Pfanzelt 3-Point Linkage Cranes

Overview

Pfanzelt’s tractor cranes come for 3-point or quick-fit mounting. If the tractor is to be used flexibly, including with different trailers, the 3-point linkage crane with integrated stabilisers is the better choice. Three sizes are available, with a Pm230 gripper (1,260 mm opening) and a 4.5 t infinite rotator.

Slewing gear and geometry

Pfanzelt cranes have a robust 4-cylinder slewing gear; the high pivoting moment means loading work can also be done working uphill. The power link (toggle) system between the main and folding booms gives the crane its loading geometry, so timber can be placed directly against the headache rack, with constant force, more reach and a higher working speed. A rapid traverse valve, standard on every crane, extends the telescope about 1.5 times faster.

Hoses and bearings

The hydraulic hoses are concealed from the control block to the crane tip, laid in a hose shaft at points of high load and near the control stand, and the telescopic cylinder is mounted inside the boom. An optional pendulum with internal hoses and a double pendulum brake protects them right to the tip. All crane pins run in lubricated, hardened bronze bushes with adjustable axial play.

Control and options

Pfanzelt cranes come with a mechanical control block and two control toggles, each with an electrical switch, so the boom movements can be combined without changing levers. Options include:

• EHC control with a cord or wireless panel
• Two Danfoss Pro 1 joysticks on a rotary seat
• An independent hydraulic oil supply
• Crane floodlights
• A hydraulic oil cooler
• An operating hours counter
• A trunk scraper
• The exTEND crane cable winch (1.5 t, 50 m of cable, with radio control)
• Grippers for logs, branches, bulk material and round bales
