Rope anti-corrosion measures introduced
Rope corrosion : There are two kinds of anti-corrosion coating oiled and measures .
Oiler : All rope must be oiled . Fiber core immersion oil , grease required to protect the fiber core
does not rot , does not rust steel electric hoists for sale, moist fibers, and lubricate the rope from
the inside. Greased surface so that all the surface of the wire strands are evenly coated with
anti-rust lubricant , in which the friction and enhance a large mine mineral water with a rope , to
increased wear and water resistance coating strong Heiyou fat ; alternative use is strong film
-coated , rust good performance marked fats and require oil thin, easy to keep clean during
operation .
Plating: galvanized , aluminum , coated nylon or plastic. Thick coating of galvanized steel and
plated after first pulling a thin coating and galvanized steel wire after pulling thick coating
mechanical properties than smooth rope has decreased, should be used in severe corrosive
environments. Aluminum wire rope is more resistant to corrosion, wire rope electric hoist
abrasion , heat-resistant than galvanized steel wire rope is mainly used for fishing trawl vessels
and mines containing H2S , etc. , using the pull after plating production . Coated nylon or plastic
coated wire rope of the two co- rope after rope and coated stocks . The former is used for static
rope , which is used for moving cable .

Inverter controlled (BP series ) cable reel works and Scope
a. works
BP series frequency controlled motor cable reel is the world's most advanced mobile transport
solutions to meet the needs of any complex conditions . According to the formula F = T / R can be
seen ( where F is the cable tension , explosion proof wire rope hoist T is the torque roll rewinding ,
R is the radius of the drum winder ) , if they can be adjusted according to changes in roll diameter
roll rewinding torque you can achieve constant tension cable .
BP Series cable reel under closed loop vector inverter ( speed sensor vector control ) , select
open-loop torque control mode, and calculate the actual volume diameter cable reels integration
through the thickness accurately control the output torque of the motor , thereby ensure that
the cable wound on the reel , the winding radius changes automatically according to the torque
adjustment ( linear change ) , crane machine parts to ensure constant tension cables , protect the
cable to the maximum extent .
b. Features
1 , high integration , high intelligence , fast response , and device synchronization performance
accurate, sensitive .
2 , both in the closing cables, put the cable , both devices run on any position on the track , the
role of the tension on the cable is always constant , and can be controlled through the inverter
input parameters and operating knob counter version , any adjustments to maximize protect the

cable , effectively reducing the user's maintenance costs.
3 , breaking the bottleneck of traditional cable reel design hysteresis torque motor type, etc. ,
without cable specifications , winding length , speed and installation of equipment specifications
extraordinary height restrictions , quayside container gantry crane any complex conditions of the
cable reels are by a different variable frequency motor drive power .
4 , adaptable , can work under high load under full-time , stable performance ;
5 reels and equipment for the operation of the interlocking protection, effectively prevent the
cable is pulled off and other accidents.
c. Control
BP Series cable reel control systems and equipment relatively independent , according to the
actual control cabinet can be mounted in any position ( indoor or outdoor ) , just power from the
main power switch leads , or total output of AC contactor device connected to the control box
empty can be opened .
d. Scope
Can satisfy any sophisticated mobile power requirements applicable to gantry , bridge , gantry
cranes, stacker reclaimer , crest door , bridge crane , bridge games , loading and unloading ship
machine , metallurgical machinery , hydraulic machinery and mining machinery and other large
equipment to move the rail line power and data transmission.
