The three families of chain hoist
"Chain hoist" covers three distinct mechanical families, each suited to a different lifting task. Choosing the wrong family is a common cause of equipment misuse and premature wear, so it's worth understanding what each is actually for.
Manual chain blocks
Hand-operated hoists driven by an endless chain pulled hand-over-hand. Internal gear reduction multiplies the operator's effort to lift loads up to 20 t — though anything above about 3 t becomes very slow and operator-intensive. Compact, unpowered, no electrical infrastructure required. Good for low-frequency lifts, maintenance use, and applications where power is unavailable or the lift point is mobile.
Lever hoists (come-alongs / ratchet hoists)
Hand-operated through a ratcheting lever that the operator pumps. Designed to pull at any angle — horizontal, vertical, or inclined — which makes lever hoists the standard tool for tensioning, securing loads, pulling fabrications into position, and short-stroke vertical lifts in confined spaces where a chain block can't fit. Capacities span 750 kg to 9 t.
Electric chain hoists
Motor-driven hoists for repetitive industrial lifting. The standard hoist component for jib cranes, workstation cranes, monorails, and most overhead bridge cranes up to 20 t. Single-fall configurations prioritise speed; double-fall doubles capacity for the same motor at half the speed. Available in single-phase 240 V (limited to about 1 t) and three-phase 415 V for industrial workshop use.
Comparison table
| Manual chain block | Lever hoist | Electric chain hoist | |
|---|---|---|---|
| Power | Hand chain | Hand lever | Electric motor |
| Capacity range | 250 kg – 20 t | 750 kg – 9 t | 125 kg – 20 t |
| Lifting speed | Slow | Slow | Fast (1.5 – 8 m/min typical) |
| Operator fatigue | High at higher capacity | Medium | Low |
| Lift angle | Vertical only | Any angle | Vertical only |
| Best for | Maintenance, occasional lifts, mobile work | Tensioning, pulling, confined-space lifts | Repetitive production lifting, integrated cranes |
Capacity selection
Sizing a chain hoist needs three numbers: the working load (heaviest item you'll lift, plus rigging), the dynamic factor (multiplier for shock loading and accelerations — typically 1.1 for steady industrial use, higher for rough handling), and the duty class (how often it'll cycle, per AS 1418.1). Most workshops settle on a hoist rated 1.25× to 1.5× the heaviest expected load, with a duty class matched to the actual cycle count rather than the manufacturer's smallest available class.
Underspecifying capacity is the most common workshop mistake — a 1 t hoist used regularly to lift 950 kg loads will fail well short of its design life. Oversizing slightly is cheap insurance.
Standards and documentation
Industrial chain hoists supplied for Australian workplace use must comply with:
- AS 1418.2 — powered hoists (electric chain hoists)
- AS 1418.18 — applicable to crane and hoist runways
- ISO 3077 — load chain grades and traceability
- AS 2550.1 — in-service safe use and inspection
- AS 3760 — electrical safety testing of in-service equipment
Every hoist Sorian supplies ships with the manufacturer's test certificate, an AS 1418 compliance statement, the load chain ISO 3077 grade certificate, and the documentation pack needed for your facility's plant register. We don't supply retail-grade hoists — for industrial workplace use, the certification chain matters.
Applications across Australian industry
- Manufacturing and fabrication — die change, weld positioning, plate handling
- Mining maintenance — workshop hoists for component change-outs
- Defence and aerospace — assembly and overhaul facilities
- Marine and shipbuilding — engine room maintenance, slipway work
- Food and beverage processing — equipment maintenance, sanitary applications
- Construction — temporary lifting for installation work, lever hoists for steel positioning
- Utilities and infrastructure — substation valve handling, transformer maintenance
- Resource sector — fixed plant maintenance and shutdown work
The Sorian process
- Application brief — capacity, lift height, duty cycle, environment, integration with existing equipment
- Engineering review — selection across the three families, sizing for AS 1418 duty class, electrical compatibility
- Quote — typically same-day for standard configurations, with the engineering rationale included
- Supply — usually 2-4 weeks lead time; common configurations stocked or available shortlist
- Optional installation — where the hoist is integrated with a crane, jib or runway, we install and commission
- Documentation — manufacturer's test cert, AS 1418 compliance statement, load chain ISO 3077 cert, O&M manual
Frequently asked questions
Chain block vs lever hoist vs electric chain hoist?
Chain block: hand-chain operated, vertical lifts, slow but unpowered. Lever hoist: ratcheting lever, any angle, ideal for tensioning and confined spaces. Electric chain hoist: motor-driven, fast, the standard choice for repetitive industrial lifting.
What capacities are available?
Manual blocks 250 kg to 20 t. Lever hoists 750 kg to 9 t. Electric chain hoists 125 kg to 20 t. Above 20 t, switch to wire rope hoists.
What standards apply?
AS 1418.2 (powered hoists), AS 1418.18 (runways), ISO 3077 (load chain), AS 2550.1 (in-service inspection), AS 3760 (electrical safety).
Single-fall or double-fall?
Single-fall is faster, double-fall doubles capacity at half speed. Above 5 t, double-fall is the default.
Do chain hoists need design registration?
Standalone hand and lever hoists generally don't. Powered hoists installed in a crane system may trigger registration on the assembled crane — handled by us as part of supply.
Hardware-store vs industrial-grade?
Hardware-store chain blocks lack the documentation needed for Australian workplace use. For industrial plant registers, source from a supplier that provides full certification chain.
