In rotary drilling and heavy piling operations, the main winch acts as the critical mechanism governing drilling depth, feed control, and load safety. An optimized main winch system must operate reliably under immense tension, harsh environmental fluctuations, and frequent lifting cycles. As a pioneering force in foundation engineering solutions, SINOVO Group manufactures drilling rigs equipped with state-of-the-art hydraulic winches. Our systems feature advanced hydraulic loading back technology, electronic hydraulic control drives, and load-sensing systems designed to optimize speed and torque match-up dynamically.
For European and global markets, CE Certification is not merely a label; it represents rigorous adherence to structural integrity, functional safety, and risk prevention protocols under the Machinery Directive 2006/42/EC and EN 16228 standards. SINOVO's commitment to these safety standards ensures that each main winch unit undergoes strict overload testing, multi-disc fail-safe brake evaluation, and Lebus groove drum alignment to completely eliminate wire rope overlap and premature wear.
Analyzing the technical safety frameworks that govern the design, safety features, and reliability metrics of our winching systems.
Equipped with integrated electronic pressure transducers, our hydraulic circuits limit rope tension dynamically. This prevents structural overloads on the mast and Kelly bar during heavy extraction operations in adhesive soil formations.
Our main winches are designed with spring-applied, hydraulically released multi-disc brakes working in conjunction with a dynamic counterbalance valve control, ensuring stable holding capacity even during complete hydraulic power losses.
By engineering custom-grooved winch drums, SINOVO guarantees symmetrical wire rope winding across multi-layer spools. This layout minimizes mechanical wear, eliminates wire pinching, and matches EN 16228 requirements.
In contemporary civil engineering, infrastructure scales are demanding deeper foundations and wider shaft diameters. This structural demand shifts immense pressure onto the rotary rig's main winch system. A reliable winch directly corresponds to faster cycle times when lifting deep drilling rods (such as friction or interlocking Kelly bars). Under modern site conditions in metropolitan European or North American areas, noise level limits, low emission zones, and mechanical fail-safes are strictly monitored.
SINOVO Heavy Industry tackles these global commercial and industrial realities by integrating variable displacement hydraulic motors (typically sourced from Rexroth or Kawasaki) which modulate torque based on live load demands. This dynamic management reduces overall thermal generation within the hydraulic oil reservoir, lowers fuel consumption of the rig chassis engine, and ensures a long structural lifespan for the internal gearing systems.
From the early 1990s to our modern 67-mu integrated industrial zone, tracing SINOVO's path of engineering excellence.
As early as the early 1990s, the backbone members of SINOVO Group have been serving in the field of construction machinery. Over more than 20 years of continuous iteration and development, the company has established long-term strategic alliances with world-class component suppliers and major regional distributors, earning continuous accolades in the export arena.
In 2008, we consolidated our international outreach by establishing the TEG FAR EAST corporation in Singapore, targeting deep foundation projects across Southeast Asian markets. Following this, in 2010, SINOVO invested over 120 million Yuan to construct a manufacturing base in the Hebei Xianghe Emerging Industry Zone. Spanning 67 mu (approximately 44,600 sqm), this facility is strategically located 100 km from Tianjin Port, giving us excellent logistical advantages for exporting large-scale equipment worldwide.
Today, our Beijing Head Office (Beijing Sinovo International & Sinovo Heavy Industry Co. Ltd.) operates under a certified ISO9001:2015 Quality Management System, overseeing an annual manufacturing volume of 1,000 core drilling rigs, 250 water well drilling units, and 120 heavy rotary drilling rigs.
