Jumping stroke 85mm rammer

Types of jumping stroke 85mm rammers

Jumping stroke 85mm rammer is a compact piece of machinery used for soil consolidation or compaction. It consists of several types and can be powered either electrically or by gasoline.

• Pneumatic jumping jolt rammer

  The pneumatic jolt rammer operates largely on the same principle as an air pogo stick. Compressed air powers a piston inside the rammer, which then strikes the ground at regular intervals. This type of jolt rammer is excellent for compacting soils in trenches or confined spaces. Because it operates with air pressure, it's ideal for places where flamethrowers could pose a risk. However, it does require a separate air compressor to function, which can limit mobility.

• Electric jumping jolt rammer

  An electric jump jolt rammer relies on electricity to power a motor, which in turn controls the piston movement. Electric jolt rammers are often quieter and produce fewer emissions, making them suitable for indoor or urban work sites. Nonetheless, the electric power they receive limits their battery or cable connection ranges. Thus, they may not be ideal for large-scale outdoor projects where power supply isn't readily available.

• Gasoline-powered jumping jolt rammer

  Similar to regular gasoline-powered tampers, the gasoline-powered jump jolt rammer utilizes a gasoline engine to drive its piston. This type offers great power and versatility, suitable for various outdoor soil compaction tasks. Its independence from the power grid makes it applicable in places without electricity. However, factors like engine noise, exhaust emissions, and fuel consumption should be considered during selection. These may be more suited for large construction sites versus small-scale ones.

Specifications and maintenance of jumping stroke 85mm rammer

Specifications

The specifications of a jumping jack rammer can vary accordingly. The following list explores some of the typical specifications of this ramming machine:

• Weight: The weight of the jumping rammer can be around 75 to 100 kg. However, mini models can also be less than 75 kg in weight.
• Engine: The type or model of engine used in the jumping jack rammer can impact its overall weight and functionality. Some rammers utilize a gasoline-powered engine, while others are powered by diesel fuel. The engine size may also vary, but many jumping jacks feature a 13 HP air-cooled engine.
• Packing dimension: A typical packing dimension of the jumping jack compactor can be around 125x55x79cm.
• Excitation force: The excitation force of a jumping jack rammer refers to the mechanical force responsible for driving the rammer's foot into the ground. This force is generated by the rotation of eccentric weights and is a critical factor in determining the compaction of soil or other materials. The excitation force can vary depending on the model being used but is usually between 12 to 17 kN.
• Operating speed: The operating speed of a jumping jack rammer refers to the pace at which the machine can be moved or used during compaction. Depending on the model and situation, this speed can range from 12 to 20 m/min.

Maintenance

Regular maintenance of the 85mm jumping stroke rammer is really important to ensure its smooth, efficient, and safe operation. Furthermore, it can help to extend the machine's lifespan. Some crucial maintenance tips are as follows:

• Daily maintenance checks: Operators must make it a routine to conduct daily checks and servicing of the jumping jack after every use. This includes checking the engine oil, water, and fuel levels. They should also check the rammers for any loose parts, damage, and necessary adjustments. Addressing issues right after they are discovered can prevent more significant problems down the road.
• Periodic servicing: Depending on the usage frequency, businesses may have to do regular jump rammer service every few weeks or monthly, quarterly, or yearly. This includes replacing the engine's air filter, oil filter, and fuel filter. Importing the jumping jack's eccentric shaft and bearing with grease is also necessary to avoid excessive wear from friction.
• Keep it clean: It's essential always to keep the jumping ramming machine clean. Remove any soil, dirt, or debris from its parts after use, especially from the cooling fins and engine area. This will prevent overheating and allow the equipment to function optimally.

Applications of jumping stroke 85mm rammers

Jumping jack rammers are commonly used in the construction industry to compact soil. However, its applications are not limited to backfill and trench issues. Here are some more applications of jumping jack rammers.

• The foundation of a building is crucial for its structural integrity: a solid foundation helps secure the whole building. Soil compaction with a jumping jack rammer ensures that the foundation is stable and won't settle or deform over time.
• Heaving of pavement or unpaved roads can be mitigated by proper soil compaction under the pavement. Compacting the soil with a jumping jack rammer increases the load-bearing capacity of the soil, thereby extending the life of the pavement.
• Soil settlement is a risk that can be reduced by compacting the fill material in over-excavated areas. Compaction with a jumping jack rammer reduces the risk of settlement when load compaction is applied.
• Installation of underground utilities, such as water and sewer pipes, electrical conduits, and fiber optic cables, can benefit from proper soil compaction around them to prevent settling and maintain the integrity of the utility lines.
• Landfills and solid waste management facilities also require soil compaction to minimize waste volume and prevent settling over time.
• Compacting soil in landscaping projects and parks can help create stable and robust landscapes. Furthermore, stator compactors can also be used to make walking paths and patios. This includes desire lines in parks and the base of the patio or pathways.
• Repairing sinkholes and caves can also be done using a jumping jack rammer. By filling the voids and compacting the surrounding soil, the stability of the area can be improved.
• Ice ventures in colder regions may benefit from compaction to increase the ice thickness and improve load-bearing capacity to create safe trails and transportation routes on frozen water bodies.
• Industrial flooring that requires high load-bearing capacity can be achieved by using a jumping jack rammer to compact the soil or sub-base before laying the floor. The risk of deformation of the industrial floor will be reduced if the soil or base is compacted with a rammer.
• Cone penetration tests and other in-situ soil tests can be conducted after soil compaction to determine soil characteristics and behavior under load.

How to choose jumping stroke 85mm rammer

The following factors are helpful for buyers to consider when choosing a proper jumping jack compactor for their construction projects.

• Project requirements analysis

  At first, set up the project requirements like soil type, compaction depth, and desirable compaction force. Then, based on the project requirement analysis, the grounding material can be determined, such as granulated ground, cohesive soil, or asphalt. Besides, the compaction depth and the desired compacting force should also be taken into account. For example, lighter footing work can use smaller proof rollers, but for larger projects, heavier rollers or steel drum rollers should be used.

• Types of jumpers and their advantages

  Weigh all the available options. Gas-powered jump rammers are best for outdoor jobs because they provide consistent power and are easy to refuel. Electric jump rammers shine in environmental sensitivity, being quiet and producing no emissions, yet tethered by cable connectivity. Hydraulic variants offer exceptional versatility, handling a wide range of soil types with adjustable compaction settings; however, they are also more expensive to purchase and maintain. Diesel-powered jump rammers excel in fuel efficiency and power output but come with a higher upfront cost compared to gasoline models. The buyer's project scenario will determine which type is most suitable.

• Checking key features

  Choosing the right jumping jack also involves considering the details. Look for robust build quality to withstand the rigors of compaction work. An ergonomic design reduces operator fatigue during extended use. A clear and comprehensive user manual ensures proper operation and maintenance. The availability of spare parts and skilled service personnel nearby minimizes downtime. Also, check the warranty period and coverage.
