Lifting Lug (Pinned) ASME BTH-1 Calculation
Engineering Spreadsheet — Instant Download
What This Spreadsheet Does
Designs pinned lifting lugs per ASME BTH-1, the US standard for below-the-hook lifting devices. Used for crane lifts of equipment, skids, vessels, and any rigged lift requiring code-compliant lug design.
What’s Inside the Excel File
- Inputs — lug plate thickness, hole diameter, pin diameter, edge distance, plate width, material grade, design lift load, Design Category and Service Class
- Design factor selection per ASME BTH-1 Category A/B and Service Class 0–4
- Tensile strength at pin hole net section
- Single-plane fracture capacity
- Double-plane shear capacity
- Pin bearing on lug plate
- Weld capacity at lug-to-base connection
Who This Is For
- Mechanical and structural engineers on lifting operations
- EPC project teams specifying crane lifts
- Equipment manufacturers and skid builders
- Rigging engineers and lift planners

Frequently Asked Questions
Design Category and Service Class — which to pick?
Category A for predictable loading, B for less predictable. Service Class 0–4 based on fatigue cycles per BTH-1 Table 2-1.
Pinned and shackle versions?
This sheet is pinned. For shackle-connected lugs, see our Lug from Shackle (Bechtel Method) sheet.
