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,

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 .

hoist equipment mast distortion correction method can be eliminated

Electric forklift mast distortion correction method can be eliminated. When bending and twisting deformation is small, allowing the cold calibration correction method applied motorized chain hoist static load . When bending , distortion is too large, correction is difficult to use cold , heated correction should be heated to minimize the heating zone , the heating temperature is generally not more than 700 ℃, and slowly cooled so as to increase brittleness.three phase electric hoist mast crack repair : If the inspection found cracks should be repaired .repairs should be carried out before the forklift mast correction , maintaining the inherent straightness mast .grinding cracks to expose the metallic luster , and then carefully examined to determine the boundaries of the crack extends 10mm at the boundaries of the drill ¢ 5 - ¢ 8mm of limiting, holes.

Manual Hoist it selected for intensive applications

With a range of quite different , it selected for intensive applications , the various parts of the program  that is very closely coupled , such as word processing software, interactive graphics system . The VB and  Delphi (c + + builder and Delphi as Inprise company with products that use different languages ??in  addition to the remaining features almost identical ) code is very suitable for those large , multi-  interface , high degree of independence module , low coupling management system, especially with a large  database on the processing application . VB and Delphi are RAD (RapidApplicationDevelopment, rapid  application development ) development tool , which can greatly improve monorail trolley programming efficiency , but their  underlying code execution efficiency and flexibility , but not as good as some of the VC. According to the  characteristics of the test system , I chose to develop Windows2000 VisualC + +6.0 based monitoring and  control procedures. 4.3 Monitoring 4.3.1 test software development process control IPC is responsible for  the system test process control and management, but also to achieve a self-test function cargo belts of the system ,  and therefore , the test flow control sub-module is the key to the entire test module module , specific  processes such as Figure 4-1. The following brief description of what the testing process in several key  questions: ( 1 ) Although the test system has a self-test module , but in the entire testing process, the  test system is constantly monitoring the current state of each underlying device , if there are problems ,  issues the nature of the quick decisions and take appropriate measures to deal with . Such as laser  distance sensor error , the test software will automatically restart the device and prompts the operator
