Recently, Tyhen Foundation KR240E rotary drilling rig was used in a housing construction project in Quanzhou City, Fujian Province. The geological conditions  are mainly silt sand and silty clay layers, high-level groundwater, pile diameter 1000mm, and the single hole depth 35m. Based on the condition, Tyhen's team promptly prepared the appropriate mud ratio for mud wall protection, and cooperated with the operator's reasonable Kelly bar lifting speed control to solve the problem of hole collapse during construction in quicksand strata. In the end, the single hole formation time was shortened to In 1 hour and 45 minutes.The construction task was completed smoothly and efficiently within 20 days, reducing construction costs for customers and winning unanimous praise from customers.

KR240E high-performance fully hydraulic rotary drilling rig

Features:

● Selected powerful original American Cummins engines, combined with the electronic control system and hydraulic system of Tysim’s core technology, to give full play to its working capabilities;

● The whole series of products have passed the national standard GB certification and the EU EN16228 standard certification, better dynamic and static stability design to ensure construction safety:

● Tysim’s self-made special chassis for rotary drilling rigs perfectly matches the power system and the hydraulic system, and adopts the most advanced load sensing, load-sensitive and proportional control hydraulic systems in the country to make the hydraulic system more efficient and energy-saving;

●The classic model with stable performance and reliable quality;

●The power head set up the rock entry mode, reducing the operator's operating strength, and the rock entry ability is stronger;

●Multi-stage shock absorption design of the power head, the shock absorption effect is more excellent;

●The front large drum, the wire rope is only wound in two layers, maximizing the use of wire rope;

●Powerful slewing braking performance, ensuring construction stability and safety in extreme drilling conditions, and ensuring the pile verticality :

●Using a new generation of ergonomically designed ROPS cab, the operation is more comfortable and safer.
