Description
Suspend industrial loads with Sumner PCB150C20WO 1-1/2 Ton chain-hoist capacity when maintenance crews need a 20-foot chain fall and overload protection. Experienced riggers gain controlled vertical positioning during utility, marine, and plant work, but can the upper support handle the complete hoist and load without low-headroom interference? Its zinc phosphate chain, fused brake, heat-treated load plates, hardened sheave rollers, and alloy steel hooks support manual lifting within the marked 1-1/2-ton rating.
Model 787454 identifies the PCB150C20WO configuration with a 1-1/2-ton capacity and 20-foot chain fall. Sumner product literature lists a 3,000-lb lifting capacity, low-headroom design, zinc phosphate chain, hardened steel load-sheave rollers, removable top hook, and 1.5x safety testing. Acme product data lists a 49.72-lb net configuration weight for the 20-foot model. Confirm current dimensions and nameplate data before installation.
Features of Sumner Chain Hoist
Utility maintenance, marine service, energy facilities, and industrial rigging require a compact premium chain block with overload protection and extended vertical reach. Trained operators can use this Sumner hoist after checking support structure, hooks, chain path, load balance, and rated capacity.
- 1-1/2-ton capacity supports compatible industrial maintenance and material loads.
- 3,000-lb lifting capacity is identified in Sumner product literature.
- 20-foot chain fall reaches elevated equipment and deep service locations.
- Built-in overload protection helps prevent lifting beyond rated capacity.
- Fused brake design supports controlled load holding and lowering.
- Heat-treated load plates support repeated chain-hoist service.
- Zinc phosphate chain helps resist corrosion during industrial exposure.
- Hardened steel load-sheave rollers support chain movement through the body.
Load Test Brake Control
Sumner literature identifies 1.5x testing for durability and safety, but no independent proof-load certificate, brake-holding measurement, chain elongation test, hook-throat measurement, or field telemetry was supplied. Do not treat 3,000 lbs as proof load or breaking strength. Shock loading, side loading, corrosion, poor anchoring, and incorrect hook engagement can compromise the chain, brake, hooks, and support structure.
Rigging Limits Service
The 20-foot chain fall, fused brake, heat-treated load plates, zinc phosphate chain, removable top hook, and alloy steel hooks support manual lifting in industrial environments. This hoist is not verified for personnel lifting, side-loaded hooks, shock loading, operation above 1-1/2 tons, or suspended loads over people.
- Inspect the chain for stretch, corrosion, kinks, cracks, gouges, and damaged links.
- Check alloy hooks, latches, brake parts, sheave rollers, and top-hook connections.
- Test overload protection and brake operation according to the Sumner manual.
Warranty Compliance Contents
Warranty information for model 787454 should be confirmed from current Sumner documentation. Package contents identify one 1-1/2-ton chain hoist with a 20-foot chain fall and overload protection. Verify current warranty terms, operator manual, inspection paperwork, chain specifications, hook details, and applicable ANSI/ASME and OSHA requirements before commercial service.
