An achievement worthy of "BMW" pride
Fourth generation single drum roller
Compaction characteristics
Static linear load
The higher static linear load increases the compressive strength and increases the thickness of the compacted fill layer.
frequency
The frequency is high, resulting in more impacts per second. It can increase the driving speed and has a higher production area of ​​compacted area (especially surface finishing compaction).
amplitude
The standard setting for all machines is dual-band and double-frame. Dual amplitude machines provide optimum depth effects (high amplitude/low frequency) and surface compaction (small amplitude/high frequency).
2. Steel wheel design
Excitation unit
The two exciter assemblies, together with the eccentric weights, are housed in a completely sealed enclosure.
The exciter eccentric weight operates in a tank filled with silicone oil.
The eccentric weight of BOMAG ensures control and quiet adjustment (filling silicone oil).
Advantages: less wear and long life. The exciter is mounted on a proven double vibration generator structure.
Shock absorber
The damping rubber separates the vibration of the vibrating wheel from the rest of the machine.
The damping rubber can be exchanged separately. It can be removed without special tools on site.
Advantages: low cost.
3. Rack / articulated / tire
Front rack
The newly designed upturned front frame is fully bolted and has a large opening in the steel plates on both sides.
Advantages: Good accessibility for cleaning and maintenance.
Scraper
Standard elastic steel scraper with a large adjustment range.
In order to achieve higher scraping requirements (eg cohesive soil), steel or rubber, contact scrapers can be used.
Advantages: The rollers can be kept clean depending on the application. The soil surface remains flat and tight.
Component protection
All bolts in the front frame sink below the surface. No parts are protruding beyond the surface
The hydraulic tubes are properly guided and protected against possible damage.
Advantages: Real-time pressure on the wall or other equipment, no risk of damage.
Articulated joint
The articulated head is equipped with a powerful ball bearing to ensure the transmission of large forces.
Advantages: maximum service life
The joint has a large steering angle (35°) and a swing angle (12°)
Advantages: The single-wheel roller has excellent steering performance even in difficult areas.
The joints are all bolted to the front/rear frame.

Rear frame
The rear frame is almost enclosed.
Advantages: The engine, assembly, and piping are protected from damage and pollution!
4. Driving System - Engine
Driving system
The single drum roller has a powerful hydrostatic drive system; the torque of the hydraulic motor can be adjusted according to the individual needs (driving or working on a horizontal or slope).
When a tire is not in contact with the ground, the non-slip shaft can also transfer all the torque to the ground.
Compaction wheel drive
The running bearings of the whole machine are sealed by a highly efficient sliding seal. The running bearings are completely maintenance-free!
Advantages: Not sensitive to the strict fine materials of dust and Egypt.
engine
The single drum roller has a high-power diesel engine with low emissions and low fuel consumption.
Advantages: Strong work and low fuel costs. There is no need to refuel throughout the working day.
DH series engine with ECOMODE system, the engine speed is automatically adjusted according to the load, and the actual fuel economy is saved by more than 30%!
The engine comes standard with a fuel primary filter with a water separator.
Advantages: Added additional protection for engine contamination.
Air inlet
The air for combustion and cooling enters from the top.
Advantages: Less dust particles enter the filter, prolong the life of the filter element, and low operating costs.
The exhaust gas is discharged upwards at the front of the roller.
Pros: Don't raise extra dust!
exhaust
The engine exhaust is located outside the engine. This reduces the thermal load on all components.
Advantages: Low heat load extends service life.
Exhaust emissions are discharged from the rear to the air.
Advantages: no extra dust is raised. The driver will not be exposed to the exhaust gas!
5. Electrical system
Centralized electrical system
All newly designed BOMAG single drum rollers are equipped with a modular design of the centralized electrical system. These modules are identical on all machines and can be replaced on different machines.
Advantages: The smallest inventory of accessories!
There are no large relay sections. All functions are separated and can be easily replaced when needed and at a low price. All cables, fuses, and relays are clearly arranged, marked with line numbers, and directed to a centralized position.
Advantages: Quickly analyze fault locations.
A large number of optional wiring terminals are pre-set
Advantages: Quick and easy assembly of options in the customer's repair shop.
6. Operating system - safe and comfortable
operating
The sensitive operating handle allows the machine to shift gears smoothly. The roller has four driving gears, and the traveling motor is adjusted to go uphill and downhill. An emergency stop can stop all functions and automatically brake.
Advantages: It can be easily operated for drivers with little experience.
Safety
1 x 1 meter of field of view - an object one meter high in front of the machine can be observed. It is important to see objects 1 meter high and 1 meter high behind the machine.
Standard sound reversing alarm.
Advantages: The highest security for both people and machines!
noise
The BOMAG single drum roller is the quietest machine on the market.
7. Cab
1The driver's cab is equipped with the following items as standard:
* Overall ROPS
* 2 sets of work lights (front + rear)
* Wiper with wind window cleaning system on both front and back
* Seat belt
* 2 large external inverted mirrors
* Large storage box (left)
* 2 large windows that can be opened
* Ceiling exit
* All fuses required for the driver's indoor function are centrally installed on the cab roof; easy to access.
Advantages: The cab provides safety and is immune to the weather.
Noise in the driver's cab
The BOMAG single drum roller is the quietest roller on the market. No vibration is 70 dB(A), and vibration is 78 dB(A)
Comfortable cab seat
Vertical adjustment
Height adjustable (80mm)
Adjust according to driver weight
Adjustable angle of the back of the driver's seat
Foldable driver's seat armrests on the left and right sides

This novel VT type Electric Wire Rope Hoist is made with 13 patented technologies.
As contrasted with conventional designs, the VT type electric wire rope hoist is a revolutionary new generation product. It houses many brilliant brilliant attributes, such as a superb performance, short headroom, accurate positioning, great operating comfort, and maximum security and reliability, all encompassed in a compact design. It is a multi-functioning machine that has revolutionized the way the wire rope hoist is designed and manufactured.
With a hoisting capacity ranging from 800kg to 250,000kg,the lift can take the load up to a maximum height of 103.6m.Plenty of models, Configurations and specifications exist for the hoist, from which customers are sure to find the perfect match.
Advantages
Short headroom allows large vertical operating space for the wire rope hoist. Size-C hoist design leaves more vertical space for lifting. Such attribute can be hardly found in any of its contemporaries. The hoisting hook can reach much closer to the side walls. Minimum side clearance effectively enlarges the work area.
Dynadrive is designed for stable running and fast positioning. It can minimize the load sway and improve operating safety and comfort. Each component of our electric wire rope hoist is rigorously inspected and tested by our qualified engineers to ensure the safety and working efficiency the final product.
