BRADEN Winch introduced its first CH Series planetary hoisting winch to the offshore industry more than four decades ago. Since then, the CH series design has under gone two major design changes, improving its performance and longevity. The key features of the current third generation CH Series planetary hoisting winches includes:
- A robust ball-bearing, overrunning clutch, allowing increased input speed and superior fall back protection.
- A super durable, time tested, spring applied, hydraulically released internal brake, designed to give years of consistent braking.
- A highly efficient, superior quality planetary gearing system for maximum efficiency and a long service life.
The CH Series offers line pull ratings from 6 tons to 30 tons, but the true value of the powerful BRADEN CH series is in the application flexibility, breadth of the product line and the optional features to tailor the winch to meet specific requirements. Below is a list of some of the many options and accessories available to enhance the BRADEN CH Series.
Grooved Cable Drum
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 to ensure all other layer spool correctly. In applications when the bulk of the winch work is done of the first layer, grooving is a must
Tension Roller
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 a 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 in a slack condition. Improved spooling increases the life of the wire rope, saving time and money.
Auxiliary Brake
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 counter balance valve and internal brake fail.
Dual Hydraulic Motor Input
As drill rigs move further offshore, the winches are required to hoist for 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 for greater line speeds. Faster line speed increases efficiency as load get from boat to rig much faster.
Rotation Indicators
Most models can be equipped with rotation indicators and/or last rap indicators. On large cranes the winch is often not visible to the operator. Both rotation and last wrap indication are good methods to give the operator feedback on the current state of the winch. BRADEN has even offered a speed sensor, providing the operator with a positive vibration signal in the control joystick. The faster the winch line speed the faster the vibration felt in the control joystick.
Gear and Piston Motors
One of the simplest, most effective ways to increase the efficiency of a CH Series hoisting winch is to take some time to select the correct hydraulic motor. Different types of motor produce different results in the performance of your winch. Braden offers a wide selection of gear motors, gerotor motors and piston motors to tailor the performance of the winch to the specifics of any hydraulic system and application requirements.
