Read on to discover tips from rigging and load securing experts at Columbus McKinnon – today, they’re sharing their top three safety tips to remember when you install your CM trolley.
Whether it’s a hoist, trolley or rigging equipment, proper use, inspection and maintenance is important to ensure operator safety at all times. Operators of material handling equipment should adhere to the manufacturer’s installation, inspection and maintenance requirements outlined in the product’s operation and maintenance manual (O&M manual).
Beam clamps and trolleys are critical components of a complete lifting system and demand the same attention to safety as hoists and below-the-hook rigging. The following three safety tips are important to consider when installing and inspecting a CM Series 633 Trolley.
1. CM Trolley Safety Tip: Consider the flange and shape of the I-beam to ensure proper fit and clearance. Measure the I-beam flange and check the distance between track wheel flanges. This distance should be 1/8 to 3/16 inch greater than the beam flange width for a straight runway. Additional clearance may be required for the trolley to negotiate track sections with curves. This clearance should be kept to a minimum to ensure the trolley operates properly on both the straight track sections and the curved track sections. See Figure 1.

2. CM Trolley Safety Tip: Ensure the equalizer pin nuts have been installed properly, in accordance with the O&M manual recommendations. The pins should be tight and locked position. Nuts should be regularly inspected to ensure they’re tight and secure during periodic inspections, which can be monthly or yearly – depending on service. Refer to your O&M manual, and/or ASME Standard B30.17.
3. CM Trolley Safety Tip: It is recommended that the trolley is mounted to the hoist prior to final installation onto the beam. Follow the washer and spacer instructions in your O&M manual to properly set the trolley based on the application’s beam flange width.
Please note: washer and spacer arrangement recommendations shown in the O&M manual are affected by structural variations. The accuracy of the final adjustment should be verified by the installer to ensure proper clearance is achieved between the trolley wheel flanges and the toe of the runway beam. See Figure 2.

Remember, any trolley installation should always be done in accordance with the manufacturer’s instructions or the recommendations of a qualified person. Improper installation can cause unequal loading on the trolley and side beam, and as a result can cause the trolley to fall from the beam. It’s also recommended that a load test is performed to 100-125% of the rated capacity of the crane after installation.
