Holt Winches Catalogue

Product catalog summary
Overview: The document provides technical specifications and features of a range of winches offered by Holt. These winches are designed to be low profile and lightweight, with the #44 model being 20% lighter than previous versions. Key features include roller bearings for stability, self-tailing and self-adjusting capabilities, and larger drum diameters for increased traction and efficiency.
Specifications: The winches are equipped with roller bearings or auto-lubricated synthetic bushings for all shafts. The off-centre axle design allows for more space for gears, providing greater mechanical advantage. The first gear is 15-25% higher, allowing for extended 'pumping' before shifting to the second gear.
Technical Data: The document includes a detailed table listing part numbers, fixing sizes, drum diameters, gearing ratios, weights, and other dimensions for various winch models. For example, the HT94066 model has a drum diameter of 220 mm, a weight of 15,000 g, and a gearing ratio of 45:1 in the first gear.
Key Features: - Roller bearings for stability
- Self-tailing and self-adjusting for various rope diameters
- Larger drum diameter for more traction
- Off-centre axle for greater mechanical advantage
- Lightweight design with aluminium and thinner walls

Holt Winches Catalogue-1

WINCHES A larger diameter in the drum means more traction on the rope and more efficiency in self-tailing. Larger internal body diameter allows the use of aluminium and thinner walls resulting in a much lighter part. Low profile and less weight, reaching 20% less in the #44. All winches bigger than the #44 present a roller bearing around the base resulting in a much more stable body, independent from the origin of the load. All shafts use roller bearings or highly-resistant autolubricated synthetic bushing. Self tailing and self-adjusting for a variety of rope diameters. Off-centre axle means more space for gears with the same base diameter the winch delivers greater mechanical advantage. This is a plus in high-load action and even allows the use of a shorter handle in lighter winds. First gear 1525% higher allows a longer period of ‘pumping’ before using the second gear.
