HT35 tailless small excavator

In the construction scenarios where space is limited, such as urban municipal renovations, agricultural and forestry land reclamation, park infrastructure construction, and interior demolition, the compact and flexible micro excavators have become a must-have for engineering projects. Hightop has been deeply engaged in the research and development of small construction machinery and has launched the HT35 3.5-ton tailless excavator. Relying on mature complete machine configurations and user-friendly structural designs, it balances operational efficiency, usage costs, and driving experience, and is suitable for various construction needs, becoming a commonly used construction equipment for small-scale engineering practitioners.

The power configuration is the foundation for the stable operation of construction machinery. The Hightop HT35 is equipped with a Kubota Euro IV electronic control engine with a rated power of 18.5kW. After power adjustment and optimization, its fuel consumption control performance is excellent. The entire machine is equipped with a 50L fuel tank. Compared to conventional models of the same specification, the continuous operation time has been increased, reducing the interruption of construction due to mid-job refueling. It can also ensure the continuity of operations in remote and rural areas, helping users control daily operating expenses from the perspective of fuel expenditure.

The body adopts a classic tailless design. The turning radius of the equipment at the rear end is 885mm. Combined with the original factory standard large arm side swing structure, it is a practical configuration for tunnel construction, basement excavation, and wall-side trenching. In narrow alleys and greenhouses for land preparation, the equipment can operate close to the wall. The turning and loading/unloading operations are flexible, breaking through the traditional limitations of small excavators' turning radius and usage shortcomings, and adapting to various compact construction environments. The hydraulic system uses a load-sensitive main valve combined with a slanted disc variable pump. The hydraulic feedback speed is stable, and the connection between multiple compound actions such as digging, loading/unloading, and leveling is smooth. The energy utilization efficiency of the entire machine is optimized, and one machine can complete various operations such as digging ditches, crushing stones, material grasping, and site leveling.

The overall operation parameters are adapted to the daily engineering requirements. The equipment can dig to a depth of 3.1 meters and a height of 4.93 meters. The bucket's digging force is 30.4 kN. A standard 0.12 m³ capacity bucket is equipped. The front bulldozer blade can not only tidy up the site and collect scattered materials but also support the machine's body on the ground during operation, improving the stability of the entire machine's operation. It has better stability for construction on mountainous and soft land.

The equipment has been optimized specifically for post-maintenance purposes. The entire machine features a side-opening protective casing combined with a modular component layout. The hydraulic valve group is placed externally. The various maintenance points are arranged neatly. Compared to traditional models, the time required for routine oil changes and component maintenance has been significantly reduced. There is no need to dismantle the entire machine for component disassembly and inspection, thereby reducing the maintenance time and labor costs of the equipment.

From the perspective of drivers and passengers, it is based on the actual needs of the operators. The spacious driver's cabin is equipped with a heating and cooling air conditioning system. The body sealing and noise reduction technology is well-developed. Combined with the integrated steel frame body and shock absorption structure, it is not easy to get tired during long-term continuous operation, and the protective structure further improves the safety coefficient of construction.

From rural farmland reclamation to urban old residential area renovation, from indoor civil engineering to small-scale garden construction, the HT35 tailless small excavator from Hightop boasts low energy consumption, durability, flexibility, and simple maintenance. It covers most medium and small-scale construction scenarios. Based on practical needs, it creates practical equipment, and with reliable quality, it helps projects be smoothly implemented. It is a worthy model for on-site investigation and purchase among 3.5-ton level excavators.
