electricity Power capstan

In practical application, we may be very curious: why is electricity Power capstan motor inside the small, but can be a car Pulled from the mud? This will be referred to the use of reducer The motor, even if a force is small, but the reducer can single girder It will be transformed into a powerful force, this principle is used to work. Electric winch working mechanism of internal is through the vehicle electrical Force drive motor, and then drive drum, a rotating shaft, planetary gear monorail wire rope hoist A series of parts and products, strong torque, when the torque is back to the drum, ultimately drive the winch operation, The reducer winch is used in most of planetary gear, advantages of this component is very obvious, although small, but The reduction effect is very big, and the service life is longer, usually installed in a narrow space, therefore it is small Features on the show. In addition, between the motor and the speed reducer and a manually controlled clutch,SSDHL electric chain hoist We can directly control, and braking unit in the drum interior, when the noose taut, the drum will be automatically locked.

Ring chain electric hoist is introduced and the scope of application:


Ring three phase electric hoist weight is generally 0.1 ~ 60 tons, lifting height of 3 to 120 meters, the characteristics of electric chain hoist: performance of advanced structure,small volume, light weight, reliable performance,
three phase electric hoist
convenient operation, wide application range, is very convenient for lifting, loading and unloading, repairequipment, hoisting goods, it can also be installed on a suspended steel, curve track,jib crane rail and fixed lifting hoisting heavy weights.
Structural characteristics
1.5 ton electric chain hoists electric hoist structure characteristics: the product structure: the selection of high strength tensile shell or die cast aluminum housing, with a thin wall extrusion molding process of precision manufacturing, small volume, light weight, high strength. Standard forpower chain hoist with gearbox system independent, two coaxial transmission gears sealing transmission, using long-life oil bath lubrication system. Electric hoist overload protection device of powder metallurgy clutch, brake disc DC electromagnetic brake use, large braking torque, stable, fast, low noise.

it must be manufactured in accordance with the elevator specification.

 it must be manufactured in accordance with the elevator specification. The specification requires a minimum diameter of the roll is drawn 35 times the rope diameter , which is in the choice of type and structure should be taken into account. Grain elevator car 's exterior features is having a hand wheel ( 20 ) , you can use it to complete the current is interrupted when lifting and lowering movement. To this end , the elevator must be installed in a manual brake release means which enables the tension of the brake spring against the brake current is interrupted.SWF 's new elevator winch from the weight of 500 kg slaughterhouse used by a winch is bolted by foot "U" shaped beam chassis electric hoist structure, it 's two points to both sides of the rope , Ken rope hanging from a beam ends ( 21 ) also known as lateral sliding winch winch is a standard type ( with a foot bolts ) , but there are two separate split a rope . Its two rope is wound on the reel so career : When a rope to relax, another rope around tight. Rope reel slot is continuous ( L or D ) . Each rope has a row of rope . Two parallel rows of rope attached , and make parallel movement ( 2 ) in the same direction with the longitudinal axis of the roll . Electric hoist with other machines, but also repair and maintenance. But unfortunately, the machine contrary , hoist repair and maintenance is often neglected , especially those where tetrahedrite occasional use of electric hoist . In addition, because it is hung aloft ( especially fixed suspension )

Manual Hoist specifications of the hoist rope securely fixed

 With the provisions of models, specifications of the hoist rope securely fixed . Hand hoist wire rope , synthetic material is generally metal , so it must be done in full respect of maintenance , in order to not affect the normal use of the device . Usually comes with electric chain block a conical squirrel cage rotor brake motor (or reprovision cylindrical electromagnetic brake rotor motor ) drive , weight is generally from 0.1 to 80 tons , lifting height of 3 to 30 meters . In addition to electric hoist can be used alone , but also with manual or electric car chain assembled together , hanging in the roof of the building or crane beam.

Electric hoist is a remarkably versatile small light lifting equipment . No need to add oil to use in the monorail trolley operation , are not allowed to use other than to replace the rope with a supporting rope ; operation, the rope should be kept clean to prevent the adhesion of mud and oil into the machine , affecting the normal use or wear and tear plus clamp . Electric hoist, electric hoist short . Most electric hoist used by people on the ground following the manipulation button can also be manipulated or wired ( wireless ) remote control in the cab .
