The HEKING HK420ZL is a 42-ton clamshell bucket excavator developed for professional material handling work requiring a large machine platform, substantial bucket capacity and extended working range.
The machine has a standard 3 m³ bucket capacity and reaches a maximum digging radius of 10,888 mm, with a maximum dumping height of 8,460 mm. These specifications make the HK420ZL suitable for projects where material needs to be excavated, lifted, handled and discharged within a relatively large working envelope.
For B2B buyers, the HK420ZL provides a defined heavy-duty machine configuration rather than a general-purpose excavator specification. Its 42,000 kg operating weight, Cummins C8.3 engine, high-flow hydraulic system and 3 m³ standard bucket are key parameters for evaluating its suitability for industrial material handling requirements.
The product is manufactured by Anhui Hekuang Environmental Technology Co., Ltd. under the HEKING brand. Hekuang is an export-oriented machinery manufacturer based in Hefei, China, with a production base covering more than 100,000 square meters and a team of 125 employees, including 42 technical specialists and 10 senior professional engineers.
The HK420ZL uses a Cummins C8.3 engine with six cylinders and an inter-cooled turbo configuration. The rated engine power is 186 kW at 2,200 rpm, while maximum torque is specified as 1,158 N·m at 1,500 rpm.
The engine configuration provides the power source for the machine's hydraulic and travel systems. For procurement teams, the stated engine model, rated power and torque are useful reference points when reviewing equipment specifications and planning operating requirements.
The hydraulic system uses a variable plunger pump configuration with a maximum flow of 2 × 260 L/min and a working pressure of 32 MPa.
The hydraulic specification is particularly relevant when evaluating a clamshell bucket excavator because hydraulic output affects the operation of the machine's working equipment, travel system and slewing functions. The HK420ZL specification provides the stated hydraulic flow and pressure figures for technical comparison and project evaluation.
The HK420ZL has a specified slew speed of 11 rpm. Maximum travel speed is 5.2 km/h in the high-speed range and 3.3 km/h in the low-speed range.
The machine's listed tractive effort is 379 kN, with a gradeability specification of 0.7. Ground pressure is stated as 67.6 kPa.
These figures can be used by buyers to assess the machine's travel and positioning characteristics in relation to the intended worksite.
The HK420ZL provides a maximum digging radius of 10,888 mm and a maximum dumping height of 8,460 mm. Maximum digging depth is 5,636 mm.
The specification also lists a minimum front slewing radius of 4,717 mm, a minimum rear slewing radius of 3,485 mm, and a maximum digging height of 2,617 mm.
The listed working range should be evaluated together with the actual material handling process, site layout and required discharge position rather than considered independently.
The HK420ZL is intended for professional material handling work where a heavy-duty excavator platform and clamshell bucket configuration are required.
Typical application evaluation can include:
Material handling: Handling and transferring bulk materials where the 3 m³ standard bucket capacity is applicable.
Industrial handling operations: Projects requiring a 42-ton-class machine with a substantial hydraulic system and working range.
Large-scale handling sites: Applications where the machine's 10.888 m maximum digging radius and 8.460 m maximum dumping height are relevant to the site layout.
Heavy-duty equipment operations: Projects requiring a machine with 42,000 kg operating weight and 186 kW engine power.
Actual application suitability should be confirmed according to the material type, working method, bucket configuration, site conditions and required production process.
The HK420ZL is specified with a 3 m³ standard bucket capacity, providing a substantial working-tool configuration for material handling operations where this capacity is appropriate.
With an operating weight of 42,000 kg, the HK420ZL is positioned in a heavy-duty excavator class for professional industrial applications.
The machine uses a Cummins C8.3 six-cylinder, inter-cooled turbo engine rated at 186 kW at 2,200 rpm.
The hydraulic system has a maximum flow of 2 × 260 L/min and a working pressure of 32 MPa, providing clearly defined hydraulic parameters for technical evaluation.
A maximum digging radius of 10,888 mm and maximum dumping height of 8,460 mm give buyers specific working-range parameters for assessing site requirements.
The HK420ZL is specified with a 650 L fuel tank and a 350 L hydraulic tank, useful reference points for project planning and machine configuration assessment.
