JCB 820 S-LC - Product Description

Drive and Construction

The JCB 820 S-LC excavator is powered by a Perkins engine, model 6.354 T, delivering 103 kW, a typical output for mid-weight crawler excavators. The diesel engine reflects JCB’s standard engineering approach for machines in this class, emphasizing durability and serviceability. The machine features a Long Crawler (LC) undercarriage configuration which improves stability under load and in uneven terrain. The operating weight of 20.1 tonnes places it in the medium-to-heavy segment among crawler excavators.

Undercarriage and Hydraulics

Equipped with 600 mm wide tracks, the LC undercarriage of the 820 S-LC allows for reduced ground pressure and enhanced traction, particularly useful in softer soils. The hydraulic system works in a conventional manner, controlling boom and bucket operations with precision. There is no standard fitting of hydraulic quick couplers or mechanical ones according to available documented data. Because critical figures such as digging depth and reach are not documented in reliable sources, they are not included.

Operating Parameters

The bucket capacity is 0.8 m³, a common value facilitating effective spoil removal and loading operations in many construction tasks. At an operating weight of 20.1 t and a power of 103 kW, the machine is capable of handling typical workloads expected from machines in its weight class. Track width of 600 mm contributes both to stability and manoeuvrability, especially on less stable ground. These verified parameters define the core working capabilities without reliance on unconfirmed data.

Optional Equipment

According to reliable spec records, this model is not factory-equipped with a diesel particulate filter, blade, operator cab adjustment, front cutting edge, material handling arm, air conditioning, hydraulic or mechanical quick couplers, nor track gauge adaptation. Such features, however, are commonly offered as aftermarket or optional factory fitted equipment on machines in this category, depending on the region and user requirements. Retrofits may include cabin climate control, quick couplers, or specialized attachments to expand utility.

Safety and Technical Data

The structure of this crawler excavator typically includes safety features in the operator cabin and frame, often complying with ROPS/FOPS standards, though specific certification data is not documented for this model. Perkins engines are well regarded for reliability and maintenance availability, which contributes to operational safety and uptime. Transport dimensions such as length, width, and height are not specified in reliable sources, limiting logistical planning. Absence of emissions level data or noise certification means users must verify compliance with local regulations before deployment. The LC undercarriage and overall mass contribute to stable operation in challenging worksites.
