Jib Crane Selection Guide | Load, Span & Safety Standards

When overhead cranes are overkill and manual handling slows down production, a jib crane is usually the right fix. It covers a 3–6 meter radius, takes up less than 1㎡ of floor space, and cuts wait times at individual workstations. This guide skips the sales pitch and focuses on what actually matters when buying, installing, and running one.

We will guide you through the key factors and a step-by-step process to help you make an informed decision.

1. Understand Your Lifting Requirements

2. 5 Parameters That Actually Determine Performance

3. Keep It Running: A Realistic Maintenance Rhythm

1. Which Mounting Style Fits Your Layout?

Rule of thumb: Mount to a wall or column first. Use floor-mounted only when structural support isn’t available. If equipment or racks block a straight arm, go articulating. Don’t oversize the span just for clearance—excessive deflection hurts hoist tracking and increases motor strain.

2. 5 Parameters That Actually Determine Performance

Duty Class (FEM/ISO): A3 for occasional maintenance. A5 for standard shift work. A6/A7 for continuous, high-cycle production. Never run an A3-rated crane on a three-shift line.

Effective Span vs. Total Length: Manufacturers quote total arm length. Subtract the hoist trolley width, end stops, and a 150–200mm safety margin to get your real working radius.

Slewing Bearing Type: Cross-roller bearings offer precision and long life with minimal maintenance. Sleeve/bushing designs are cheaper but wear faster under frequent cycling and need regular greasing.

Limit Switches & Buffers: Mechanical stops plus electrical cut-offs are non-negotiable. Add rubber bumpers and warning alarms if the crane swings near racks or conveyors.

Corrosion & IP Rating: Standard industrial paint works for dry shops. For washdown, chemical, or coastal environments, specify IP54+ motors and hot-dip galvanized or epoxy-coated structures.

Procurement tip: Ask for FEA reports or load-deflection curves. Require 110% static and 125% dynamic load tests before handover, and keep the third-party certificates on file.

3. Choose the Basic Crane Configuration

Jib cranes are simple, but “simple” doesn’t mean “ignore it.”

Daily: Check wire rope for kinks/broken strands, inspect the hook throat opening, listen for slewing noise, test limit switches.

Monthly: Lubricate the bearing and sheaves. Tighten anchor/wall bolts. Verify brake slip (should be ≤1/100 of lift height).

Annually: Third-party inspection, full load test, replace worn pins, recalibrate load limiters, check grounding.

Hard safety rules: Never side-pull. Never exceed rated capacity. Never walk under a suspended load. Most incidents come from rushing, not equipment failure. Post a clear “10 Don’ts” sign at the station and require hands-on sign-off before new operators use it alone.
