By the end of 2022，Hummer has upgraded 10 products of its small roller series.。All models are equipped with Kubota engines，Meet the fourth national emission standard。In addition，Front wasp-waisted construction gives the roller excellent visibility。Three-point articulation also ensures excellent driving stability and handling comfort。
For numerous asphalt constructions as well as horticultural and landscape works，Hummer offers a wide range of options.，Users can find the right equipment to meet their needs.。
These 10 new models are aimed at the Chinese market.（HD 18 VV, HD 20 VV, HD 30 VV, HD 30 VT, HD 35 VV, HD 35 VT, HD 35 VO, HD 50 VV, HD 50 VT And HD 50 VO：Self-weight 1.8 t To 5 t），Meets China's new Phase IV emission standards，It is manufactured by Wittgen Langfang Factory in China.。
Drum width coverage 0.8 m – 1.38 m，Tailored to meet local market needs。In terms of compaction technology，Available with two vibratory drum (VV)，Models with one vibrating wheel and one oscillating wheel (VO)，And models with one vibrating steel wheel and one set of tires (VT)。
01
Wasp waist design for excellent visibility
Ingenious design of engine housing，Nsures a clear view in front of the machine。And，Thanks to the typical wasp-waist structure design of Hummer，The operator can see the steel wheel and the surrounding construction environment at a glance.。
02
Uniform weight distribution
Three-point articulated mechanism is the key factor to achieve high-quality compaction results.。It not only ensures an even distribution of weight between the front and rear axles of the machine，It also gives the machine a smaller turning radius and a high degree of driving comfort。Benefit from an articulated mechanism and a low center of gravity，HD Series Small Rollers avoid the risk of tipping even in narrow areas。
03
Large diameter steel wheels to achieve high pressure strength
HD High static line pressure of series small Road Roller，And that excite force is large，Therefore, it has strong compaction performance.。The large-diameter steel wheel can also effectively prevent the formation of road surface clogging or wrinkles.，Thereby ensuring excellent compaction quality.。When compaction is carried out against curbs or walls，HD Series of small rollers can easily cope with。
For example，HD 18 and HD 20 models can achieve the standard 72 mm And 70 mm The magnitude of the wrong wheel，And a steel wheel single-side suspension structure is adopted.，Parts on both sides are arranged within the working width range，Easily realize double-side zero-clearance welt compaction，Therefore, welt compaction along walls or other obstructions is not a problem。
In addition，Both machines are available as an option without a staggered wheel design。HD 30 until HD 50 steel wheels for up to 50 mm The magnitude of the wrong wheel。Folding Scrapers are standard on all models。
04
Reliable Sprinkler system
Sprinkler systems are designed for high quality compaction and high construction efficiency。HD Sprinkler system for series small Road Roller，Three-stage filtration design is adopted.，Includes a self-cleaning water cartridge、Filler element and sprinkler system front element。So，Nozzles and spray bars are ready for easy up。During compaction，The operator can control the amount of sprinkling on the dashboard.。When necessary，The amount of water sprinkled can also be increased by means of a foot switch。
05
Simple and intuitive control of the whole machine
All control elements are clearly identified by clear symbols，The function is clear at a glance。All important construction information is displayed on the display，No need for any text display。So，Even a novice，It is also immediately clear how to operate the roller.，Ensure overall construction safety。
06
Options for a wide range of applications
Hummer also offers a variety of options for customers.。For example，Trimming and pressing device with suitable pressing roller and cutting wheel、LED Working headlights、LED Rotary warning light or plastic protective canopy。
07
Easy to transport，High maintenance efficiency
HD Series of small rollers HD 18, HD 20, HD 30 and HD 35 The machine can be easily loaded via the lifting point in the centre of the handrail。Even small Vehicle/ 'target='_blank' style='color:blue;'>Transport Vehicles can be easily loaded。The whole machine transportation process is time-saving and convenient.。The Hummer Roller is not only simple to operate，Maintenance is also very efficient。
For example，The center drain is located at the lowest point of the machine，Complete emptying of the water tank from the rear of the roller with a simple manual operation。In addition，The self-cleaning water filter can be checked in seconds.。All maintenance points are concentrated on the machine sides，Large opening engine cover is convenient for the operator to check，Other daily inspections can be easily completed without any tools。
