing for 7–14 days.
7. Removing the template and leveling the base.
8. Mounting the jib crane base plate after the concrete has fully cured.
9. Anchor bolts can be embedded during pouring or post-installed using chemical anchors if retrofitting.

How to Install a 1-Ton Jib Crane Foundation?

For a 1-ton pillar jib crane, a common foundation configuration might include:

• Foundation diameter: 1200mm
• Foundation depth: 900mm
• Anchor bolts: M24 x 800mm, 8 pieces in a circle
• Concrete: C30-grade with steel rebar cage
• Rebar: 12mm diameter bars, spaced at 150mm intervals
• Rotation range: 270 degrees
• Curing time: 10 days minimum before installation
• After curing, the crane base is installed using a torque wrench to tighten bolts to the specified tension.
