Most procurement teams get the lifting capacity number wrong — not because they can’t read a nameplate, but because they only look at the nameplate. Crane lifting capacity is not a single figure. It’s the result of at least four interacting variables: the weight of your heaviest load, the rigging and hook weight added on top of it, the duty class your operation demands, and the span your facility requires. Miss any one of those, and you’ll either under-specify a crane that fails early or over-specify one and spend money the project didn’t need. This guide is written for procurement managers and plant engineers sourcing industrial overhead cranes, gantry cranes, and EOT cranes. It walks through how rated lifting capacity is defined, what actually reduces it in real operating conditions, how to calculate the tonnage you need before you contact a supplier, and how Voitto Crane’s product ranges map to those requirements. If you already know your load weight and just need a quick product reference, jump to the capacity selection table in the section below. Quick Reference: Voitto Crane…

A freestanding jib crane — also called a floor-mounted jib crane or column-mounted slewing crane — delivers 360° rotational coverage from a single bolted column, with no overhead structure required. Capacity typically ranges from 0.5 to 10 tons, boom spans from 2 to 6 meters, and factory-direct pricing runs roughly $1,400 to $14,000+ depending on capacity and configuration. If you’re evaluating freestanding jib cranes for a workshop, warehouse, or production line, this guide covers the specs that actually drive selection decisions — duty class, boom length, foundation requirements, and what to ask your supplier before signing a purchase order. Quick Reference: Freestanding Jib Crane Specs at a Glance Specification Range / Value Lifting capacity 0.5 – 10 ton Boom (beam) length 2 – 6 m Lifting height 2 – 6 m Slewing angle 360° Work duty class A3 (ISO 4301 / FEM 1.001) Lifting speed 8 m/min (single) / 8–0.8 m/min (dual) Turning speed 0.46 – 0.76 r/min (varies by capacity) Power supply 380V, 50Hz, 3-phase (other voltages on request) Working temperature −20°C to +42°C Control Pendant push-button or wireless…

The sticker price on an overhead crane is the number everyone negotiates. The number that actually determines your total spend over 10 years is the annual servicing budget — and most buyers don’t model it until the first major breakdown arrives. For a 10-ton crane running at moderate duty in general manufacturing, the lifetime cost of operating and maintaining the equipment typically runs three to five times its purchase price. Most of that difference comes down to one decision: preventive servicing or reactive repair. This guide breaks down where overhead crane servicing costs actually come from, what a realistic annual budget looks like by duty class, and how to calculate the ROI of preventive maintenance in terms any finance team can follow. Where Overhead Crane Servicing Cost Actually Comes From Most maintenance budgets only capture the visible costs — the invoice from the service technician and the price of replacement parts. That covers roughly one third of what servicing truly costs. The full picture has three layers. Direct Servicing Costs: Labor, Parts, and Inspections Direct costs are what most buyers…
