We have previously talked about the differences between diesel scissors and electric scissors (one of which is the power difference) and how to choose the right scissors. In fact, in addition to their power methods, they are also different. Take diesel scissors as an example. If we go a little deeper, diesel scissors can be divided into large diesel and small diesel. Let's start to introduce the differences between large diesel and small diesel.
Power performance: The big diesel is powerful, the small diesel is light and flexible

First of all, large diesel engines usually have larger displacement and higher power, which enables them to output powerful power and have better torque performance. For some large diesel scissor-type aerial work platforms, after being equipped with large diesel engines, they can easily carry heavier operators and a large number of tools and materials, and when performing aerial work, they can still operate stably and complete tasks efficiently regardless of complex working conditions such as strong winds or rough ground. Large diesel engines also have significant advantages in climbing ability, which can ensure that the equipment can work normally in different terrain environments.

The second is small diesel engines. Small diesel engines have relatively small engine displacement and power. Although they are not as powerful as large diesel engines in power output, they have unique advantages in some light operation scenarios that do not require high power. In the indoor decoration scene, small diesel engines drive diesel scissor equipment to flexibly shuttle through narrow spaces. Whether it is carrying lightweight decoration materials or performing local high-altitude decoration operations, its lightweight characteristics make the operation more convenient and will not cause energy waste due to excess power.

Fuel consumption: Large diesel has a large amount of fuel and high fuel consumption, while small diesel has a small amount of fuel and significant energy saving

Due to the large engine power of the large diesel, more fuel is consumed during operation to maintain a strong power output. Especially when the equipment is in a high-load operation state for a long time, the fuel consumption of the large diesel will be more obvious. Although the fuel consumption of the large diesel engine is high, its powerful power ensures the rapid loading and unloading of cargo, and also reduces the time of ship stoppage. From a long-term perspective, it can still reduce the overall operating cost.

The design of the small diesel engine focuses more on meeting the needs of light-load operations, so the fuel consumption is relatively low. When the diesel scissor equipment is used for some intermittent and low-intensity work tasks, the small diesel engine can maintain the operation of the equipment with lower fuel consumption. For some small enterprises or individual users who do not use it frequently and have strict cost control, the energy-saving characteristics of the small diesel are undoubtedly an important advantage.

Equipment adaptation: Dachai is suitable for large equipment, Xiaochai is suitable for small equipment

The powerful power of large engines determines that it is more suitable for large and heavy diesel scissor equipment. These large equipment usually have larger working platform size, higher lifting height and stronger carrying capacity, which can meet the needs of diversified high-altitude operations in large projects. When large scissor trucks are transporting heavy goods, they also need large diesel engines to provide strong power to ensure that the goods are safely and quickly transported to the right place.

Due to its small size and moderate power, small diesel engines are very suitable for small and compact diesel scissor equipment. This type of equipment usually has a small size and flexible control performance, which is convenient for operation in narrow spaces. Whether in the field of interior decoration, small diesel scissor equipment can easily enter narrow areas such as rooms and corridors to work.

Maintenance: Large diesel engines have high maintenance requirements, while small diesel engines are easy to maintain.

The structure of the Dachai engine is complex and has many parts, which makes its maintenance work relatively cumbersome. In daily maintenance, more parts are needed for a series of operations such as inspection, cleaning, and replacement. Due to the high power and high working intensity of the Dachai engine, the quality requirements for consumables such as engine oil and coolant are also higher, and the replacement cycle is relatively short. The difficulty and cost of maintenance will also increase accordingly, which requires professional maintenance personnel and equipment inspection and maintenance. This means that more time and money costs need to be invested in maintenance.

In contrast, the engine structure of Xiaochai is relatively simple, the number of parts is small, and its maintenance work is relatively simple. The power of the Dachai engine is small and the working intensity is not that high. The quality requirements for consumables such as engine oil and coolant are relatively low, and the replacement cycle is relatively long. The maintenance difficulty and cost are relatively low. When a fault occurs, due to the simple structure, the difficulty of maintenance is relatively low, and general maintenance personnel can perform maintenance with simple training.

In summary, there are many differences between large and small diesel scissor lifts in terms of power performance, fuel consumption, equipment adaptation, and maintenance. Therefore, when choosing diesel scissor lift equipment, users should choose the equipment that suits them based on actual operating needs, applicable scenarios, and other factors to achieve efficient operation and maximize economic benefits.
