HT20 Pro Mini Excavator： Retractable Track & Enlarged Boom

HT20 Pro Mini Excavator: Retractable Track and Enlarged Boom for Confined Sites

The HT20 Pro is a 1470kg crawler mini excavator built for contractors and rental companies that need a machine capable of working in varying site conditions. Its defining feature is a retractable undercarriage: the track width adjusts from 970mm to 1270mm. Narrow setting allows the machine to pass through gates and alleys; wide setting provides a stable working platform for digging. This single design element addresses a common problem for equipment buyers—one machine that can both access tight spaces and perform stable excavation work.

Enlarged Inverted Boom

The HT20 Pro uses an enlarged inverted boom design. The boom cylinder is inverted, and the structural dimensions are enlarged compared to standard models. This configuration provides a larger lateral digging range, which is useful when working along edges, foundations, or walls. The maximum digging depth is 1995mm and the maximum digging reach is 3130mm.

Concealed Plunger Travel Motor

The machine is equipped with a concealed plunger travel motor. This component is positioned within the undercarriage structure, protecting it from external impact and debris on the job site. According to the manufacturer’s specification, the design is intended for stable performance under continuous high-load conditions.

Dual-Speed Travel System

The HT20 Pro has two travel speed settings. Low speed provides higher torque for maneuvering on uneven terrain or precise positioning. High speed optimizes travel efficiency when moving the machine across a job site or between locations. Operators can switch between modes based on the task at hand.

Hydraulic Control and Operator Interface

The machine uses a handle small-travel 8-way valve with two zinc-plated actuators and four cast aluminum foot pedals. A handle-operated ball valve provides quick oil circuit shut-off for safe attachment replacement. The control layout is designed for coordinated machine movements during digging and travel.

Engine Options: Kubota and Laidong

The HT20 Pro can be configured with a Kubota or Laidong diesel engine. The Kubota engine is known for low fuel consumption, low vibration, and stable performance. The Laidong engine offers high torque output and is designed for harsh conditions. Since stock batches may vary, please specify your preferred engine brand when inquiring.
