Excavator operator need know dangerous conditions in jobsites

Excavator operators usually work out in the field or construction sites; therefore, cautious investigation on the worksites is crucial to the safety of the excavator operator and to the safe operation. First of all, the operator should check the terrain and ground condition and use the safest operating method, try to avoid traveling or operating the excavator in areas with risk of landslide or falling stones, near cliffs, road shoulders or trenches, because the soft and loosen ground in these areas may not bear the excavator’s weight and vibration, as a result, the machine might sink or tumble down. The ground may become softer after heavy rain, explosion or earthquake. If the excavator has to work on a dam or near a ditch, vibration and machine weight may trigger a landslide, thus protective measures have to be taken prior to operation in order to prevent the excavator from tumbling down or falling over. For instance, to solidify the ground, keep a safe distance away from the ditch and assign a signal man when necessary.

If there are underground water mains, gas lines, cables or high voltage electric wires on the worksite, the large excavator operator must inform and ask related utilities providers to mark the area, and be careful not to cut any lines while digging the ground. When necessary, in order to prevent any unauthorized personnel from entering the construction site, it’s necessary to assign a signal man for the excavator operator and build a fence when operating on a highway. In addition, the operator must be extremely alert when operating on frozen ground as the excavator operation will cause the ambient temperature increase, which may result in soft and slippery ground. When traveling or operating the excavator in shallow water or soft ground, the operator has to check the type and condition of rock bed as well as the depth and water flow in advance.

The uses of excavators in flood relief operation

In summer, heavy rains and storms usually cause significant water level rising. Excavators can play a big role in the emergency relief and rescue. This year, the flood in China has affected more than 1000 counties and causes serious damage to local farmlands, roads, houses, dykes and dams across southern China. The emergency rescue teams used large excavators to clear the blocked roads triggered by landslides in Hunan province. Most of the large excavators are equipped with multi-use working devices besides standard bucket, such as a breaking hammer, a ripper and a log gripper. If the river banks or dams are broken because of the tornado, barrier lakes are easily to put people’s life at risk, in this condition, large excavators are used to repair the river banks, dredge the sluggish river and clean the floaters in rivers, lakes.

In particular, the high-reach excavators displayed great performance and became to be the main force in the flood relief. The high reach excavators are built with optional longer boom and arm besides standard working mechanism. They are widely used for yards, subway, canals, and housing demolition. During the flood relief, high reach large excavators played a key role in cleaning the sluggish rivers and consolidating river banks with its advantage of longer boom and arm. The excavators used in Anhui province undertaking the task of building a new temporary embankment under a bridge are from Sany Heavy Industry. Its key structural components are made of reinforced steel, highly wear-resistant. The advanced hydraulic system and undercarriage of excavators ensured a safe and stable operation even while traveling in the water. 

Usage Information of Mini Excavator

Many excavator operators want to learn about the usage of an excavator. The daily routine work of an operator who uses Sany SY75 excavator is as follows:

The operator's excavator is used in municipal construction, the reconstruction of the city moat. This city moat needs rebuilding for environmental beauty and increase in usable area. Basically speaking, it is a simple work for ditching and repairing the slope, even a green hand can do the job. But during the working process, patience and carefulness are still very important. At the initial stage of the project, the bucket is used to dig a ditch in the middle of the watercourse. The width of the ditch is nearly the same size of the bucket. During the excavation, one may use a bracing wire to make sure the ditch is done in a straight line. After ditching, the operator needs to trim the slope of the watercourse. Due to the narrow scope of the watercourse, more attention should be paid. However, the operator's excavator is in the category of mini excavator, making it easy to get job done. The excavator can also be used for dismantling the house, especially the flat house. But the bad side of this work is that the excavator will become very dirty with a thick layer of soil.

The operator also gives some advice on how to choose an excavator. The excavator should be matched with the working condition and working intensity. Just like SY75, it is suitable for the jobs in rural area.

Sany Excavator Works in Qatar

Eleven units of Sany’s machines have participated in the project of impounding reservoir construction, including nine units of excavators, two units of graders and two units of trailer pumps. In such an extremely dry country, this project is a national strategy of Qatar for water reservation.

Sany’s excavators win favor from all operators from different countries, since they not only look elegant but also perform well. These excavators on the working site have different responsibilities, such as excavating, loading or smashing. The operators speak highly of Sany’s excavators, since they are powerful, efficient and durable. Even though the local temperature of Qatar is always around 30-50 degree centigrade, these excavators resist the high temperature and perform steadily. Besides the excavator itself, the meticulous after-sales personnel also add the attraction of the excavators.

One Indian operator is excited about the excavator equipped with quartering hammer. He says Sany’s products are common in India, but the hydraulic excavator equipped with quartering hammer is fancy for him. Adopting the hydraulic pressure with nitrogen, the quartering hammer’s strength is quite strong. Even if the working condition in Qatar is stony, hot and dry, the quartering hammer is all-conquering. Unlike other quartering hammers which are easily broken, the life span of Sany’s machine is quite long. The high quality material, precise processing technique and thermal treatment for the surface of cylinder and piston not only lengthen the life span of the quartering hammer, but also the life span of the whole excavator.
