- Periodically inspect cables, eyebolts, and shackles for damage.
- Do not operate with damaged, twisted, or frayed cable.
- Operating pressure must not exceed 100 PSI.
- Do not exceed rated capacity.
- Bal-Trol® eyebolts must be free to pivot and protected from impacts.
- Set horizontal and vertical speeds to the slowest acceptable speed.
- Do not attempt to operate a damaged or malfunctioning Bal-Trol®.
- Do not lift loads that are not centered directly under the Bal-Trol®.
- Do not attempt to lift loads that are anchored.
- Do not use a hook or fixture which does not securely hold the load.
- Do not maneuver loads over people, nor attempt to lift people.
- Do not leave a lifted load unattended.
- Do not remove a load unless tension has been released from the cable.
- Use of Safety Chain and Drop Stop® Load Arrestors are recommended.
Please contact Tri-Motion for applications assistance on your Bal-Trol air hoist requirements.
Most Common Hazards:
It would be impossible in the scope of this document to list all possible dangers and misapplications associated with the use of our products. However, in order to promote safe habits, the most common hazards are outlined and explained below:
Never exceed the rated lifting capacity. Keep out from under a raised load. Avoid shock loads and rapid speeds. Perform regular inspections. Perform regular maintenance. We recommend Safety Chains and Drop-Stop® Load Arrestors. Rating Lifting Capacity is shown on a sticker attached to the side of the Bal-Trol®. Never exceed the rated lifting capacity. The rated lifting capacity is the maximum load which should ever be applied to a Bal-Trol®, even when the product is new and when the load is uniformly applied - straight line pull only. Avoid side loading caused by lifting loads which are not centered directly under the Bal-Trol®. Mounting the Bal-Trol® to a 360 degree articulating arm allows for a larger work area without side loading or horizontal shock loading.
(See also Shock Loading below.) Operating pressure for any Bal-Trol® must not exceed 100 PSI.
Keep out from under a raised load. Take notice of the recommendation from the National Safety Council Accident Prevention Manual concerning all lifting operations:
"All employees working at cranes or hoists or assisting in hooking or arranging a load should be instructed to keep out from under the load. From a safety standpoint, one factor is paramount: Conduct all lifting operations in such a manner, that if there were an equipment failure, no personnel would be injured. This means keep out from under a raised load, and keep out of the line of force of any load."
Do not operate a load over people. Do not ride on loads. Do not allow the load to rotate. Tri-Motion offers swivel fittings to prevent rotation and prolong cable life. Do not leave a lifted load unattended. Do not manipulate loads by grabbing the cable or cable hardware. Tri-Motion offers a Slim-Grip handle for applications where the operator is inclined to pull on the cable for whatever reason, including lowering an empty hook. Do no remove a load unless all tension has been released from the cable. Do not use a hook or end effecter which does not securely hold the load. Do not attempt to lift loads that are anchored.
Shock Loads and Rapid Speeds When the Bal-Trol® is mounted on trolleys which slide along rails or tracks, avoiding impacting the Bal-Trol® into the ends of the tracks, especially at rapid speeds. Such horizontal shock loads can bend or break the eyebolts. Avoid shock loads. In applications where it is inevitable that the trolley will hit the ends of the track, mount the Bal-Trol® shackles to approved overhead-lifting chain, then connect the chain to the trolleys. This will help protect the eyebolts from the horizontal shock loads. Eyebolts should never be rigidly connected to the overhead support system, they should be free to pivot without binding up. Do not remove the provided shackles. All Bal-Trol® units are supplied with provisions to secure a safety chain. All overhead equipment should be secured for safety reasons. Vertical shock loads occur when the up and down speeds are too rapid. Adjust the up and down controls to the slowest acceptable speeds.
Regular Inspections Inspect cables regularly for visible damage and fraying. Do not cover any part of the dabble with tape, as this makes proper inspection difficult or impossible. Do not operate Bal-Trol® with damaged, twisted, or frayed cable. Inspect eyebolts regularly for visible damage, bending, cracks, wear, elongation, rust, etc. Do not operate Bal-Trol® with damaged eyebolts. The need for visual inspection cannot be overemphasized. No product can keep operating at its rated capacity indefinitely. Periodic inspections help determine when to replace parts such as cables and eyebolts, and thereby reduce possible hazards. Keep inspection records to help ensure periodic inspection intervals. Due to the diversity of applications, load weights, number of cycles, mounting arrangements, speed requirements, and environmental conditions, blanket recommendations for inspection procedures and frequency are not possible. When in doubt, inspect prior to each use. Carefully check for frayed strands, lumpy appearance forming underneath the coating of the cable, wear, deformation, cracks, elongation or bending of the eyebolts - sure signs of imminent failure. Immediately withdraw such items from use, and replace them. If down time is a concern, then keep spare parts or spare Bal-Trols® on site. Replacement cables and parts are available from Tri-Motion.
Regular Maintenance Do not attempt to operate a damaged or malfunctioning Bal-Trol®. If the Bal-Trol® leaks air, allows a load to gradually drift downward, malfunctions, or does not operate smoothly, this is an indication that it requires maintenance. If return authorization is obtained first, then such units can be sent back to Tri-Motion for thorough evaluation and repair. Tri-Motion offers cable replacement kits and seal kits which can be installed in the field by qualified personnel. The disassembly procedure provides an excellent opportunity to inspect the moving parts which are inside the Bal-Trol®. Sheaves should be checked to verify that they turn easily, and if not then new sheave bearings must be installed. Preventative maintenance can be performed on a scheduled basis, before the Bal-Trol® begins to malfunction or leak. Keep maintenance records to help ensure periodic maintenance intervals. Due to the diversity of applications and load weights, number of cycles, mounting arrangements, speed requirements, and environmental conditions, blanket recommendations for maintenance frequency are not possible. When in doubt, schedule preventative maintenance more frequently.
Safety Chains & Drop-Stop® Load Arrestors are recommended for safety of machines and product.
In case some safety considerations are still being overlooked despite the warnings listed above, the Drop-Stop® Load Arrestors can significantly reduce the chances of a hazard occurring. They operate on the principle of inertia, which is the same principle used in car safety belt systems. Drop-Stops® are used as a back-up device to the Bal-Trol®. The Drop-Stop® is designed to arrest the falling load which its falling speed exceeds the activation rate of the Drop-Stop®. It is recommended that all Drop-Stops® are returned for a yearly routine inspection and re-certification. Drop-Stops® are repaired exclusively by trained representatives.
