Crane boom, mast and base fabricated from heavy duty welded constructed structural steel pipe and tubing that limits deflection and meets ASTM standards.

Boom adjusts to three different angle positions.

Crane 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.

Electrostatic powder coated crane and stainless steel fasteners combine to resist corrosion in harsh environments. Other options available include: galvanized, stainless steel and epoxy finishes.

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.

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

Replaceable bushing and nylatron flange provide smooth and easy crane rotation while under load.

Quick-release clevis style stainless steel pins allow for easy assembly and quick disassembly for transport or storage. No tools required.

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.

Pedestal, flush, wall mount and wheel bases allow for a variety of mounting solutions and are easily installed. Standard powder coat finish on pedestal, flush and wall mounts. Wheel base features enamel finish. Other finish options available including galvanized, stainless steel and epoxy finishes.
