X Roller Fairlead
The use of 4 ways roller fairlead can eliminate the contacting friction
because the fairlead rollers contact with the wire rope. But the
fairlead does not insure the wire rope will wind onto the drum in an
orderly manner. The proper fleet angle within 15° must be
maintained for the wire rope to wind onto the drum in an orderly
manner. If the proper fleet angle is not maintained, it can result in
damage to the winch and wire rope.
X Hawse Fairlead
The basic hawse fairlead is designed to guide the synthetic rope to
and from the winch drum. Do not use cast steel hawse fairleads as
they have sharp edges and they do not have enough radius for the
rope to bend over.
X Recovery Damper
A recovery damper is a safety device designed to help
eliminated the possibility of injury or property damage in the
event of a wire/synthetic rope failure. Place in the middle third
of a live rope. The damper can help absorb the energy in the
rope and reduce the likelihood of injury or damage.
X Snatch Block
An important aid to successful winching is the use of snatch
block, which can be used to increase the pulling power of a
winch or change the direction of a pull.
A winch double lined with a snatch block creates a
mechanical leverage cutting the effort required by nearly half.
The double line pull shows self recovery using a snatch block
attached to an anchor point; the pull applied to the vehicle is
almost twice as much as the line pull of the winch.
The use of one snatch block shows an indirect pull where the
vehicle is limited due to unsuitable ground or obstruction. The
pull on the load is the actual line pull of the winch. If more
than one snatch block is used, they must be located at least
100 cm (40″) apart.
