Electric vibrating plate - highly specialized equipment for ramming and compaction of gravel, sand, crushed stone and other materials, as well as various types of soil. Such machines have a simple structure. Manufacturers offer different types of vibrating units that differ in appearance and technical characteristics.

Description

All modifications of vibrating plates have a similar device. Their design includes a number of elements. Let's list them.

• Working (base) plate . This is the working body of the unit, called the sole. For the manufacture of the platform, sheet steel with a thickness of at least 8 mm, cast iron or other heavy metals is used. The plate should be distinguished by its weight, convenient for work dimensions of the working surface and wear resistance. On most models, the outsole has additional stiffening ribs and rounded edges for a smooth ride.
• Vibrator (eccentric) . Vibration generating device. It is made in the form of a cylinder, inside which there is a shaft with an offset center of gravity.
• Frame with electric motor . The overwhelming majority of models of electric vibrating plates are equipped with motors from 0.25 to 1.5 kW. The motor pulley is connected by a V-belt drive to the eccentric shaft. The vibration motor is mounted on a motor frame equipped with a shock absorption system.
• Drove . This is the handle of the unit, with which the operator controls the equipment.

The principle of operation of the vibrating plate is simple - when the engine is started, the vibrator transforms the rotational motions of the motor into vibrational ones, which are transmitted to the base plate. Due to the quick jerking movements of the base plate, the soil is compacted.

Advantages and disadvantages

Electric vibrating plates are rather compact and technically uncomplicated equipment, which is easy to operate. This technique is maneuverable - it can be used in places where the use of bulky heavy equipment is impractical . The 220 V electric vibrating plate is much quieter when compared to diesel or gasoline versions. Due to this feature, it does not have a negative effect on the hearing organs during short-term use.

However, for long-term use, it is recommended to use special headphones or earplugs . Vibratory plates with an electric motor do not emit harmful exhaust gases, due to which they can be used even in closed rooms, as well as where harmful emissions and noise are unacceptable.

Other advantages of vibrating electrical technology include:

• unpretentious maintenance;
• affordable cost (pressing equipment operating from a 220 V network is several times cheaper than gasoline and diesel analogues);
• durability.

To increase the level of operator's safety, the equipment is equipped with specialized protective devices that reduce the risk of electric shock to a person. Electric vibrating plates also have some disadvantages. These include: low performance and dependence on the electrical network. Due to attachment to the source of energy, they are limited in use. For example, they cannot be used where there is no electricity or there are frequent interruptions in its supply.

In addition, electric models of vibrating plates are inconvenient for fast movement from one construction site to another. For 380 V units, in the absence of an outlet with such a voltage, you will have to buy a special converter.

Areas of use

Vibration plates are often used in the arrangement of the local area, summer cottage, in the preparation of the area for laying sidewalks, garden paths and other objects. It is indispensable for soil compaction when building agricultural facilities, road bases, and landscaping. This technique is used in private households by home craftsmen, utilities and small construction companies.

Vibratory plates are often used for laying tiles when arranging an area near entrances, production sites, parking lots, as well as facilities for the equipment of which it is impractical to hire expensive heavy-weight rollers. They are often used for compacting the soil layer during patching of roads.

Species overview

Vibrating electric platforms are classified according to their mass

• Ultralight units (up to 75 kg) , which are recommended for use for landscaping. They can be used to compact soil up to 150 mm thick.
• Lightweight models (75 to 90 kg) designed for compaction of soil to a depth of 200 to 250 mm.
• Medium-weight modifications (from 90 to 140 kg) , capable of compacting the layer up to 300 mm.

In addition, vibratory plates are classified according to the type of movement.

Reversible

Units included in this group have the ability to move forward and backward. Such models are most often massive (weigh more than 100 kg). This technique is convenient to use when compacting soil on horizontal surfaces, as well as in trenches and ravines. Reversible vibratory plates are highly maneuverable.

Irreversible

This includes straight (one-way) models that translate in only one direction. They are intended for use in places where it is possible to turn the machine. In contrast to the reversible modifications, the linear models are more compact, have less weight and greater centrifugal force.

They effectively compact any type of soil and surface.

Nuances of choice

When buying a vibrating machine, it is recommended to pay attention to several important criteria

• Equipment weight . The heavier the unit, the deeper it compresses the soil. However, massive and weighty vehicles are harder to handle. For private use, it is best to look at lightweight models, and for industrial use - to heavyweight variations from 100 kg.
• Base frame size . This parameter determines how much area can be compacted in 1 run. On the other hand, the more the sole area is, the less quality the tamping will be.
• Vibration motor power . It will determine the performance of the equipment.
• Additional options . One of the useful functions that simplify the work is the ability to adjust the frequency of oscillations. Materials with fine grain are recommended to be processed at high vibration rates, and coarse-grained at lower frequencies.
• Heavy equipment should be capable of both forward and reverse travel . This greatly facilitates the operation of massive equipment.

When buying a soil pressing machine, you need to decide on the manufacturer. The technique of domestic brands will be cheaper than imported counterparts. In order for the equipment to serve as long as possible, you should refuse to purchase units of dubious production.

How to use?

Quality vibration technology is unlikely to fail prematurely if used correctly. It is imperative to follow the factory recommendations for its operation. Before starting work, you need to change into work clothes (there is a special suit). In the process of work, personal protective equipment should be used:

• earplugs or ear muffs;
• respirator (in case of dust formation during the compaction of the material).

Before using the vibrating plate, you need to prepare the treated area: remove large stones, working tools, electrical cables and other foreign objects. When working, it is important to watch that the unit wire does not get under the sole. Otherwise, it may be damaged.

If you need to install paving slabs, it is recommended to use a rubber mat . It is designed to reduce mechanical stress on fragile building materials. When using vibratory plates, the operator should take breaks every half hour of work. Prolonged contact with vibrating technology causes serious harm to health. During the working day, it is advisable to change more often with a partner in the control of the unit. While the partner is working, you can do other things that are not related to the direct compaction of the soil.

Compliance with these simple rules will extend the durability of the equipment and preserve the health of the operator.
