Taking Care of Your CMC Lift

January 10, 2023
Safety & Maintenance Tips

Your CMC Tracked Aerial Lift has been built with the highest standard, quality, and parts. When owners perform regular and proper preventative maintenance, and all operators of the machine have been familiarized, trained, and certified, your CMC spider lift will work for decades, safely.

Preventative Maintenance Steps You Need to Follow:

‍1. Daily Safety Circle Check/Pre-Operation Check:

It is a requirement to perform a daily safety circle check of your lift and document it each time (per ANSI/SAIA A92.22.5.5). This is the same as documenting your everyday safety circle check for all your motor vehicles and trailers as required by the DOT.

If you perform this safety pre-operation check on a daily basis, this can be done in as little as one minute per side of your lift.

2. Manual of Responsibilities Document Book:

Read and follow the instructions of the OSHA required MANUAL OF RESPONSIBILITIES DOCUMENT ANSI/SAIA A92.22, a92.24 document included in your owner’s manual. 

We recommend this Manual of Responsibilities to be read on a consistent basis, beginning with page 3.

3. Required Training:

Always have your personnel properly familiarized and certified with your CMC tracked lift. This includes written attendance documentation according to the ANSI/SAIA A92.2 requirements & regulations.

Effective December 2019, OSHA published a new requirement that all aerial lift operators must be certified. 

This was implemented and became law as of June 2020.

If you do not already have this certification you are in VIOLATION.

You can sign up for classes with independent training facilities, or you can call our office for a formal documented certification training class.

4. Maintenance

Perform the required maintenance of your lift as instructed in your owner’s manual, on a daily, weekly and monthly basis. Many companies dedicate one full day per week to strictly perform maintenance on all of their equipment, including washing, waxing and documenting the maintenance performed. Records must be kept for 4 years.


1. Training

Do NOT allow anyone to operate ANY of your equipment who has not been properly familiarized and certified on how to operate it. This training must also be documented as per ANSI/SAIA standards & requirements.

2. Equipment Misuse:

Do NOT use your CMC manlift as a crane. This lift is designed to lift personnel only. Overloading and misuse of this lift as a crane will result in damage to the lift, which can result in severe injuries and even death.

3. Do Not Use This Lift As a Tie Off Point:

CMC tracked lifts are designed as a manlift. Manlift style MEWPS (mobile elevated work platforms) are not designed to sustain the severe shock loads that tie off points created when loads are dropped, likely exceeding the lift basket capacity by thousands of pounds beyond the basket load maximum limit of a manlift.

4. Log Loader/Brush Chipper Feeder Log Loader:

Do NOT use this man lift as a log loading or tree loading device to feed your chipper. Log loaders are devices designed to load logs and even though they are designed to pick up loads, they also still get damaged when overloaded. Man lifts are solely designed to handle personnel.

Do NOT use this lift as a log skidder to skid logs and trees.

Again, use a winch to winch logs and trees to a landing site, not your aerial lift.

Do NOT use this lift as a bulldozer or excavator to push over trees. Fixed uncut trees cause great stress and will damage your lift, creating dangerous operating conditions.

5. Entanglement:

It is required that you always inspect your work site prior to entering it. Pay close attention and constantly monitor your booms when maneuvering the lift between branches, structures and buildings.

If you do entangle the lift, STOP.  Review, understand the reason and action that entangled the lift to begin with. Slowly and carefully maneuver the booms away from the entanglement. ANSI/SAIA A92.

6. Snagging of Lift Booms:

If you do SNAG the lift, STOP.  Review, understand the reason and action that SNAGGED the lift. Slowly and carefully maneuver the booms away from the snag. ANSI/SAIA a92.

7. Dropping Trees on the Lift:

Some CMC Lifts are designed with a rear mounted turret. This allows you to work off the rear of the machine, creating a safe and clear drop zone away from the lift. Carefully plan your work so it can be accomplished safely, including NOT dropping trees and large branches on your man lift. Trees can weigh thousands of pounds. A dropping load doubles the weight for every foot dropped.

OSHA’s rule: "If it is not written down, it never happened”.
