Features And Ratings - Bulldog DCH Serie Manual De Instrucciones

Load Rating
Load and speed varies according to how much wire rope is on the drum. The first layer of rope on the
drum delivers the slowest speed and the maximum load. A full drum delivers the maximum speed and
the minimum load. For this reason, all utility duty hoists are rated at their first layer capacities.

Maximum Drum Capacity
The flanged drum end plates shall protrude beyond the rope wound on the drum at the top layer by at
least 1.5 x the nominal rope diameter.
Rope Safety Factor
The working coefficient shall be determined from the ratio of the minimum breaking force of the rope and
the maximum possible lifting force.
* In compliance with standard ANSI B 30.5, the rope safety factory shall maintain at least 3.5:1.
D/d Ratio
The drum diameter to wire rope diameter ratio (D/d) determines the wire rope size required. Minimum
hoist drum root diameter = wire rope diameter x ANSI B 30.5* ratio minus rope diameter. The greater the
ratio the longer the wire rope life.
* In compliance with standard ANSI B 30.5, the D/d Ratio shall maintain at least 18:1.
