Today's utility contractors face critical challenges: finding and training skilled operators, minimising downtime and maintaining profitability in competitive urban markets. Vermeer states that its new D24 horizontal directional drill (HDD) helps address these fundamental needs while delivering the power and precision required for urban utility installation. Building on the robust foundation of its predecessor, the D23x30 S3, the D24 introduces automation and smart diagnostics that enhance operator capabilities and boost jobsite productivity.

The D24 is the result of extensive research, development and customer input

The D24 features a unique blend of advanced features tailored to tackle today's drilling challenges. Its innovative automated rod exchange (ARE) system streamlines drilling for operators across the skill spectrum while reducing wear on key components. Improved onboard diagnostics offer real-time troubleshooting, helping minimise downtime. These enhancements, along with top-tier hydraulic components, are said to establish the D24 as a significant advancement in utility installation technology.

Clint Recker, product manager for utility HDD equipment at Vermeer, explained the driving force behind the D24's development: "We've listened closely to utility contractors and incorporated their feedback into this machine. The result is a drill that sets new standards for ease of operation and maintenance simplicity. The D24 represents a significant step forward in HDD technology."

The powerful 24,000lb (110kN) class horizontal directional drill replaces the D23x30 S3 in the Vermeer utility drill lineup and boasts a 100hp (74.6kW) Cat 3.6L Tier 4F/Stage V engine.

The D24 delivers impressive performance with a max peak thrust and pullback of 24,700lb (110kN) and a continuous thrust and pullback of 22,000lb (98kN). It also features 3080ft-lb (4176Nm) of rotational torque and a 45gpm (170L/min) mud pump.

Packed with advanced features and technology, the Vermeer D24 HDD enables crews to efficiently install utilities — including fibre, power cables and water infrastructure in congested urban areas.

Automated rod exchange for increased efficiency

A standout feature of the Vermeer D24 HDD is its automated rod exchange (ARE) system. This innovative technology increases onboarding velocity for new operators, reduces the workload for skilled operators and maximises wear part component life through highly controlled processes. With a single button push completing the entire rod changeout sequence, ARE eliminates up to 19 manual steps, streamlining operations and enhancing overall efficiency.

With ARE, each rod change helps reduce wear on components and minimises the risk of human error. This can potentially extend the life of consumables like sub-savers and drill rods.

"ARE is a unique feature of the D24," Recker noted. "By automating the rod exchange process, we're helping contractors adapt to today's labour market while maintaining consistent, reliable operation." 

Enhanced diagnostics for improved productivity

The D24 features an advanced onboard diagnostic system, accessible via the machine's touchscreen display. This system offers operators and technicians comprehensive information about any issues and step-by-step troubleshooting guidance. It enables quick troubleshooting of issues, maximising operational time.

For example, if a sensor detects a hydraulic system anomaly, the diagnostic display provides detailed information to minimise diagnostic time. If dealer support is needed, the system equips technicians with comprehensive data, helping them arrive better prepared. This approach helps keep projects on schedule by getting the machine back to drilling sooner.

Recker emphasised the importance of this feature: "We're helping operators better understand what's happening with their machine. When an issue arises, the system guides them through specific checks they can make, look at this, check that, try this." 

Reliability and extended coverage

Vermeer has prioritised enhancing the D24's overall reliability. The machine features premium hydraulic components, typically found in larger pipeline equipment, that help protect the hydraulic circuit and extend its lifespan. These high-quality components improve the machine's durability and allow consistent performance across various drilling conditions.

Designed for urban work

The D24 is engineered to tackle the unique challenges of urban utility installation. Its compact design allows for efficient operation in confined city spaces while delivering the power and precision needed to handle diverse soil conditions. This balance of size and capability makes the D24 an ideal choice for contractors working in densely populated areas.

The D24 operates at just 88dB(A) at the operator's ear with a guaranteed sound power level of 100dB(A). This low noise output minimises disturbance in sensitive urban areas, enhances onsite communication, and helps contractors meet certain local noise regulations. The D24's operational sound levels contribute to a comfortable work environment, which can positively impact crew productivity and job satisfaction.

Features for efficient operation

Operators can choose between 400ft or 480ft (122m or 146m) of 2.375in Firestick drill rod for the D24, selecting the configuration that best suits their typical job requirements.

The redesigned vice system features sliding open-side vices, enabling easy cleaning and clear joint visibility. This sliding mechanism streamlines the breakout process compared to fixed open-top vices. With enhanced clamp force, the vices help extend the life of the vice die.

The D24's stakedowns feature tiered shark teeth and a rotation speed of up to 60rpm, nearly triple that of its predecessors. This upgrade improves setup efficiency, especially in harder soils, allowing crews to begin drilling faster. This quicker setup is particularly valuable in urban areas, where minimising disruption is crucial.

Contributing to its efficiency on the jobsite, the D24 boasts impressive speed capabilities. With a rotation speed of 198rpm and a carriage speed of 181fpm (55m/min), crews can install more feet of product per day. The drill's 3.3mph (5.3km/hr) tracking speed enables quick relocation between work areas, helping further enhance productivity.

"The D24 is the result of extensive research, development and customer input," Recker explained. "We're confident that contractors will see an impact in their operations when they use this machine in the field. It truly sets a new standard for HDD equipment. We believe contractors will be impressed when they put this machine to work in the field, as it truly raises the bar for what they can expect from their HDD equipment."

The Vermeer D24 HDD represents a significant step forward in horizontal directional drilling technology. By combining automated features, advanced diagnostics and proven performance in a compact package, Vermeer has created a machine that addresses the evolving needs of utility contractors working in challenging urban environments.

Recker concluded: "The D24 is designed to boost productivity on the jobsite. We believe contractors will experience streamlined operations and fast project completion times with this innovative HDD equipment."

Vermeer has introduced a simplified model numbering system for its new drills. This system represents each unit's respective drill class, making it easier for customers to understand the machine's capabilities. The D24 replaces the D23x30 S3 HDD in the Vermeer utility drill line, with its name signifying its thrust capabilities.
