LIFTING :- Operator is shown raising the load by simple vertical pull on the
rope
LOCKING :-
When the rope is moved in an outward direction the lock comes into
instant operation.
LOADING :-
With the load securely sustained the operator can concentrate on the
traversing or loading. Load can be released immediately by a vertical pull on the rope.
DESIGN, FEATURES &
SPECIFICATIONS :-
ROPELOCK PULLEY BLOCK :- There are many uses for the Ropelock
on building and erection jobs due to its lightweight and sturdy construction, and in this case heavy concrete slabs are being
taken to an upper floor.
Handling of oil drums is simplified
by the use of this ROPELOCK Block on a S. Crane. Underslung Hand Pushed Crane.
The Ropelock Pulley Block is a
manual lifting equipment incorporating a unique locking device which enables the load to be raised, locked and unlocked with one
rope only. The locking system is controlled by the direction of the rope as
illustrated. Heavier the load tighter is the lock. The locking device is adjustable so that
the locking action can take place with a wide range of movement.
A few of its notable features are as
follows :-
1) Low headroom to achieve
maximum lift.
2) Light weight to make it useful for erectors and maintenance
Engineers.
3) All the models given above can be used with equal ease in a
vertical, horizontal
or angular position.
4) Speed is the asset of this equipment where it scores over
conventional chain pulley blocks. For the same
capacity that is 500 kg. where one has to pull 52
meters length of chain to lift the
load through one meter in an ordinary chain pulley block, in our RL - 4 model
one has to pull only 4 meters of rope length to lift the load through one
meter. Standard rope is GARWARE P.P. but nylon and terrylene ropes are
available
for special applications.
5) Standard Lifts available are 6 M & 14 M, however,
higher lift blocks can be supplied on request.
The Ropelock Pulley Block can be
used in any & every industry, shop or Godown
where materials more than 50 kg. need to be handled ( 50 kg. being the
average max.
weight a man can carry)Its light weight construction makes it
easy to install.
We at S. CRANE would be glad to
assist you in designing & installing overhead structures & supports to ensure safe, smooth & economical
materials handling for
your
applications.
Hoist
Motor :- Specifically designed for high starting torque hoisting service,
half-hour rated with permanently lubricated
bearings suitable for frequent reversals as well as braking.
Hoist
Brake :- The Hoist Brake is fitted with an electromagnetic brake designed
and
built to arrest and hold safety
the full load capacity of the hoist. The brake provides
a fail to safety feature and
failure of current immediately applies the brake.
Bottom
Block :- Full rotating lower hook is high strength forged steel. Thrust
bearings make swiveling easy even under load.
Gearing :-
Spur & Helical Gears cut from alloy steel and duty heat treated as
required are used in totally enclosed casing
to provide grease lubrication. Newer design are lighter weight because
of improved material strength manufacturing techniques.
Electrical
Components :- All electrical controls are centralized within one
enclosure with
removable cover to access for easy
servicing. Control circuit provides reduced voltage at the Push Button station,
with 110 volts being standard. Under
the new control system, operation is
often much more gentle on components, lowering shock loads and heat
build up.
Limit Switch :- Positive action limit switch will prevent over travel
beyond set limits in either direction. (
Optional is desired for CT and LT ).
Push
Button Station :-
Weather proof as standard, giving sure grip, one handed control. Station has built in steel strain
relief, permits pulling of unloaded hoist
along track.
All components generally designed in compliance with is-so 7 &
is-3177
