Latest company blog about Givens Engineering Introduces Precision Cantilever Crane Sizing

Imagine a factory floor where space utilization is maximized, material flows seamlessly, and productivity soars. This level of efficiency can often be achieved with a precisely sized, custom-designed jib crane. Givens Engineering specializes in tailored jib crane solutions for diverse industries, offering a range of dimensions to streamline material handling processes.

Renowned for its lightweight crane designs, Givens Engineering emphasizes that not all jib cranes are created equal. Selecting the correct size is critical for performance, safety, and operational efficiency. The company provides comprehensive sizing guidelines covering load capacity, hook height under boom (HUB), and boom length.

Selecting the Right Jib Crane Size

Givens Engineering recommends the following steps to ensure optimal sizing for specific applications:

1. Determine Load Capacity

Accurately assess the maximum weight the crane will handle. This primary factor ensures the selected crane’s rated capacity exceeds operational loads for safe performance.

2. Select Hook Height Under Boom (HUB)

HUB measures the vertical distance from the floor to the hook at its highest point. Choose a value that accommodates maximum lifting needs with a safety margin.

3. Choose Boom Length

Boom length—the horizontal distance from the column centerline to the hook—determines coverage area. Longer booms increase reach but also raise costs and spatial requirements.

4. Consult Size Charts

Givens Engineering provides detailed charts correlating load capacity, HUB, and boom length to recommended column sizes. These serve as initial references, though final specifications may vary by application.
