The Braden Winch CH series of planetary hoisting winches offered by Winches Inc provides application flexibility through optional features and accessories, enabling the product to be tailored to meet specific requirements.
Braden Winch introduced its first CH Series planetary hoisting winch to the offshore industry more than 40 years ago. Since then, the CH Series has undergone two major design changes improving its performance and longevity.
The key features of the current third-generation CH Series planetary hoisting winches include: a robust ball-bearing overrunning clutch allowing increased input speed and superior fall-back protection; a robust, time-tested, spring-applied, hydraulically released internal brake designed to give years of consistent braking; and highly efficient, superior-quality planetary gearing for maximum efficiency and a long service life.
The true value of the robust CH Series is in the application flexibility, breadth of the product line and the optional features to tailor the winch to meet specific requirements. What follows are some of the many options and accessories available to enhance the CH Series.
Braden offers some CH Series models with grooving cast into the cable drum. On all other models, grooving can be added by installing a sleeve over the standard smooth cable drum. The grooving on a cable drum supports proper spooling of the first layer of wire rope on the cable drum. A proper first layer is a key factor in ensuring all other layers spool correctly. In applications when the bulk of the winch work is done on the first layer, grooving is a must.
Each CH Series winch can be equipped with a tension roller to assist with proper spooling of the wire rope on the cable drum. The primary function of a tension roller, also known as pressure roller, is to keep constant pressure on the wire rope as it spools onto the cable drum. The constant pressure enhances spooling, especially when the wire rope is slack. Improved spooling increases the life of the wire rope, saving time and money.
All CH Series models are available with an auxiliary brake. The Braden auxiliary brake is a fully enclosed, spring-applied, hydraulically released friction brake acting directly on the drum. The sole function of this third redundant brake is to provide a means to stop a load should the counterbalance valve and internal brake fail.
As drill rigs move further offshore, the winches are required to hoist over longer distances. Braden has released dual-motor inputs on some of the larger CH Series winches. Dual motors provide additional torque for high load requirement but also allow greater line speeds, which increases efficiency as loads get from boat to rig much faster.
