Winch Configurations
Welded Steel Construction
Crane boom, mast and base fabricated from heavy duty steel that limits deflection and meets ASTM standards.
Manual or Power Operation
Thern davit cranes can be configured with a spur or worm gear manual winch or power winch. Choose from Thern’s spur or worm gear hand winches or power winches with 115/1/60 as standard. Other voltages available as well as pneumatic, hydraulic or DC Volt power operation. Worm gear hand winch configuration can be drill-driven.
Mast and Boom Rotate
A tapered roller bearing allows for smooth and easy 360° crane rotation under load. Mast locks in one of four positions with hand-tightened lock bolt. Rotational handle located on mast for easy rotation.
Corrosion Resistant Finish
Red enamel finish resists corrosion in harsh environments. Epoxy finish also available.
Two-Year Warranty
Industry-leading two-year limited warranty on all our products.
WARNING: Prop 65: Products supplied by CERTEX USA may expose you to chemicals including Nickel, which is known to the State of California to cause cancer. For more information, visit to www.P65Warnings.ca.gov.
The dynafor® HHD is a complete and versatile handheld display.
Universal, the dynafor® HHD can be connected to our dynafor® Pro, dynafor® Expert and dynafor® Transmitter WL. Up to 4 units can be simultaneously connected.
Equipped with a colour-LED display, the dynaforTM HHD can reach a wireless range of 1,300 ft. (400 m). The dynaforTM HHD offers multiple functionalities, suitable to any application.
The dynarope® tension meter is a precision device for measuring forces in a tensioned cable or rope. The meter can be attached directly to the cable and has a fixed display.
When the tension meter is placed on a tensioned cable, the load cell will generate a signal which is more or less proportional to the force.
The HF 37 series can be connected to a PC for managing and storing measurement results.
There is a large variety of cables, each cable having its own characteristics such as composition, diameter, rigidity, density, etc. The database includes several basic wire rope data. We are happy to help you choose the right model and parameter settings in our wire rope database.
The dynarope® HF 36 is an electronic load cell that has been designed to measure the effort applied in a wire rope. The resulting signal is used in a digital remote display (model HF 87/T/LPT) controlled by a microprocessor, which corrects the force information according to the wire rope specification and displays the result of the measurement on a LCD display.
Several wire ropes specifications are logged in a data bank.
The dynasafe® HF 05 mechanical load cell has been designed to provide a trip point in lifting systems, which have a dead-end wire rope. The trip point load limiter generates an “all or nothing” type signal in the event the programmable target value is exceeded. Available in one or two thresholds versions.
The load cell is preferable for fitting applications where it is essential to minimize the lost headroom.
