Prevent forklift rollover

Forklift rollover is a common condition, in which there are many examples of driver death caused by the rollover. The reason is not the forklift itself. Whether you are a domestic forklift or an imported forklift, it is more caused by the driver’s non-standard use of the forklift and his lack of understanding of the causes of forklift rollover. This paper will elaborate on various factors and safety precautions leading to forklift rollover.

1、 Causes of rollover of forklift truck under no-load driving

A forklift is an industrial vehicle working in narrow places with working devices in the front. The front wheel is designed as a driving wheel and equipped with a brake in the structure; The rear wheels are steering wheels. To improve the flexibility of its operation and maintain the stability of the vehicle body when passing through the concave-convex road.

However, this structure is not conducive to preventing the forklift from rollover.

A. There is no speed governor installed on the forklift structure.

B. Due to the high engine speed, the design speed of the forklift is 21.8km, but the measured value is as high as 28.37km/h, 30.7% higher than the design value.

C. According to the department leaders, the forklift drivers in their unit are very wild.

To sum up, the causes of the forklift rollover are analyzed as follows:

When an obstacle is suddenly found, the driver will subconsciously adjust the driving direction of the forklift, and the forklift is biased. At this time, the forklift is affected by centrifugal force, rollover forces. The driver subconsciously steps on the parking brake, and the inertia force generated by braking promotes the rollover of the forklift.

2、 Measures to prevent forklift rollover accidents?

1. According to the above analysis, the elements that should be controlled for no-load driving of forklift include:

A. During steering operation and turning, the forklift speed shall be strictly controlled.

B. When the forklift rollover occurs, stepping on the brake will only accelerate the forklift rollover.

C. If rollover has occurred, the driver must not jump. According to statistics, 4 drivers died and were seriously injured in 10 forklift rollover accidents; Among the five accidents in which the driver jumped out of the car during the rollover, there were 3 deaths and 1 serious injury, accounting for 80% in total. Among the five accidents of jumping escape, four were jumping in the same direction as the forklift rollover, with 100% casualties. Only one case was jumping in the opposite direction of the forklift rollover, and the drivers of the other five accidents were safe and sound because they did not jump. This shows that it is very dangerous to jump and escape in the process of forklift rollover, especially in the same direction as forklift rollover.

2. In terms of design and production, the measures to prevent forklift rollover accidents include:

A. When designing a forklift, the maximum speed shall be determined by comprehensively considering the use safety of the forklift.

B. Install speed governor.

C. A safety belt must be designed on the driver’s seat to force the driver not to jump.

3. Measures to be taken in other aspects:

A. In case of misoperation or accident, the forklift may roll over. At this time, the driver must not jump or step on the foot brake. Instead, he should hold the steering wheel tightly with both hands and turn his body in the opposite direction of rollover.

B. The forklift with the maximum lifting height not exceeding 1.8m is prohibited from installing the top guard frame. The roof guard is set to prevent small goods from falling over the shelf and hitting the driver when the forklift is lifted to a higher position. However, once the driver jumps or is thrown out during the rollover, it will cause injury to the driver.

4. Measures to be taken by the operator:

A. Do not jump when rollover occurs. According to the statistics of relevant scholars, 80% of the drivers who jumped out of the car were seriously injured or killed by top protection driving.

B. Drive in strict accordance with the operating procedures.

C. We should reasonably control the driving speed of forklifts, strive for efficiency on the premise of safety, and drive a civilized forklift.

D. In case of a rollover, don’t panic. Turn the steering wheel slowly to adjust the direction. Use oil collection to slow down. Never use the parking brake to stop forcibly.

Rollover is a frequent accident of forklift in loading and unloading. The objective reasons are the centrifugal force when forklift turns and the component force of gravity along the slope when forklift drives on the lateral slope; The main reason is that the driver did not do it in strict accordance with the requirements of rules and regulations.
