Pfanzelt Loading Cranes, Top-Mounted Boom Cylinder
Pfanzelt's loading cranes with a top-mounted main boom cylinder, where the cylinder is protected from damage when handling timber: ten sizes from 6.62 to 9.95 m of crane length and 52 to 86 kNm gross lift moment, for forwarding trailers and trailer chippers.
- Ten sizes, 4167 to 61100
- 6,620 to 9,950 mm crane length
- 52 to 86 kNm gross lift moment
- Main boom cylinder on top, protected when handling timber
- Single or double telescope; 4.5 or 6.0 t infinite rotator
Overview
Pfanzelt builds its loading cranes in two versions, which differ in the position of the main boom cylinder. On these cranes the cylinder is mounted on top of the boom, which protects it from damage when handling timber. They are used on forwarding trailers and, thanks to their slewing gear and choice of column heights, on trailer chippers.
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
