Keep away from shovel machine

Keep away from shovel machine

What kind of accident is about to happen?

The battery of a neglected hydraulic shovel has died, and a small dump truck driver is using battery cables to connect it to the battery of his truck.
The drag shovel operator is trying to start the engine.

Can you predict what's about to happen?

Look what happened!

The drag shovel operator started the engine and accidentally hit the rotate lever, rather than the lever to raise the boom. The shovel turned suddenly, crushing the driver of the small dump truck between his truck and the counterweight of the shovel.

Tips for preventing similar accidents

1. When starting an engine, confirm that safe conditions exist within the operating range.
2. Confirm differences in control patterns for different models of machinery.
3. Do not enter the operating range of a hydraulic shovel.

Take notice when drive on the road with rock fallen

Take notice when drive on the road with rock fallen

What kind of accident is about to happen?

A bulldozer heading to collect lumber is traveling along a work road created by excavating the side of a mountain road, and piling it up along the ravine side of the road.
Some rocks have fallen from the mountainside and are blocking part of the roadway, so the bulldozer operator is trying to avoid them.

Can you predict what's about to happen?

Look what happened!

When trying to go around the pile of rocks, the bulldozer ended up hitting the shoulder on the ravine side of the road. The shoulder, which was made of dirt, collapsed, and the bulldozer tumbled down the side.

Tips for preventing similar accidents 

1. Machinery operators should recognize that shoulders are unstable. If a shoulder is at risk of collapsing, halt work and take necessary safety measures.
2. Inspect work roads before starting work. To ensure safe travel, remove obstacles in the road and reinforce weak shoulders.
3. When there is a risk of a bulldozer tumbling down a shoulder or incline, take safety measures, such as assigning someone to serve as a guide, or installing guardrails or signs.

Dangerous sittuation on the slope of mountain

Dangerous sittuation on the slope of mountain

Any accident foreseen in this frame?

This is a worksite for building a construction road. A hydraulic excavator is pulling hewn logs with a chain to remove them from the site.

Now what accident do you anticipate from this picture? 

This is the accident resulted!

The tugged logs were sent leaping and went down the slope on the valley side. Linked with a chain, the upper structure of the machine was then widely swung, then lost balance and rolled over. The operator was crushed under the fallen machine.

Tips for forestalling similar accidents

1. Use a special purpose machine for transport of logs such as skid loaders.
2. Operate a construction machine within its maximum capacity.
3. Fasten a wire rope securely to the logs.

Safety when using excavator crane concrete water pipe

Safety when using excavator crane concrete water pipe

Any accident foreseen in this frame?

At a construction site of burying city water pipes, a hydraulic excavator is traveling with a pipe weighing 53 kg that is hung with a wire rope fixed at the center. A worker is holding the pipe with his hand to prevent it from swaying.

Now what accident do you foresee occurring in this frame?

Excavator not enough capacity for weight heavily steel plate

Excavator not enough capacity for weight heavily steel plate

Any accident foreseen in this frame?

In the construction of provisionally closing a dam, a hydraulic excavator is lifting up those steel plates that were spread over the embankment in order to load them on a truck waiting at the back. The size of one such plate is 6,000 mm in length x 1,500 mm in width x 20 mm in thickness.

Now what accident do you anticipate occurring in this frame?

This is the accident resulted!

The hydraulic excavator lifted up a steel plate and began to swing to the right, when the left undercarriage was floated and fell into the lake together with the operator. He was drowned.

Tips for forestalling similar accidents

1. Use a special mobile crane with an ample capacity.
2. Observe the provisions set forth in the Article 164 of Ordinance on Industrial Safety and Health, when using a hydraulic excavator in lieu of cranes for lifting cargos.

Take notice above your head when lift heavy concrete pip

Take notice above your head when lift heavy concrete pipe

Any accident foreseen in this frame?

A hydraulic excavator lifts up a concrete pipe weighing approx. 1.2 tons with a hook attached to the bucket and is about to lower it to a 4.7 meter-deep gutter for burial.

Now what accident do you anticipate from this picture?

This is the accident resulted!

While it was lowered, the concrete pipe hit a brace for the gutter. The wire rope slackened momentarily and let itself slip off the hook. It went straight down, directly hitting a worker below. He was killed.

Tips for forestalling similar accidents

1. Do not make an unauthorized use of the hook attached to hydraulic excavators.
2. Carry out a check of the hook prior to the start of the day's work.
3. Always take good care of a latch system for the hook.
4. Limit the max. lifting weight to less than 1 ton. And do not exceed the machine's max. lifting capacity, either.
5. Do not go under hung object, while in operation.

Stop the engine and pull out the ignition key, Have to remember

Any accident foreseen in this frame?

An operator leaves his hydraulic excavator with the engine running. He wants to fetch a slinging clamp that was left unattended and puts it at the foot of the operator's seat for transportation.

Now what accident do you anticipate from this picture?

This is the accident resulted!

When the operator put down the clamp on the floor, he placed it on the left travel control pedal by mistake. That started the machine to move backward and turn to the left. He was run over by the undercarriage and killed.

Tips for forestalling similar accidents

1. When leaving a construction machine, lower the bucket to the ground, stop the engine and pull out the ignition key.
2. Do not bring in any unnecessary items.

Another sittuation of crane not enough capacity

Another sittuation of crane not enough capacity

Any accident foreseen in this frame?

A hydraulic excavator was employed in an underground construction work. Workers are trying to pull it up with another hydraulic excavator. The former weighs 2.7 tons and the latter 11.5 tons.

Now what accident do you anticipate from this picture?

This is the accident resulted!

The larger hydraulic excavator lifted up the small one and tried to swing, when the former lost balance all of sudden and fell off the ground. The lifting operator jumped out of the machine to escape the danger in vain. He was killed, sandwiched between the fallen machine and the wall.

Tips for forestalling similar accidents

1. If an object weighing over 1 ton is to be lifted up, be sure to use a crane, not a hydraulic excavator.
2. When lifting up an object under 1 ton using a hydraulic excavator, observe the instructions set forth in the Article 164 of Ordinance on Industrial Safety and Health Law.
