P&H 6350-TC

The P&H 6350-TC mechanical truck crane is a formidable heavy-lift solution, purpose-built for high-demand construction, industrial assembly, and infrastructure applications. With a maximum lifting capacity of 210 metric tons at a 7-meter radius using its 21.34-meter heavy-duty boom, this crane is engineered to handle the most challenging loads with precision and dependability.

Mounted on a robust multi-axle carrier, the machine has an operating weight of approximately 246 metric tons in standard configuration, including the base boom, four-piece counterweight system totaling 60,000 kg, a 7-sheave 210-ton hook block, and a full gantry mast. The crane can be configured with main boom lengths from 21.34 m to a maximum of 88.39 m using modular tubular T-1 lattice inserts. Optional jibs extend lifting height further, with lengths up to 24.38 m available in two-piece configurations, making it adaptable for tall and extended reach lifting.

The crane’s upper is powered by a Cummins NTA 855-C400, a 14.01-liter 6-cylinder turbocharged diesel engine delivering 400 PS at 2100 rpm. The boom hoist is independently driven via a planetary clutch and band-type brakes, offering line speeds up to 28 m/min in high gear. The system supports 20-part boom hoist reeving, critical for managing the immense loads this crane is capable of handling. Dual drum winches operate independently for main and auxiliary hoisting, using 34 mm and 26 mm wire ropes respectively, mounted on anti-friction bearings for longevity and smooth operation.

Swing motion is provided through two electro-magnetic Magne-Torque units delivering a maximum swing speed of 1.5 rpm, with full control via band-type spring-set hydraulic brakes. The high gantry structure, essential for boom support, folds automatically and is hydraulically assisted for easy setup and takedown. Operator comfort is maintained through high-visibility cabs with access panels, all-tinted safety glass, and optional heating and cooling provisions.

The carrier is driven by a Cummins KT-450 engine rated at 450 PS, coupled with a power shift transmission offering six forward speeds, integral retarder, and an auxiliary air-shift transmission with four speeds. This setup ensures highway travel speeds up to 75 km/h and gradeability of 19.7% under load. It includes heavy-duty planetary drive axles and solid tridem Hendrickson suspension with 18 off-highway tires (14.00 x 24 – 24 PR).

Outriggers are independently extendable with hydraulic horizontal and vertical control, supporting maximum stability with a span of 4600 mm from the carrier centerline. The crane’s swing circle features a roller bearing-type connection with internal teeth, ensuring secure rotation and modular detachment for transport.

Rated at 78% of tipping load, the 6350-TC offers an extensive lifting chart up to full boom configurations, with detailed reeving and hook block arrangements. It accommodates hook blocks up to 210 tons (7 sheaves) and offers multiple reeving options from 2 to 20 parts for optimal load handling efficiency.

In conclusion, the P&H 6350-TC is a mechanical powerhouse that prioritizes raw lifting strength, field serviceability, and modular adaptability. Its proven mechanical systems and robust construction make it a trusted asset for heavy-duty lifting on critical job sites.
