High-torque equipment and tools designed to optimize pile construction across Berlin and European civil projects.
Berlin's subsurface geology presents a unique set of challenges for structural engineers and piling contractors. The city is situated on the Berlin-Warsaw glacial valley (Urstromtal), characterized by high concentrations of fine-to-medium sand, organic peat lenses, and a exceptionally high groundwater table (often situated just 2 to 4 meters below the surface). Excavating deep foundation shafts for commercial developments, municipal projects, and transit extensions like the U-Bahn requires precise, high-torque drilling equipment capable of handling continuous stress while maintaining borehole stability.
In these geological conditions, cased rotary drilling utilizing advanced Kelly Bars is the industry-standard method. The Kelly bar serves as the mechanical transmission component, transfering torque from the rotary drive of the drilling rig to the boring tool (auger or drilling bucket). Because Berlin’s sandy soils are highly susceptible to collapse when saturated, drilling operators must use heavy temporary casings or polymer bentonite slurries. This necessitates high-strength interlocking Kelly bars that can apply high crowd forces (downward pressure) to drive the casings through alternating dense sand and glacial till layers.
Berlin's close proximity to the Spree and Havel river basins means drilling runs must prevent soil liquefaction and water-driven collapse inside the borehole.
Telescopic Kelly bars must align perfectly with casing oscillators to push large-diameter steel tubes through tough gravel deposits.
Friction Kelly bars offer high speed in soft soils, whereas Interlocking versions ensure maximum torque transfer in hard, compacted sand and clay layers.
Deep foundation technology has transitioned from heavy, mechanical-only systems to integrated cyber-physical machinery. Globally, infrastructure demands in urban environments require noise-reduced, vibration-dampened piling solutions. In Germany, strict environmental guidelines dictate low emission levels and minimal ground disruption, accelerating the adoption of cased continuous flight auger (CFA) methods and rotary drilling with advanced electronic controls.
As a prominent global supplier, SINOVO Heavy Industry has spent more than 20 years developing pile engineering machinery that aligns with European safety regulations and mechanical standards. Our integration of high-tensile alloy steel (such as 35CrMo or 42CrMo), state-of-the-art heat treatment procedures, and optimized keyway profiles ensures that SINOVO Kelly bars maintain structural integrity under continuous peak torque conditions, reducing downtime on critical Berlin project sites.

The business scope of SINOVO group is mainly focused on pile construction machinery, hoisting, water well drilling and geological exploration equipment, sales and export of construction machinery and equipment, as well as the solution of machines and tools. It has established trade relations with more than 120 countries and regions in the world, forming a sales, service network and diversified marketing pattern on five continents.
All products have successively obtained ISO9001:2015 certification, CE certification, and GOST certification. Among them, the sales of piling machinery is the first brand in China in Southeast Asia market, and has continuously become the excellent Chinese supplier of African exploration industry. And in Singapore, Dubai, Algiers design services, to provide global technology and spare parts supply quality after-sales service.
In 2008, the company carried out strategic integration and established TEG FAR EAST company in Singapore to strengthen the development of Southeast Asian market.
In 2010, the company invested in the production and manufacturing base of Hebei Xianghe emerging industry demonstration zone, covering an area of 67 mu, with a total investment of 120 million yuan, engaged in the R & D and manufacturing of pile engineering machinery, hoisting, water well drilling and geological exploration equipment. The factory is located in Xianghe Industrial Park, 100 km away from Tianjin port, reducing transportation costs.
Beijing Sinovo International & Sinovo Heavy Industry Co. Ltd. are ISO9001: 2015 certified manufacturer of drilling rigs and piling rigs. Since our beginning, we have been committed to providing high quality drilling equipment to global customers. Thanks to our efforts over the years, we have established a production base that occupies an area of 7,800 square meters and is equipped with over 50 pieces of equipment. In order to satisfy increasing market demands, we continually work to increase our production capacity.
In addition, thanks to the hard work of our professional engineers, we are at the forefront of the field of electronic hydraulic control and drive systems, which helps keep our drilling equipment competitive in the market. Our company is located in Beijing City, the capital of China. Here we have access to convenient transportation, abundant labor resources, and advanced technology. This facilitates the production and shipping of our products and allows us to provide them at lower prices.
A high-quality Kelly bar must exhibit a fine balance between elasticity (to absorb torsional impacts) and hardness (to prevent deformation of driving ribs). The transfer of rotational torque from the rotary drive table to the telescope requires a precise locking system. SINOVO provides two primary technical classifications for the Berlin market:
Designed with specialized locking pockets along the drive keys. When crowd pressure is applied, the drive keys lock into these pockets, allowing the rig to transfer high downward force directly to the boring tool. Highly recommended for drilling through hard clay deposits, compacted gravels, and structural obstacles in urban Berlin.
Utilize continuous friction ribs along the outer surface of each telescopic section to transmit torque. They do not have mechanical lock points, enabling faster raising and lowering cycles. Best suited for soft sandy layers, silt deposits, and water-logged ground conditions where slurry or casing is already in place.
Metallurgical Superiority: The tube steel used in SINOVO Kelly bars is sourced from major global steel suppliers. Our engineers utilize advanced thermal processes to harden the key guides, extending the wear lifespan by up to 45% compared to standard steel grades. The spring box assembly at the base of the bar absorbs structural shocks during drilling, shielding both the rig's rotary drive and the telescopic components from structural fatigue.
Ensuring operational continuity with a comprehensive service framework and technical assistance.
As a long-established drilling rig manufacturer in China, SINOVO group do business with reputation and word of mouth. We are dedicated to provide customers perfect service.

Answers to common technical queries about drilling rigs, Kelly bars, and Berlin subsurface conditions.
Due to the risk of collapse in water-bearing sands, friction Kelly bars are often used alongside slurry stabilization systems. However, if temporary casing must be driven through denser glacial till layers, an interlocking Kelly bar is necessary to provide the required downward crowd force.
We manufacture our bars using high-strength alloy steel tubes, such as 35CrMo and 42CrMo. These steels undergo specialized heat treatments to withstand high torque loads and resist structural deformation.
Yes, our entire export range is ISO9001:2015, CE, and GOST certified, ensuring full compliance with European construction safety and performance standards.
