Portable Davit Cranes FAQs
Absolutely. All portable davit cranes have versatility in reach, capacity, height, crane size, and more. The user can leave the crane in the base permanently if desired.
Yes, Thern can offer 4WP, 477, and 3WG4 models with pneumatic motors to mount on davit cranes.
Absolutely. Thern offers rotational bearings with our portable davit cranes that serve two primary purposes: 1) They aid in crane rotation during use to make workers’ duties easier and safer. 2) The bearings have a series of positional locks every 30 degrees, so the crane can be locked in position at any time—whether in use or not. Given the extreme conditions on an oil rig, this is a great accessory to pair with Thern portable davit cranes for added safety.
Thern’s 5PT10 and 5PT20 Commander® Series davit cranes have a 4WP2T model electric winch option available for these long lifts. This unit has a larger drum to accommodate more cable for lifts of 150 feet and longer. Crane load ratings over extended lift distances may change slightly depending on the extent of the lift distance, so we encourage you to contact our technical sales team to discuss the specific details of your application so that we can recommend the best davit crane and electric winch combination for your long-lift needs.
Several of Thern’s standard crane models can be used as a small vehicle-mounted crane. Additionally, Thern’s Workmate, a hitch-mount davit crane base, was specially designed to be compatible with a standard 2″ receiver hitch. The Workmate allows customers to have a crane attachment for a truck, and it can be situated on the ground behind or to the side of the associated vehicle.
Yes, a portable davit crane can be used as a stationary davit crane. A portable crane does need to be moved to other davit crane base locations if the application does not require it.
This is to aid in the portability of the davit crane from one application to the next. Rather than unhooking the wire rope from the load, you can simply disconnect the wire rope from the winch using the quick disconnect feature, hook it in the key-hole slot on the gusset of the base or an optional rope keeper, and move the crane to a different base location. This feature improves the safety and efficiency of operations by allowing the wire rope assemblies to remain connected to the load and eliminates “fishing” in less-than-optimal conditions.
