Product Overview

CRD1605H Casing Rotator

The SEMW CRD1605H is a fully hydraulic casing rotator for Ø800–1600 mm foundation drilling. Compared with the CRD1305H, it covers a larger drilling diameter range and provides a different rotary torque-speed configuration for fully cased pile construction.

Its hydraulic system rotates and advances steel casing while supporting controlled extraction. Equipment suitability depends on pile dimensions, ground conditions and the required casing forces.

Construction Method

Matching Rotary Torque and Speed to Casing Resistance

The CRD1605H rotates and presses steel casing into the ground while suitable excavation tools remove material from inside. Its three torque-speed settings allow the operating mode to be evaluated against casing resistance, geological conditions and the planned excavation method.

Position Equipment

Align the casing rotator and prepare supporting equipment.

Advance Casing

Rotate and press the casing under the selected operating setting.

Excavate Inside

Remove soil and obstructions using suitable tools as casing advances.

Complete the Pile

Finish pile construction and casing extraction according to the approved method.

Applications & Selection

The CRD1605H can be evaluated for fully cased drilling in bridge foundations, transportation infrastructure and urban foundation projects that require a drilling diameter of Ø800–1600 mm.

Bridge Foundations — pile construction with casing support

Urban Foundation Works — controlled excavation near existing infrastructure

Mixed Ground Conditions — projects requiring careful casing and tool selection

Underground Obstructions — selected removal tasks with suitable auxiliary tools

CRD1605H or CRD1305H?

CRD1605H offers a larger drilling diameter range (Ø800–1600 mm versus Ø600–1300 mm) and higher maximum operating rotary torque (1,525 versus 1,400 kN·m). Both models list a casing pull-out force of 2,440 kN. Final selection must consider depth, geology, casing friction and supporting equipment.

FAQ

Q1. What drilling diameters does the CRD1605H support?

The published drilling diameter range is Ø800–1600 mm.

Q2. How do the CRD1605H torque-speed settings differ?

The three corresponding settings are 1,525 kN·m at 1.3 rpm, 906 kN·m at 2.2 rpm and 512 kN·m at 3.9 rpm.

Q3. Does the CRD1605H have a higher casing pull-out force than the CRD1305H?

No. Both models list a casing pull-out force of 2,440 kN. They differ in drilling diameter range, torque, speed, downward force and base-machine weight.

Q4. When should contractors consider the CRD1605H?

Consider this model when the required drilling diameter lies within Ø800–1600 mm and its torque-speed settings suit the ground and casing resistance. Final suitability requires a technical review.
