Precautions during the use of self dumping garbage trucks

1、 Preparation before operation

Hydraulic system:

Check the hydraulic oil level (in a cold state, the level should be between the upper and lower limits of the scale), and the oil quality should be free of emulsification and impurities to avoid pump body wear caused by lack of oil.

Observe whether the pipeline interface of the self dumping garbage truck leaks oil (common leakage points: oil cylinder seals, high-pressure hose joints). If the leakage exceeds 5 drops per minute, it needs to be repaired immediately to prevent insufficient pressure from causing dumping failure.

Mechanical structure:

Check whether the connecting pin shaft and locking mechanism between the carriage and chassis of the refuse  dump truck are loose.

Test the lifting limit switch function to ensure that the car automatically shuts off when it reaches the maximum angle (usually 45 °~60 °), avoiding damage to the oil cylinder caused by "over top".

Braking and tires:

The pneumatic braking system needs to ensure a pressure of ≥ 0.8MPa and a brake pad thickness of ≥ 5mm (to be replaced if it is less than 3mm); The tire pressure must meet the load requirements (such as front wheel pressure of 8.5 bar and rear wheel pressure of 10 bar for a 10 ton vehicle).

Load coincidence compliance

Strictly load according to the rated load capacity indicated on the vehicle nameplate (for example, if a certain model of vehicle has a declared load capacity of 15 tons, the actual load must not exceed 16.5 tons to avoid overloading causing deformation of the frame or overload of the hydraulic system).

The distribution of goods is uniform, and it is prohibited to lean on one side (when the center of gravity deviates by more than 15% from the center of the carriage, it is easy to overturn during dumping).

2、 Loading and driving phase

Garbage type restrictions:

Prohibit loading goods that are too high or too long (such as waste steel bars exceeding the edge of the carriage by more than 30cm), to prevent scratching cables or obstacles during lifting; It is strictly prohibited to load flammable and explosive materials (such as lithium batteries, compressed gas tanks) to avoid friction and fire during dumping.

Construction waste and other bulk materials should be crushed to a particle size of ≤ 30cm to prevent blockage of the carriage floor or damage to the hydraulic cylinder.

Loading method:

When using a loader or manual loading, it is necessary to ensure that the goods fall evenly into the middle of the carriage to avoid concentrated impact on the bottom plate.

driving safety

Before starting:

Confirm that the locking mechanism of the refuse collection vehicle's compartment is fully closed (hear a "click" sound or observe the indicator light). Driving without locking may cause the compartment to open unexpectedly, leading to accidents.

During driving:

Speed limit requirements: unloaded speed ≤ 60km/h, fully loaded speed ≤ 50km/h, reduced to below 30km/h in mountainous or bumpy roads, avoiding sudden braking (braking distance increases by 40% compared to unloaded when fully loaded, requiring advance prediction).

It is prohibited to lift the carriage while driving on a sloping road surface (slope>15 °) to prevent the center of gravity from shifting and overturning.

The safe and efficient use of self dumping garbage trucks should follow the principle of "three inspections and three prohibitions":

Three checks: check compliance load, check hydraulic system, and check site safety before operation;

Three prohibitions: no overloading or uneven loading, no driving without locking, and no personnel approaching during lifting.

Through standardized operation and preventive maintenance, the lifespan of equipment can be significantly extended (hydraulic system lifespan under normal maintenance ≥ 8000 hours), while reducing accident rates (according to industry statistics, standardized operation can reduce the risk of tipping or hydraulic failure by more than 70%).
