CAT CLASS: HQ-10356

2-5 ton Chain Hoist

The 2-5 ton chain hoist class handles heavy shop and structural lifting at 3 to 5 ton capacity under a beam. This mid-to-heavy-duty rung sits above 1-2 ton models and below 5+ ton hoists, serving industrial fabrication, heavy equipment maintenance, and structural steel erection. These hoists are typically available in both manual and powered configurations from manufacturers including Harrington, Demag, Yale, and Columbus McKinnon.

Spécifications clés

Spécification	Plage typique	Signification
Lifting capacity	4,409–9,259 lb (2–4.2 t)	Maximum rated load the hoist can safely lift vertically
Load capacity	4,409–9,149 lb (2,000–4,150 kg)	Metric expression of safe working load for international specifications
Chain configuration	Multi-fall for higher tonnage	Higher-capacity models in this class often use multiple chain falls to distribute load
Lift height	Varies by chain length	Vertical travel distance depends on chain length specification and reeving configuration

Comment choisir

The 2-5 ton chain hoist is appropriate for heavy shop machinery installation, structural steel assembly, and equipment maintenance tasks where loads consistently fall in the 3 to 5 ton range. For lighter fabrication work, engine removal, or loads under 2 tons, the 1-2 ton Chain Hoist offers easier handling and lower rigging requirements. When loads regularly exceed 4 tons or structural work demands greater capacity margins, the 5+ ton Chain Hoist provides the necessary rating and typically more robust trolley and beam integration.

Ce que cette taille peut gérer

Lifting heavy machine tool components during factory equipment installation
Positioning structural steel beams in industrial building erection
Removing and installing large industrial gearboxes and drive assemblies
Handling heavy molds and dies in manufacturing facilities
Lifting HVAC units and heavy mechanical equipment in plant maintenance
Rigging heavy fabricated assemblies in steel fabrication shops

Sécurité et opération

Hoists must be suspended from beams or supports rated for at least the hoist's working load limit plus hoist weight
Load chains require regular inspection for wear, stretching, and deformation; retirement criteria follow ASME B30.16
Operators must ensure loads are balanced and rigging is properly secured before lifting; side-loading damages chains and hooks
Overload protection devices and upper limit stops prevent exceeding rated capacity and chain over-travel on many powered models

Transport et logistique

Manual units transport in service vans or pickup beds; powered models may require crated shipping
Electric chain hoists in this class typically weigh 100-200 lbs and can be hand-carried by two workers or moved with hand trucks
Beam trolleys and suspension hardware often ship separately and require coordination with rigging equipment

Alimentation

Manual chain hoists in this class require no power; operator applies force through hand chain
Electric models typically specify 115V single-phase for lighter capacities or 230V/460V three-phase for higher tonnage
Pneumatic variants operate on compressed air at 90-120 PSI from shop air systems

Questions fréquentes

What beam flange width is required for this hoist class?

Beam trolleys for 2-5 ton hoists typically accommodate I-beam flanges from 3 to 8 inches wide, though specific trolley models have defined flange ranges. The beam itself must be structurally rated for the applied load and hoist weight.

Can a 2-ton hoist safely lift a 2-ton load?

A hoist rated at 2 tons can lift 2 tons at its working load limit, but rigging angles, sling ratings, and dynamic loading must be factored into the total system. Many applications apply a safety factor and select capacity above the bare load weight.

What differentiates manual from electric models in this capacity range?

Manual chain hoists require operator effort through a hand chain and are slower but need no power source. Electric models lift with the press of a pendant button, offer faster lift speeds, and are preferred for repetitive or sustained lifting tasks.
