13.1.6 Fly Travel Distance
(1)
Standard travel is 18 m (59 ft).
13.1.7 Number of Lift Lines
4 to 7 lift lines are available on EVF-0509 model. 5 to 7 lift lines are available on
EVF-0901 model.
13.1.8 Braking
Primary brake is an electromechanical brake rated at a minimum of 150% of full load. Secondary brake
is a fully mechanical Weston-style load-side brake coupled directly to the drum rated at a minimum of
150% of full load.
13.1.9 Limit Switches
Direct-struck style, one up and one down, limit switches function as the second end of travel limit.
Ultimate over-travel circuit for maximum up and down end of travel disconnects power feeding the
motor/brake assembly.
13.1.10 Load Sensing
A pair of electromechanical load-sensing devices are designed to measure the load imposed on each
hoist. When activated, this data is used to protect against unwanted load changes due to overloading
or underloading the administrators' preset expected load.
13.1.11 Mounting
Standard units can only be mounted horizontally.
(1)
Double-purchase rigging doubles the capacity and halves the speed and travel distance.
