DCP1005H Low Clearance Full Casing Rotary Drilling Rig

Short Description:

The SEMW DCP1005H Low Clearance Full Casing Rotary Drilling Rig is designed for foundation construction in tunnels, bridge culverts and other restricted-access environments. It supports Ø500–1000 mm drilling diameters, with three rotary torque settings of 845 / 525 / 290 kN·m.

Featuring crawler-mounted equipment units and an electric hydraulic power station, the DCP1005H supports casing installation and extraction where conventional tall drilling equipment may be difficult to deploy. SEMW specifies a maximum pile depth of 40 m, subject to suitable ground conditions and construction arrangements.

Product Overview

The SEMW DCP1005H Low Clearance Full Casing Rotary Drilling Rig is developed for pile foundation work in confined spaces, including tunnels, bridge culverts and restricted-access construction areas. Its Ø500–1000 mm drilling range is paired with a compact crawler-mounted working unit and a separate electric hydraulic power station.

Unlike conventional tall casing rotators, the DCP1005H emphasizes equipment access, repositioning and drilling within limited headroom. SEMW describes applications in working spaces around 4 m wide and 4.8 m high, with a stated maximum pile depth of 40 m; feasibility still depends on the complete site arrangement and approved construction plan.

01 / LOW HEADROOM

Built for Restricted Access

Designed for tunnels, culverts and sites where equipment height and available working width limit conventional piling machinery.

02 / CASING DRIVE

Three Torque-Speed Settings

Delivers 845 / 525 / 290 kN·m rotary torque with corresponding speeds of 1.25 / 2.3 / 4.15 rpm for different operating conditions.

03 / SITE MOBILITY

Crawler-Mounted System

Working unit and power station use crawler travelling systems to assist positioning and movement around suitable site surfaces.

Low-Clearance Construction & Site Planning

Space limitations determine how low-clearance drilling is planned. The DCP1005H uses a hydraulic casing rotator working unit and a separately powered station, connected during operation to support casing rotation and vertical movement. Excavation and casing handling must be coordinated with suitable auxiliary equipment.

01. Check the available envelopeConfirm tunnel or culvert width, clear height, entrances, equipment transportation route and any overhead restrictions.
02. Verify foundation requirementsMatch pile diameter and target depth to the DCP1005H specifications, geology and project method statement.
03. Arrange equipment and powerPlan crawler travel routes, lifting or excavation equipment, the electric power supply and hydraulic hose connections.
04. Execute casing-supported drillingPosition the machine, rotate and advance casing, excavate inside it and complete pile operations in the approved sequence.
The stated 40 m pile depth and example space of 4 m width × 4.8 m height come from the SEMW website. These are not substitutes for site-specific checks of clearances, auxiliary equipment and ground conditions.

Applications & Equipment Selection

Typical evaluation scenarios: tunnel pile foundations, bridge culvert works, low-headroom foundation construction and restricted-access infrastructure sites requiring Ø500–1000 mm fully cased drilling.

When selecting the DCP1005H, contractors should supply the available headroom and width, pile layout, required depth, ground investigation, casing details, site access and electrical power conditions. Unlike the larger conventional CRD models, the primary selection consideration here is whether the complete drilling operation can be performed within the available space.

For related standard casing rotator models, see the SEMW Casing Rotator Series. Choose according to the required diameter, working clearance and construction method rather than model size alone.

Frequently Asked Questions

Q1. What drilling diameter can the DCP1005H handle?

The SEMW brochure specifies a drilling diameter range of Ø500–1000 mm.

Q2. Why is the DCP1005H intended for low-clearance sites?

Its crawler-mounted working unit and separated electric power station are designed for foundation drilling where available height and access restrict larger equipment. The complete working arrangement must be checked for each project.

Q3. What is the casing pull-out force?

The rated casing pull-out force shown in the brochure is 2411 kN, with an instantaneous peak of 2733 kN.

Q4. Does the hydraulic power pack use a diesel engine?

The DCP1005H brochure specifies an electric motor power pack with total installed motor power of 207.5 kW (110 + 90 + 7.5 kW).

Q5. What information should be provided for technical selection?

Provide working width and height, pile diameter and depth, geological information, casing requirements, the available electrical supply and any access or lifting limitations.
