Types of Walk Behind Compactors

There are several types of walk behind compactors, each suited for different tasks and ground conditions. Understanding these types can help you select the right equipment for your needs.

Plate Compactors

Definition and Function

Plate compactors consist of a heavy steel plate attached to the bottom of the machine, which vibrates to compact the ground. They are widely used for their efficiency and ease of use.

Types of Plate Compactors

Single-Plate Compactors: Ideal for smaller jobs and tight spaces, single-plate compactors are lightweight and easy to maneuver.

Reversible Plate Compactors: These machines can move forward and backward, making them suitable for larger areas and providing more efficient compaction.

High-Frequency Plate Compactors: Designed for granular soils and asphalt, high-frequency compactors offer rapid vibrations for efficient compaction.

Common Applications

Plate compactors are commonly used in driveway construction, landscaping, and small-scale paving projects.

Rammer Compactors

Definition and Function

Rammer compactors, also known as Tamping Rammers or jumping jack tampers, use a percussive force to compact soil. They are particularly effective on cohesive soils.

Types of Rammer Compactors

Upright Rammers: These are the most common type and are excellent for general-purpose compaction.

Trench Rammers: Specifically designed for trench work, these rammers are narrower and can fit into tight spaces.

Common Applications

Rammer compactors are ideal for compacting cohesive soils, such as clay, and are commonly used in trench and foundation work.

Walk Behind Roller Compactors

Definition and Function

Road roller compactors feature one or more cylindrical drums that roll over the ground, applying static or vibratory pressure to compact it.

Types of Walk Behind Roller Compactors

Single Drum Rollers: Suitable for granular and mixed soils, single drum rollers are effective for small to medium-sized areas.

Double Drum Rollers: With drums at both the front and back, these rollers offer excellent maneuverability and efficient compaction.

Common Applications

These compactors are frequently used in road construction, parking lots, and large landscaping projects.

Sheepsfoot Compactors

Definition and Function

Sheepsfoot compactors have drum surfaces covered with lugs or feet, resembling a sheep’s foot. These feet penetrate and compact the soil.

Unique Features

The lugs create high contact pressure, making these compactors ideal for dense and cohesive soils.

Common Applications

Sheepsfoot compactors are commonly used for deep compaction of clay and other cohesive soils in large construction projects.

Vibratory Compactors

Definition and Function

Vibratory compactors use vibration to reduce air voids in the soil, increasing its density.

Types of Vibratory Compactors

These compactors can come in plate or roller forms, each offering different levels of vibration intensity and suitability for various soils.

Common Applications

Vibratory compactors are used for a wide range of applications, including road construction, foundations, and large paving projects.

Pneumatic Rollers

Definition and Function

Pneumatic rollers use a series of rubber tires to apply static and kneading pressure to compact the ground.

Unique Features

The rubber tires provide a smooth finish and are adjustable for varying ground conditions.

Common Applications

Pneumatic rollers are ideal for finishing asphalt surfaces and for use on soft and uneven ground.
