Introduction; Performance - Spinlock XX Série Mode D'emploi

Introduction

Spinlock are the experts in high load rope holding. These
high load models are designed to match the advances in
high strength ropes. With their unique wedge action they
will hold expensive sheets and halyards safely and securely,
with low risk of damage.
Products in the high load range include the ZS Alloy, ZS
Carbon, ZS Open Jammers and XX Powerclutch, holding
ropes from 8mm to 32mm and loads up to 12000kg.
High Load products included in this instruction booklet
include:

ZS1014B and ZS1618B are supplied designed for bonding directly
onto spars, booms and decks (see page 17).
ZS1214, ZS1014C, ZS1014B, ZS1618C and ZS1618B are supplied
with jaws and rear blocks prepared for use with 'ZS-RLB' Remote
Lock Back Switch allowing pre tensioning of the jaws for release
and remote operation of the jammer (see page 18).

Performance

The ZS and XX range of clutches and jammers are designed to generate
high compressive loads on the rope to ensure the core bears the greater
part of the load without over stressing the polyester or other fibres of
the outer braid. The structure of the jammers and clutches can withstand
loads beyond the stated max holding load. The data shown, represents
the maximum SWL we recommend for each product for a given diameter
with polyester covered ropes.
The actual load achievable can vary considerably according to the quality
and construction of the rope used. Before selecting the rope to use in
the product, check:
• The actual measured diameter under load.
• That the rope cover includes polyester - Vectran, HMPE (Dyneema,
Spectra) or PBO cannot be gripped on standard jaws, unless
blended with polyester.
• The cover is a close fit on the core with an interface layer or fibre
coating. Nominal section should be round.
• Sleeved areas are fully pre-tensioned with smooth entry and exit
tapering.
• The load rating for the rope and safety factor recommended by the
rope manufacturer.
Recent development in rope manufacture has centred on the use
of blended covers, where high tech fibres such as Aramid, Technora,
Dyneema or Vectran are co-braided with polyester or polypropylene.
Whilst hardwearing, with a high degree of heat resistance, these covers
can be harder to hold in clutches or jammers compared to polyester
covered lines. Contact the Special Projects Team for advice on new
digital custom jaw surfaces to suit specific blended covers or see
page 34 for spares and upgrades.
