Hand-held rammers and vibratory plates are mainly used in confined areas. The running properties have to be right and compaction and system control is increasingly in demand.

If the subsoil has to be compacted in a cramped environment, for example in buildings or when digging a trench, a hand-held vibration tamper or vibration plate is usually used. In the tamper, a multi-spring vibration system ensures an upward and downward movement, which is transmitted to a plate attached to the lower end of the device. This lifts a few centimeters from the ground.
The effect of vibration plates (vibrating plates) is based on centrifugal forces, which are caused by several shafts with integrated imbalances. With each revolution of the shaft, these centrifugal forces lift the plate minimally from the ground and then let it fall again. The demands on such machines are enormous. The efficiency and running properties have to be right, and compaction and system control is increasingly in demand. In addition, the requirements for the protection of construction workers (for example with regard to hand-arm vibrations) are becoming more and more demanding.
Wladimir Drisner (Product Manager at Ammann Verdichtung GmbH) replied to the question of which technical trends the hand-held soil compactors will face in the future: "In the coming years, electronics will prevail on vibratory plates in the form of measuring systems for the compaction achieved . The use of various software, such as telematics, will also be increased for hand-held soil compactors. Integrated theft protection and a system for locating stolen machines using location systems are current topics that will establish themselves on the market in the future. "
Oliver Kolmar (Product Manager Compaction Technology at Wacker Neuson) said: "The machines from Wacker Neuson must offer comfort and safety." In other words, in addition to efficiency, the focus is on the least possible stress for the user. For example, in the field of remote-controlled compaction equipment, which completely protects the operator from hand-arm vibrations, emissions, noise and dust, an additional safety factor is the infrared technology of the remote control, explains the product manager. This ensures that the device stops automatically if it moves too close to the operator or if the visual contact between operator and device is interrupted.

Ammann

Ammann Verdichtung GmbH produces and sells high-quality compaction equipment for professional use. The product portfolio includes rammers from 62 to 83 kilograms, forward vibrating plates from 54 to 123 kilograms, as well as reversible vibrating plates up to 737 kilograms and a remote-controlled, steerable, fully hydraulic vibrating plate weighing 747 kilograms. In addition, Ammann has established a hand-operated, fully hydraulic roller with two amplitudes on the market. Special properties of the rammers are, according to the factory specifications, the low center of gravity of the engine and the air filter system with only one air filter, which is arranged horizontally. The continuously height-adjustable guide handle is also an advantage.
With the forward-running machines, the vibration-reduced drawbar offers the possibility of using the machine without the necessary documentation of the working hours. The APH 5030, 6530, 100-20 models are equipped with a 3-wave exciter. At the same time, it is possible to measure the compaction achieved during the compaction process with the ACEforce technology. Due to the automatic regulation of the amplitude and the frequency, the machine always compresses with the optimal parameters, according to the company.

MTM-Spindler & Schmid

MTM-Spindler & Schmid GmbH, based in Heroldstatt, has been developing, producing and selling pneumatically operated special machines for various areas of application since 1990. The range also includes three compressor models. All devices run with an operating pressure of seven bar and are, according to the factory specifications, ideal for compacting small areas in narrow construction pits, as well as for processing rammed earth.
The first model is the DLS compressed air rammer. It weighs around 20 kilograms and uses around 700 liters of air per minute. The number of strokes is between 700 and 1,100 per minute. The second model in the range is the Turbo Terra Rammer I. It is used to compact small areas of clay, crushed stone, sand, gravel, bitumen and tar. It is also used to compact repair work with fine bitumen covering, manhole cover repairs, as well as foundation areas and ponds.

Ravi construction and rental equipment

The company Ravi Bau- und Mietgeräte GmbH (Radeberg) produces vibration technology for compacting concrete, soil and bulk material. The range includes internal vibrators, vibration plates (forward and reverse), rammers and track tampers. The vibratory plates range from compact devices with low operating weight and easy portability to vibratory plates with forward and reverse motion and high performance. Both electric, gasoline and diesel engines are installed.
The RVP 12 ED / EE vibration plate is a device with an electric motor. It is mainly used in closed rooms and wherever internal combustion engines are not possible. The motor output is 1.5 kW, the panel dimensions are 650 x 350 millimeters. The weight is 78 kilograms. 18 to 22 meters are processed per minute. The depth effect is less than 35 centimeters. The vibration plate RVP 16 BH is equipped with a 4-stroke petrol engine from Honda with 2.9 kW. In addition to compacting soil and bulk material, it is particularly suitable for asphalt and bitumen. The panel dimensions and weight are identical to the RVP 12 ED / EE. The machine reaches a depth of up to 40 centimeters.

Wacker Neuson

Wacker Neuson has a wide range of compaction equipment, including vibratory rammers, vibratory plates and rollers. The company sells its products in Germany through direct and dealer sales. Among other things, Wacker Neuson offers a range of rammers with a two-stroke engine. The rammers are equipped with the WM 80 engine developed by Wacker Neuson, which, according to the factory, falls below all current emission limit values ​​known for the future. According to Oliver Kolmar (Compression Technology Product Manager at Wacker Neuson), the engine is characterized by low consumption, excellent starting behavior, high-quality and long-lasting engine components and can also be used in an inclined position.
The two-stroke rammers of the i-series offer additional work relief with separate oil lubrication. With two separate tanks for fuel and two-stroke oil, premixing is no longer necessary. The liquids are poured in separately. The patented oil lubrication system automatically creates the correct mixing ratio.

Weber machine technology

Weber Maschinentechnik GmbH is a medium-sized company with headquarters in Bad Laasphe. In addition to the hand-held soil and asphalt compactors (vibrating plates, vibratory rammers, plates, rollers), floor sawing machines and concrete compactors complete the range.
The latest model is the further development of the CR8 from the Weber MT upper class. The CR 8 has a centrifugal force of 75 kN and a weight of around 600 kilograms. The CR 9 served as a model for the design and technical details. All-round cladding and the sturdy frame protect the Hatz 1D81Z diesel engine used. The height-adjustable hand guide bar with a rubber-coated handle should enable fatigue-free work. The soil compactor is available with the Compatrol® compaction control. This is available in the model variants CCD (compaction control) and MSM (compaction control with additional machine and service management).
