Frequently Asked Questions
What is the difference between a manual chain hoist and a lever hoist?
Manual chain hoists are designed primarily for vertical lifting. Lever hoists are designed for lifting, pulling, positioning, and tensioning applications using a ratcheting lever mechanism.
Can manual hoists be used for continuous production lifting?
Do not use manual hoists for continuous high-cycle production operations. Repetitive lifting increases operator fatigue and reduces operational efficiency.
Can a manual hoist be installed on a trolley system?
Manual hoists can be installed on compatible beam trolley systems. Beam size, flange width, and rated load capacity must match hoist and trolley specifications.
When should electric chain hoists be used instead of manual hoists?
Use electric chain hoists when lifting frequency, operational speed, or vertical travel requirements exceed practical manual operation.
Can manual hoists be used outdoors?
Manual hoists used outdoors require environmental protection appropriate for moisture, corrosion, and exposure conditions. Unprotected hoists exposed to corrosive environments will experience accelerated wear.
Are manual hoists compatible with gantry crane systems?
Manual hoists are commonly installed on portable and manual gantry crane systems. Beam compatibility and structural load ratings must be verified before installation.
Can lever hoists be used for side pulling applications?
Do not use lever hoists for unsupported side pulling unless the equipment is specifically designed and approved for that loading condition. Side loading can damage load-bearing components and create unsafe operating conditions.
Are manual hoists suitable for personnel lifting?
Standard manual hoists are not designed for personnel lifting applications. Personnel lifting requires equipment specifically rated and approved for human suspension.
