About soil tamper rammer

Types of soil tamper rammer

A soil tamper rammer is an indispensable piece of compacting equipment used mainly for horizontal and confined area applications. It works by repeatedly striking the same area to compact loose material. Its shape resembles a large hammer or a fat cylinder with a handle. Based on the power source, soil tampers can be divided into the following five categories.

  • Pneumatic Tamping Rammer

    This rammer runs on compressed air and is sometimes called an air jack or air hammer. Its handling can be easy or difficult, depending on the use of aids like hoist straps and lanyards. The tool is widely used in road and utility work to compact soil in trenches. MacPherson recommends this tool for compacting granular soil but not for cohesive soil or mixed soil with a high clay content.

  • Gas-Powered Tamping Rammer

    Also referred to as a tamping stick or gas jack, this type of soil tamper uses gasoline as its fuel. Due to the lightweight engines it employs, this tamping tool is more portable than others. While some have an integral fuel tank, others use a fuel line connected to a remote tank. This tool works great for utility and general excavation applications.

  • Electric Rammer Tamps

    Also known as the electric self-contained tamping rammer, this tool is powered by a rechargeable battery. It provides the advantage of having no exhaust and significantly less noise while working compared to its gasoline-powered counterpart. Furthermore, it requires no fuel or air compressor to operate. While the battery life may be limited, it serves as a tamper that can smoothly deal with trench compaction in utility work. It can also be used in sites that require strict environmental standards.

  • Vibratory Soil Compactor

    When the term 'tamping rammer' comes up, many people often think about the 'vibratory soil compactor.' This is because it is the most commonly used soil compactor tool. It uses the principle of vibration to densely pack soil, making it ideal for foundational work. This compactor can be easily maneuvered around, intensifying its compacting action.

  • Plate Compactor

    Like the heavies, vibratory plates are often integrated into walk-behind compactors. They comprise a sizeable electromotive unit placed on a base plate. Plate compactors excel in creating flat surfaces and performing tasks like patching holes and creating base layers for foundations. While smaller, the limited weights and forces of the electric variants hinder their use in more extensive, more demanding projects.

Specification and Maintenance

Specifications

  • Weight: Soil rammers usually weigh between 10kg and 30kg (22 to approximately 66 lbs). The heavier types are better for compacting loose soils and larger areas. Lighter models are more portable for digging trenches and smaller compacting tasks.
  • Bases: The base plate size affects how much area can be compacted per strike. Typical diameters include 30cm to 40cm (12 to 16 inches). Flat, circular bases work well for most soils. Squared-off bases provide better corner compaction. Larger base sizes are suited for bitumen and concrete.
  • Engine: Soil tampers use either petrol or diesel engines. Common petrol engines are 5 HP, while diesel engines may be around 5.5 HP. Higher horsepower generates more tamping force. Single-cylinder engines provide sufficient power.
  • Strokes per minute: This refers how many times the rammer strikes the ground per minute. It usually ranges from 2,400 to 3,500. Higher striking frequencies compact soil more efficiently.
  • Vibration: Compactor rammers transmit vibrations to the operator's hands. This is usually measured in m/s2. High vib levels can be hazardous. Maintaining dampers within limits  shergau AVH (3.9) is important for operator safety

Maintenance tips

  • Periodic inspection and cleaning are critical tasks for ram soil tampers. At least once a week or after every 4- 5 hours of operation, inspect the machine and keep it clean.
  • Use the right fuel and oil to avoid damaging engine parts.
  • Keep loose guards and body parts tightened to avoid accidents and hazards.
  • When using the rammer, make sure it is horizontal. This is important for oil circulation and combustion chamber performance.
  • Store the machine indoors or use a cover to protect it from rain and dust.

Application scenarios of soil tamper rammer

  • Foundation or footing construction:

    A soil tamper is used to compact the soil when laying the foundation for a building or structure. Ensuring the stability of the foundations by compacting the soil helps to reduce future settlement.

  • Trenches and backfill compaction:

    Soil tammers are used to compact the soil after excavation or when laying pipes or cables. Also, compacting the soil in trenches reduces the possibility of future settlement and provides stability to the surrounding soil and structures.

  • Edge and slope restraint compaction:

    Soil tampers are used to compact the soil and create a slope or edge when digging or excavating. Soil tamper rammers are ideal for compacting soil in hard-to-reach places and creating stable slopes and edges.

  • Landscaping and patio or driveway construction:

    Soil tampers can be used in landscaping and when constructing patios or driveways. A soil tamper helps to create a stable and even surface ideal for these applications.

  • Site preparation for construction:

    Soil tampers are used to prepare a construction site by compacting the soil. Soil tampers help to create a stable and level base ideal for subsequent construction activities.

  • Asphalt and road repair:

    When carrying out road repairs or working on asphalt surfaces, soil tampers can be employed to compact the soil. Soil tampers ensure stability and compaction in road repair and asphalt work.

How to choose soil tamper rammer

Several factors of soil compactor rammers should be considered when deciding which ones to stock for reselling.

  • Popularity of types of soil tampers among users

    When deciding which type of soil tamper to stock for resale, it is important to consider the different kinds of soil tampers available and the specific applications for which they are used. For instance, handheld tampers are widely used due to their applicability to various tasks, such as laying sidewalks and working on landscaping projects. Resellers should consider stocking handheld tampers to cater to their wide usage. Moreover, resellers should consider the popularity of gas-powered soil tampers compared to other types. Gas-powered tampers are popular due to their versatility of use outdoors. Electric-powered tampers are ideal for indoor use, and pneumatic tampers are used in large-scale operations. Resellers should consider the popularity of each soil tamper type and stock up accordingly.

  • Quality of the tamping machines

    When selecting soil tampers for resale, resellers should consider the quality of the machines chosen. Many construction workers often choose soil tampers with up-to-par features. For instance, the quality of the base plate varies from one soil tamper to another. Resellers should choose tamping machines with durable base plates that can withstand various working conditions. Additionally, resellers should opt for soil tampers with dependable engines that have optimal performance. Moreover, resellers should choose tampers with ergonomic features to offer utmost ease to workers. Factors such as vibration dampening systems and comfortable handles are interchangeable features of quality tampering machines.

  • Pricing of the tamping machines

    Resellers should consider the prices of different soil tamping machines and their affordability to potential customers. Many customers are willing to pay extra price for a quality machine with up-to-par features. However, some budget-conscious customers may consider renting rather than purchasing a soil tamper. Resellers should stock up on different types of machines that suit both ends of the spectrum. For instance, premium models can be stocked for commercial developers who have larger projects and deeper financial capabilities. Additionally, more affordable models can be opted for to cater to small-scale developers, landscapers, and DIY homeowners.

Soil tamper rammer FAQ
