hoists and accessories general information asme/osha safety standards columbus mckinnon cm hoists are manufactured in accordance with our interpretation of the american society of mechanical engineers code b30.16 for overhead hoists or b30.21 as applicable and u.s occupational safety and health act regulations at the time of manufacture users should check each installation for compliance with the application operation and maintenance requirements of these regulations and standards or frayed also take time to make sure the braking system works when you stop the controls the hook should remain steady if it creeps down take the hoist out of service again before you load the hoist test the limit switches if equipped with same carefully run the hook all the way up and all the way down taking care not to damage the hoist all hook-suspended hoists should have the top hook chain bottom hook and load all pulling in a straight line always consult your owner s manual for any questions about your hoist always remove a hoist from service if you spot any problem in the chain the hook the controls or the limiting devices there are test stands available from hoist manufacturers that help you thoroughly test a hoist to make sure it meets ansi-asme/osha standards always always make safety your number one priority for your sake and the safety of those who work with you always read the product manual for additional safety precautions do s and don ts order your cm hoist safety kit today it has everything you need to know to help keep your operation up and running in a safe effective manner ask your local stocking cm distributor we also guarantee that cm hoists and material handling products are built in accordance with listed specifications if any normally maintained part proves to have been originally defective we will replace the part at no charge f.o.b our factory within the duration stated in the cm literature which accompanied the product for specific description and limitations of any warranty refer also to the product accompanying literature we assume no responsibility for unauthorized repairs we reserve the right to change materials or design when in our opinion such changes will improve our product use of chain or replacement parts other than of cm manufacture may lead to dangerous operation accordingly cm cannot be responsible in such cases and the guarantee would be void care and use of cm hoists always pick the right hoist for the job paying close attention to the capacity and weight of the load osha standards recommend that you start with a complete regular inspection of your hoist always carefully inspect a hoist on a regular basis for wear damage and proper operation lever-operated and handoperated hoists should always be free to swivel on the upper hook the frame must not contact any objects make sure the chain or wire rope is clean and free of deposits and damage provided the chain appears in good condition lubricate it frequently according to the operator s manual never use extensions or cheater bars on lever-operated hoists they should move the weight on the capacity label with normal effort from one operator always make sure the hoist hangs free and is away from any objects or walls lever-operated and hand hoists are designed to lift loads by a single operator if you need two people you have the wrong hoist never use the load chain as a sling before you load an electric hoist make sure the controls move the chain/hook up when using the up button and down with the down button always inspect the control cords to make sure they aren t knotted looped cm industrial hoist lifetime warranty all columbus mckinnon cm hoists are thoroughly inspected and performance tested prior to shipment if any
