300 Ton All Terrain Crane
Superior performance
Powerful lifting capacity
The 300 ton all terrain crane features seven-section boom made from strengthened steel and optimized U-shaped section with maximum boom length of 80m and fixed jib of 42m, which translates to a maximum lifting height of 112m and maximum working radius of 80m.
The 0°-40° automatic infinite variable luffing jib allows you to easily switch among all operations.
High Efficient Hydraulic System
The converging flow of the single-action dual-pump ensures fast operation and high work efficiency, while the combined-action dual pump diversion system gives you stable control of the crane.
Electric proportional variable displacement piston pump ensures highly accurate flow control with higher efficiency.
Excellent traveling performance
The innovative 6-axle chassis design with six driving modes and four braking modes provides reliable travelling ability. The all-terrain crane adopts tipping over early-warning technology to guarantee high stability and safety.
Safety and Stability
Intelligent electronic control
The advanced distributed integration bus data communication network and the sensors on the control system provide real-time feedback and data analysis, making you informed of the 300 ton all terrain crane’s situation all the time. The human-computer interaction interface makes it simpler to interact with the crane and allows safer operation.
More safe devices
Hydraulic system is configured with the balance valve, overflow valve and two-way hydraulic lock etc., ensuring stable and reliable operation; Main and auxiliary winches are configured with 3-wraps protectors to prevent over roll-out of the wire rope; Boom and jib are configured with height limiters at ends to prevent over-hoist of the wire rope.
