Item wheel wash water recycling 'Aquador' is a closed system of water purification from suspended particles of mineral oil. Recommended for use on construction sites of the city who do not have time connection to utility networks and communications. There are various configuration items washes the wheels, including wheels for winter cleaning. Technical conditions for laying tiles and installation of the pit. When using the facility without welded trestles road plates are placed parallel to each other with a slope inward at an angle of 10 degrees to the horizontal. In the space between them is placed U-shaped channel or groove is concreted with a bias toward pit for drainage. General bias toward the pit 5-10 degrees. Pit dimensions 1.5 * 1.5 * 1.5 concreted.

Can be laid in a half-brick walls, filled the bottom layer is 10 cm Also, instead of concreting, it is possible to use a welded, airtight container (sheet 2,0-2,5 mm). Submersible pump is suspended in a pit so that the distance of the bottom pump was at the height of 15-20 cm from the bottom of the pit. As the silt pit needs to be cleaned. Otherwise, can not exclude the possibility of breakage of blades pump with stones, rinse with plates. CSB Group of Companies has all the necessary documentation to install wheel wash items with a closed cycle Aquador. The principle of operation of the plant working Water Installation of water recycling washing the wheels of trucks designed for water purification from large suspended particles of sand, clay, soil and other contaminants of this nature at this Purified water is returned for reuse.


Profiler-gruntosmesitel DS-178 is structurally executed semi-trailer to the tractor K-701 (K-701M). Attachment to the tractor frame by a special tractor units. Semi-pneumatic to go equipped fluid-brakes. The tractor has a creeper with a hydraulic drive enables you to change the operating speed continuously within 1.5-15 m / min. Transport speed of the car matches the transport speed tractor. Rotor, compactors, water pump – hydraulic.

The situation of workers supported by the automatic system Die sinking of one column. The direction of movement is supported by the tractor steering controlled by the control indicator on the remote control in the cab of the same cord Die sinking. equipment machinery: universal working body of the milling rotor blades and cutting teeth for profiling, and mixing the soil and the auger screw winding feathers water supply system in the mixing zone of soil, consisting of a water tank (capacity 4.5 cu. m), water pump, a set of nozzles across the width of the rotor; tamper with the mechanical vibrator vibration directions. Commissioned by the working body can be mounted disc thrower soil, through which excess soil removed during profiling beyond the earth canvas or loading in . subgrade to within 10 mm from the cord Die sinking with the removal of surplus soil on the right side of the curb along the machine, cutting trough to a depth of 200 mm in one or two pass (depending on the type of soil), soil mixing with granular or liquid binders directly on the roadway in one pass, pre-packing of ready mix compactors. Profiling and mixing soil with a binder made universal rotor and screw in two passes on one track.

Technological scheme of the machine with the working body can be shuttle or with a turn at the end of the aisle. The second scheme is preferable as feeding the machine in reverse to the starting position with two hinges (hinge frame of the tractor and the tractor unit) is less effective. When profiling the subgrade screw working Body falls Ram lowest position. The flap, which separates the mixing chamber by the auger, hydraulic cylinders up to the top position. Hydraulic compactors and water systems are turned off. Ground cut milling rotor mounted on the depth of auger blades thrown and the camera is thrown to the side of the screw. When mixing the soil auger mechanism rises to its highest position, throttle omitted, the drive plate compactors and water system go to work. Crushed and ground Mixing Capacity rotor with cement and water leveled the bottom edge of the damper, denser plate compactors, and then ukatyvaetsya pnevmokatkami.

