5 Forbidden Operations For Legless Walk-behind Stacker

Many warehouse operators suffer rollover accidents on counterbalance stackers. If you are asking What Are The Safety Prohibitions For Walk-behind Counterbalance Stacker, strictly follow these five forbidden rules to avoid tipping risks.

A real accident case: An operator made a sharp turn right after lifting an off-center load. The front end tilted up and the whole stacker overturned, smashing racks and cargo. The truck was not overloaded, but offset load plus sharp steering destroyed balance. After enforcing these 5 rules, the workshop had zero rollover incidents for 18 consecutive months.

1. Load Restrictions (Key To Prevent Front-end Tipping)

No overloading. Always follow the rated load on the nameplate. Higher lifting height greatly increases tipping risk. Test data: A 1.5-ton stacker only safely carries less than 1 ton when lifted to 3 meters.

No off-center loading. Goods must sit squarely on both forks. One-sided weight breaks balance and easily causes side tipping.

No extended overhanging loads. Long outward cargo shifts the load center forward, and the rear counterweight cannot hold down the front mast.

2. Travel Operation Rules

No sharp turns or sudden brakes with raised loads. Slow down in narrow aisles, and keep speed below 3km/h under full load.

No cross travel or turning on ramps. Only drive straight uphill and downhill. Never park the truck on slopes for long periods.

Do not lift or lower forks while moving. Always come to a full stop before adjusting lifting height to avoid unstable shifting.

3. Operator Safety Rules

Never carry people on forks, and do not walk or work under lifted forks to avoid crushing injuries. Operators cannot work under fatigue or alcohol influence. Do not stick body parts into gaps between mast and frame. Only trained certified workers can operate the equipment, as counterbalance models have strict center-of-gravity characteristics.

4. Site & Environment Prohibitions

Do not operate on uneven or soft ground, which leads to uneven force and side rollover. Avoid overhead beams and pipelines when forks are raised to prevent mast collision damage. Do not leave the machine exposed to heavy rain for long hours. Water causes circuit failure and brake loss of control.

5. Parking & Maintenance Rules

Lower forks completely to the ground before parking, pull the handbrake firmly, and park on flat concrete ground. Stop using the stacker if counterweights are loose or missing; insufficient counterweight leads to complete loss of stability. Lock out and repair immediately if brakes fail or hydraulic pressure leaks. Never run the machine with known faults.

Following these 5 sets of rules will protect personnel and warehouse assets, cut downtime, and let you run the Legless Walk-behind Counterbalance Stacker steadily and smoothly.
