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, XX, XXB and XXC Powerclutch, holding ropes from 8mm to 32mm and
loads up to 12000kg.
High Load products included in this instruction booklet include:
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 or cover. The structure of the jammers and clutches can
withstand loads beyond the stated max holding load. The data shown, represents the maximum
safe achievable holding power 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.
• Other cover blends can be successfully be held with ceramic jaw sets.
• 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.
See Page 36 or contact
the Special Projects Team for advice on custom jaw surfaces to suit specific blended covers,
including high line speed protection.
ZS1014B, ZS1618B and XXC0812/HBP/HBS 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).
