Product Overview
The SEMW CRD2106H Casing Rotator is a fully hydraulic casing rotation machine for Ø1000–2100 mm fully cased foundation drilling. It combines casing rotation with hydraulic downward and pull-out forces, supporting casing installation and extraction as part of a coordinated excavation process.
With a maximum operating rotary torque of 3,085 kN·m, an instantaneous peak torque of 3,505 kN·m and a 500 mm pressure-pulling stroke, the CRD2106H has its own performance configuration. Project engineers should evaluate the diameter, casing resistance, geology and lifting requirements before selecting the equipment.
Ø1000–2100 mm Range
Designed for the stated full-casing drilling diameter range, including applications requiring bores up to 2,100 mm.
Three Torque-Speed Settings
3,085 / 1,823 / 1,030 kN·m at corresponding speeds of 0.9 / 1.5 / 2.7 rpm.
Hydraulic Casing Control
3,760 kN pull-out force, an instantaneous peak of 4,300 kN and a 600 kN maximum downward force.
Technical Specifications
CRD2106H model-specific data from the supplied SEMW technical drawings. Peak values are instantaneous ratings, not continuous operating specifications.

Construction Approach
For full-casing construction, the casing rotator applies rotary torque and vertical force to steel casing, while suitable excavation tools remove material within the casing. The casing provides bore support as work progresses. Specific tooling and sequences depend on geological conditions and the approved construction method.
Applications
Bridge & Transportation Foundations
Evaluate the model for large-diameter, fully cased pile work where drilling diameter and site requirements match its specifications.
Urban Deep Foundations
Consider casing-supported excavation in constrained urban projects, subject to ground and site assessments.
Challenging Subsurface Conditions
Assess casing resistance, mixed ground and potential obstructions along with excavation-tool suitability.
Casing Installation & Extraction
Review the required casing dimensions, lifting arrangements and pulling-force demands.
Frequently Asked Questions
Q1. What is the CRD2106H drilling diameter range?
The published range is Ø1000–2100 mm. Project-specific casing selection also depends on depth, geology and construction requirements.
Q2. What torque and speed settings does the machine provide?
Three paired operating settings are listed: 3085 kN·m at 0.9 rpm, 1823 kN·m at 1.5 rpm and 1030 kN·m at 2.7 rpm. The instantaneous peak torque is 3505 kN·m.
Q3. How does CRD2106H differ from CRD2005H?
CRD2106H covers diameters up to 2100 mm and has a 500 mm pressure-pulling stroke, while CRD2005H covers up to 2000 mm and has a 750 mm stroke. They also have different torque-speed configurations and machine weights. The best choice requires site-specific assessment.
Q4. What information should be provided before equipment selection?
Provide the required pile diameter and depth, geological report, casing specifications, ground resistance expectations, working space and available excavation and lifting equipment.