Cable Jacks

Cable Jack – it's lifting mechanism for raising the cable reel on a small height, is used as a device who gives the winding and cabling. The basic principle of the cable jacks: a central hole threaded cable drum axle jack, axle set centering cone or sleeve, podzhimnye shoes moving along the axis of the drum to the cheeks and fixing clip. Racks Cable jack installed on both sides of the drum, providing a working gap between the cheek and a drum rack design (typically 100 mm.), a significant increase in this gap will increase the bending point on the axis, and thus the possibility of breakage. Next aligned with the axis of lodgements and will be involved lifting mechanism, whether it be a pair of helical, hydraulic or lever system. Lifting is carried to an altitude that provides compensation for uneven cheeks drum plus a guaranteed gap between the cheek and the surface, on which stand rack is usually about 50 – 100 mm cable jack main units: the rack, hoist, tool tray, axle. Cable jacks are classified: 1.Po operating principle: Screw the cable jacks – jacks is working on a pair of screw type (screw-nut) at the same time, usually in the process of lifting a cable drum nut rotational motion, and the screw forward. Screw the cable jacks in turn are divided into: push, cable jacks tyanuschie.Gidravlicheskie – it jacks, in which as the hoisting mechanism uses a hydraulic cylinder or hydraulic jack. The rise of the cable drum is accomplished by reciprocating the handle or hydraulic power station domkrata.Rychazhnye cable jacks – jacks is that the rise of the cable drum by means of a lever, the required force develops due to the difference shoulders arms and lodgement with respect to the support. 2.Po lodgement design: from mobile elements – a cable jacks, providing lightweight rotation axis installed on them, used when necessary to provide a low resistance when unwinding the cable, such as lack of lodgement include the inertia of the system, that is when the unwind reel having some speed, because of the large mass, has a decent inertia and as a consequence of long stops, after the removal of the applied efforts; c fixed point set axis. 3.Po design osikabelnye jacks with ball bearings, cable jacks without bearings. Accessory cable reels are Podzhimnye boots on the axle – to avoid move along the axis of the drum during the winding cable centering cone – for smooth and secure the cable unwinding, Wheel bearings – for maximum cable jacks provide the ability to unwind cable to the cable drums of different sizes.

Electromagnetic Locks: Locks Class Premium

Electric lock remotely open the door to transfer the electrical signal. Electric locks are used in conjunction with the intercom, code reader panels and cards in access control systems. There are two classes of electric locks: – electromagnetic locks, door is held by the action of an electromagnet built – electromechanical locks, door is held closed by a mechanical crossbar, which is controlled by a thin solenoid. Electromagnetic locks are used in access control systems. The component elements of the electromagnetic lock are: housing, built-in magnet, the response metal plate. The mechanism of the electromagnetic lock.

Electromagnetic locks keep the doors in the closed position by the action of a strong magnet, attracting to itself the metal plate, mounted on the door. To open the door use exit button or a control signal received from the controller, control systems and access control. Electromagnetic locks are very simple and easy to use, besides have a long service life. One significant negative of these locks, they work, provided uninterrupted power supply. Therefore, for normal system operation must be applied backup power units. Among manufacturers of electromagnetic locks can be distinguished Russian company Rocks Entrance. Ltd. 'Rocks Entrance' was created in 2001 as the successor of a famous company 'ALEKO', which specializes in the design and manufacture electromagnetic locks for security.

Production of the first castles 'ALEKO' was organized in 1994 and has since steadily expanded their range. Currently, the company produces a series of electromagnetic locks ALer: – Shear electromagnetic locks – overhead electromagnetic locks – waterproof electromagnetic locks – osobouzkie electromagnetic locks – holding electromagnetic locks – power and control systems electromagnetic locks ALer; – electromagnetic locks for glass doors – overhead electromagnetic locks class PRemium. Electromagnetic locks Class PRemium are the winner of the competition program "Best innovation in security technology in 2008 ' Class PRemium includes four models with electromagnetic locks holding force of anchors 150kGs up to 400 kgs, a distinctive feature of which is: – an active status sensor Lock relay output – the existence of passive reed sensor door position – the existence of built-in light indicating the status of the castle. Built-in sensor states of the electromagnetic lock is based on the Hall sensor. At the moment of contact with the working surface anchor lock appears the magnetic field, which is when the set value will trigger the sensor, the signal from which closes the output relay contacts. State electromagnetic lock can be monitored visually using the built-in indicator. Red signal indicates the presence of the required level of magnetic field, sufficient to block the door. Green – the castle unlocked or the level of magnetic field are not adequately lock the door. Locks are available with voltage 12 or 24 volts. The use of electromagnetic locks Class PRemium allows full control access to the premises, as it defines all possible states of the door and lock.
