JF Series: Articulated Cranes
Jekko JF Series Cranes at Foster Cranes
Foster Cranes supplies the Jekko JF series of compact crawler cranes. These machines are designed for versatility and reliability when working on jobs that demand precision, mobility, and compact footprint. Our JF series stock undergoes inspection and maintenance before delivery to ensure dependable performance and safety.
What Is the JF Series
The JF series consists of articulated crawler cranes with tracked undercarriages. These cranes combine the advantages of tracked mobility with flexible boom reach. The tracked base allows stable movement over uneven, soft, or rough terrain. The boom’s ability to articulate provides operators with adaptable reach and lift angles, making the JF series useful in a wide range of tasks and environments.
Typical JF Series Models and Features
Common features of JF series cranes supplied by Foster Cranes include:
- Compact footprint that enables access into confined areas or sites with limited space
- Crawler tracks for ground stability and safe movement over soft or irregular surfaces
- Articulated boom for flexible lift angles and variable reach
- Remote or onboard control options for precise load handling
- Capability to mount handling attachments such as glass manipulators, panel lifters or hooks for different project needs
These features make JF series cranes particularly suitable when space, terrain and flexibility are major considerations.
Ideal Applications for JF Cranes
JF series cranes are effective in many scenarios, including:
- Construction and renovation jobs where space is restricted or site access is challenging
- Installing structural steel, precast sections or building components in tight environments
- Glazing, cladding or facade work where precision and compact handling are required
- Factory or plant maintenance and installation where access is limited or floor loading must be minimized
- Work on uneven ground or remote sites where stability and mobility are necessary
