ZT-32 KF
The Drillto ZT-32KF is a 32-ton-class Horizontal Directional Drilling (HDD) machine designed for trenchless underground construction. It uses controlled horizontal drilling to install pipelines, conduits and utility lines with minimal surface excavation. Drillto describes the machine as using advanced and proprietary technologies, with key components from imported or joint-venture suppliers.
The ZT-32KF is designed for medium-duty trenchless utility installation, particularly where conventional open-cut excavation would cause significant disruption. Its 320 kN maximum pulling and thrusting force and 12,000 N·m maximum torque provide the capability to bore and pull underground utility pipelines through various construction environments.
Its relatively compact dimensions and 8–20° entry-angle range make it suitable for projects where working space is limited.
Applications
The ZT-32KF can be used for trenchless installation of:
- Water supply pipelines
- Sewer and drainage pipelines
- Gas pipelines
- Electrical power conduits
- Telecommunication and fiber-optic ducts
- Utility infrastructure crossings
- Road and highway crossings
- River or drainage crossings
- Urban underground utility projects
- Pipeline replacement or rehabilitation projects
1. Semi-automatic arm swing
The semi-automatic arm-swing system helps improve drilling efficiency and reduce manual labor requirements.
2. Low entry angle
The 8–20° entry angle allows the rig to start drilling relatively close to ground level, helping conserve working space and drill rods.
3. Strong pulling and thrusting capability
With 320 kN maximum pullback force and 320 kN maximum thrust force, the machine can handle demanding drilling and pipe-installation operations.
4. High rotary torque
The 12,000 N·m maximum torque provides substantial rotational force for drilling and reaming.
5. PERMCO triple main pump
The machine uses a PERMCO triple pump hydraulic system, which Drillto specifies for stable operation.
6. Italian SANT two-speed valve
The two-speed valve provides controlled hydraulic operation and is specified by Drillto as an Italian SANT component.
7. Rear-leg hydraulic support
A large-cylinder angled rear support provides stability during drilling operations.
8. Operator comfort
The machine is equipped with a rain canopy, fan and lighting to provide a more practical working environment during construction.

*There is a specification discrepancy across published sources: Drillto’s current product page lists 132 kW, while Siccion Marketing’s ZT-32KF page lists 153 kW @ 2,200 rpm. The current Drillto page should be treated as the manufacturer’s primary reference, but the engine rating should be confirmed with Drillto for a quotation or technical proposal.
