Tips And Suggestions For Using Used Excavators In Different Terrains

In industries such as infrastructure construction, mining and agricultural construction, second-hand excavators have become an important choice of mechanical equipment for many companies due to their high cost-effectiveness. However, different terrains put forward higher requirements on the adaptability and operating skills of excavators. This article will start from four perspectives and analyze in detail the practical suggestions and precautions for using second-hand excavators under different terrain conditions to help users operate scientifically, extend the life of equipment, and improve construction efficiency.

Operation suggestions for mountainous and hilly terrain

Choose a suitable second-hand excavator model

Mountainous and hilly terrains are mostly slopes and hard rock formations. It is recommended to choose a second-hand excavator with the following configuration:

Crawler chassis: provides stronger grip and is suitable for uneven terrain;

Small or medium-sized models (such as SANY SY75, KOMATSU PC78): convenient for transfer and efficient excavation;

Models with breaker function: convenient for rock crushing operations.

Safety regulations for slope construction

Avoid horizontal climbing and choose vertical uphill and downhill;

The center of gravity of the machine must be stable to avoid rollover;

The operator must use a seat belt and pay attention to obstacles ahead.

Key maintenance suggestions

Mountainous working conditions are dusty and vibrate strongly. It is recommended to:

Clean the air filter every 50 hours;

Regularly check the chassis tracks and tensioning devices;

Strengthen the maintenance of the hydraulic system and cooling system.

Strategies for dealing with soft soil foundations and muddy areas

Assessment of foundation bearing capacity

Before entering soft soil foundations (such as swamps, river beaches, and farmlands), the following assessments should be conducted:

Use geological radar or geological testing to determine bearing capacity;

If the bearing capacity is less than 50kPa, floating pads or rails should be used for laying.

Tips for dealing with stuck vehicles

When a second-hand excavator gets stuck:

First stabilize the equipment posture and do not force it to lift;

Use the bucket to push back or climb out with force;

If necessary, use wooden boards/track shoes to increase the support force.

Maintenance measures to prevent water corrosion

After operation, the tracks and mud on the bottom of the vehicle must be washed;

Check and replace contaminated hydraulic oil;

Insulate the electrical parts in advance.

Tips for use in deserts, Gobi and arid areas

The impact of high temperature + dry environment on equipment

High temperature causes the viscosity of hydraulic oil to decrease and the efficiency of the cooling system to decrease;

Sand and dust intrusion may damage the engine and hydraulic system.

Application suggestions

Configure sand and dust protection kit (such as air pre-filter);

Use high temperature resistant hydraulic oil and coolant;

Appropriately increase the downtime interval during operation to prevent the system from overheating.

Precautions for walking on sand

Keep driving straight at low speed and avoid frequent turns;

If stuck in a sand pit, use bucket + reverse track to get out of trouble;

Avoid working in strong winds to prevent particles from damaging the equipment.

Special operation strategies for urban construction sites, narrow spaces and hard surfaces

Selection strategy for narrow sites

Urban construction sites are mostly concrete floors and limited spaces, so priority should be given to:

Small excavators (such as YANMAR VIO55, BOBCAT E35);

Equipped with rubber tracks + adjustable boom;

With zero tail slewing function, it is convenient for working against the wall.

Avoid damaging the road surface or underground structures

Get a topographic map before operation to avoid underground cables/pipelines;

Add cushioning materials before the bucket lands to avoid scratching the ground;

Do not dig in the same location for a long time to prevent foundation settlement.

Urban noise and emission control

To meet environmental protection requirements:

Choose a low-noise engine + environmentally friendly hydraulic oil;

Replace old mufflers in time;

If modification is necessary, use environmentally friendly accessories certified by the manufacturer.

Summary and purchase recommendations

When using second-hand excavators under different terrain conditions, it is necessary to select equipment and adjust the operation methods according to local conditions. The following is a brief comparison suggestion:
