IMPORTANT SAFETY INFORMATION
Please read, understand and follow all safety information contained in these instructions prior to the use of this hoist. Retain these instructions for further use. These instructions are applicable for Manually Operated Chain Hoists (Chain Falls) offered by Premium Tool & Abrasives Co. Ltd.
This hoist is designed to be used to lift a load from a stationary position. Only accessories specifically recommended by PTA Canada should be used with this tool. Use in any other manner or with other accessories could lead to unsafe operating conditions.
This unit must only be used in compliance with all applicable safety regulations and standards, including ASME B30.16, concerning installation, use, maintenance and inspection of equipment lifting devices.
IMPORTANT SAFETY INSTRUCTIONS
• Read, understand and follow the safety information contained in these instructions prior to using this tool. Keep these instructions for further reference.
• Always operate, inspect and maintain this hoist in accordance with American National Standards Institute Safety Code ASME B30.16 and any other applicable safety codes and regulations.
• Hoists are designed to provide a 4 to 1 safety factor. Supporting structures and load-attaching devices used in conjunction with this hoist must provide an adequate safety factor to handle the rated load, plus the weight of the hoist and attached equipment. This is the customer’s responsibility.
• Rigging: it is the responsibility of the operator to exercise caution and be familiar with proper rigging techniques. Refer to ASME B30.9 for rigging information.
• Do not exceed rated capacity. Hooks are designed to bend or stretch when overloading is detected.
• Do not use this hoist for lifting, supporting, or transporting people or lifting or supporting loads over people.
• During operation always ensure a firm footing. Operate the hoist from a location that will be clear of the load at all times. People must stay clear of load at all times.
• Before lifting a load, confirm that the chain hoist is in good condition and functioning properly. Inspect the chain hoist regularly. Never use a chain hoist when malfunction, unusual performance, damage, or extensive wear are found.
• Always keep the load chain well lubricated and protect it from weld spatter and other damaging contaminants. Never allow the load chain or hooks be used as a ground for welding and never touch them with live welding electrodes. Never use the hoist with twisted, kinked, damaged or worn load chains. Never attempt to lengthen the load chain.
• Never use a chain hoist as a sling. Always use proper slings and attachments in the correct manner and confirm that they are seated properly in the hook. Also confirm that the safety latch assembly has closed completely and not supporting any part of the load.
• Slacked load chain must be taken up carefully. While checking the balance of the load, lift and lower the load about 4” to test the brake system before lifting further. Loads must be lifted slowly.
• Never divert your attention when operating the chain hoist and never leave a suspended load unattended.
• Do not allow a load to drop, such as over the edge of a platform, while connected to a chain hoist. The sudden drop, even of a small distance, can cause a severe momentary overload, seriously damaging the chain hoist and possibly resulting in the loss of the load. This can occur at loads rated well below the rated capacity.
• Never adjust or repair a chain hoist unless you are qualified to perform hoist maintenance.
• Never modify the chain hoist. Approval from PTA is required for all nonstandard maintenance.
• Use only genuine PTA parts when repairing the chain hoist.
• Never remove or obscure the name plate on the chain hoist.
1. PREPARATION FOR USE
• Inspect carefully for any damage that may have occurred during shipping. Check for loose, missing, or damaged parts.
• Lubricate the load chain along the whole length with non-acid, non-corroding machine oil (See Figure 1).
• Examine the load chain to ensure that there are no twists (See Figure 2). 3 and 5 ton chain hoists have 2 falls of load chain, 10 ton has 4 falls. Twists can arise from the bottom hook being turned over through the load chains (See Figure
3). If a twist is found, reverse capsize the chain to correct.
• Confirm the brake is functioning properly by lifting a test load (10% of rated capacity) a few inches off the ground several times.
• Confirm that the supporting structure is strong enough to support the full rated capacity of the chain hoist with a generous factor of safety.
2. OPERATING INSTRUCTIONS
Hoisting (Raising the load)
• Pull the silver hand chain clockwise.
• Pull the silver hand chain counter-clockwise.
Overload protection comes with select models of PTA chain hoists and is calibrated at our facility prior to your purchase. The load limiter is integral with the hoist and prevents the operator from lifting loads outside the rated capacity of the hoist. When activated, the operator will notice the chain ‘slips’ during hoisting operations and the load will not leave the ground. If a load will not lift, the load is too heavy and you must find a larger capacity hoist. Despite the overload protection, it is still possible to lock the brakes on the hoist, rendering it inoperable, during several situations when the hoist is misused.
• Chain hoists are used for vertical lifting of loads from a stationary position. Most lifting malfunctions are due to violating this principle.
• If transferring a load to a chain hoist, the chain hoist must be used to lift the load from the previous stationary environment. The load cannot be dropped onto a chain hoist. This automatically locks the braking mechanism.
• Never allow the load to drop suddenly or to swing when transferring loads.
• Never use a chain hoist as a towing device. Chain hoists are for lifting vertically only.
• Always use from a stationary lifting point. Never lift the hoist and load with another lifting device, such as a crane.
3. OPERATING PRECAUTIONS
• Keep the load within the rated capacity marked on the chain hoist. An excess load may lead to an accident.
LOAD LIMITED: The chain hoist is overloaded when pulling the silver chain will not lift the load and instead slips during pulling. If the chain hoist is shock loaded, overloading is apparent if you cannot raise or lower the load and if the bottom hook is stretched so far that the clasp has sprung outwards.
NON-LOAD LIMITED: The chain hoist is overloaded when the hand chain is no longer operable by a single operator, or the clasp on the load hook will no longer close.
• Before operating, lift and lower the load about 4” (10cm) and test the braking system. Ineffective braking may lead to an accident.
• Loads must be lifted as slowly as possible. Load swinging and abrupt shocks will impose excessive stress on the chain hoist and could lead to overloading or brake locking.
• Extreme temperatures will affect the durability of the chain hoist. In subzero temperatures, loads must be lifted and lowered very slowly and carefully.
• When hooking, the load must be applied squarely to the centre of the hook and the hook must not come loose during operation.
• Mount the top hook for a fixed location. Ensure the fixed suspension point rests on the centre of the hooks saddle and that the hook’s safety latch is engaged.
• Do not side load the hoist. Chain hoists are for vertical lifting only.
4.CARE AFTER USE
• Always store your chain hoist in a no-load condition.
• Never leave or store the chain hoist with the brake system locked. Loosen the brake system by operating the chain hoist as if lowering a load.
• Always service and repair the chain hoist after use. Thoroughly clean the dust or if used in the rain, wipe off the dirt and moisture. Lubricate all moving parts of the hoist after use, especially the load chain, to prevent rust.
• Inspect the hooks and load chain for bends and any other type of defects. Also check to see if the hooks freely rotate. If any defect is found, replace the defective component before using the chain hoist again.
