Welded Steel Construction
Crane boom, mast and base fabricated from heavy duty welded constructed 6061 aluminum pipe and tubing that limits deflection and meets ASTM standards.

Adjustable Boom
Boom extends to four positions with quick-release pin and adjusts angle with ratchet.

Manual or Power Operation
Thern davit cranes can be configured with a manual winch for short, infrequent lifts or a power winch for longer lifts or heavier loads. Choose from Thern’s spur or worm gear hand winches or power winches with 115/1/60V as well as pneumatic, hydraulic or DC Volt power operation.

Corrosion Resistant Finish
Electrostatic powder coated crane and aluminum fasteners combine to resist corrosion in harsh environments. Additionally, an epoxy finish option is available for environments prone to corrosion, further enhancing its longevity in harsh conditions.

Easy Assembly/Disassembly
Quick-release hardware and pins allow for easy assembly and quick disassembly for transport or storage. No tools required.

Quick Disconnect Anchor
For quickly attaching or removing wire rope equipped with a swaged ball fitting. Allows the operator to leave the wire rope attached to the load at all times and simply remove the rope from the winch and attach to the optional wire rope keeper or cable reel.

Sheave Clevis Pin
The sheave clevis pin is D-Shaped to prevent the clevis pin from rotating when under light loads.

Quick-Mount Winch Bracket
A variety of Thern winches can be attached to the bracket. After a winch is attached, the bracket is easily mounted (without tools) to the crane via quick-connect pins.

Mast Cap
A cap on top of the mast helps keep weather and debris out of the mast.

Rotation Handle
The new rotation handle position does not interfere with the operation of the boom angle adjustment screw jack.

360º Rotation
Nylatron bearing allows smooth and easy 360° crane rotation under load.

Variety of Bases (sold separately)
Pedestal, flush and wall mount bases allow for a variety of mounting solutions and are easily installed to a variety of solid surfaces with anchor bolts or other fastening methods. Bases sold separately. Base cap included with lanyard keeps water and debris out of base when crane is removed.
