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 :-
ROPE LOCK 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 Rope Lock 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 Rope Lock 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
