Givens Engineering Introduces Precision Cantilever Crane Sizing
November 29, 2025
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.
Givens Engineering recommends the following steps to ensure optimal sizing for specific applications:
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.
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.
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.
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.
| Capacity | Model | Boom Length | HUB | Column Size |
|---|---|---|---|---|
| 100kg | J100 | 2m [6’7”] | 3m [9’10”] | 7×7 |
| 3.25m [10’8”] | 4m [13’2”] | 8×8 | ||
| 4.00m [13’1”] | 5m [16’5”] | 10×10 | ||
| Note: (H) = Heavy, (HH) = Extra Heavy, (XH) = Super Heavy. Other HUBs available upon request. | ||||
| Column Size | Base Plate | "DC" J100/250 | "DC" J1000 | "DC" J2000 |
|---|---|---|---|---|
| 7″ x 7″ | 30″ x 30″ x 5/8″ | 12.50” | N/A | N/A |
| 8″ x 8″ | 38″ x 38″ x 3/4″ | 13.2” | N/A | N/A |
| Boom Length | Model | "HF" | "HB" | Max "DE" (Typical) |
|---|---|---|---|---|
| 2m [6’7”] | J100 | 0.51m [1’8”] | 0.64m [2’1”] | 0.50m [1’8”] |
| J250 | 0.51m [1’8”] | 0.64m [2’1”] |
