Structure outline
The  KTJ15A, B series exchange cam controller protection rank is IP30, uses the vertical installment.
The controller divides four parts: Control mechanism partial, the cam and the contact systematic part and the shell are partial. Its control handle, for avoids because the hoist crane vibration and the accident collision causes the control mechanism misoperation, this handle has the self-locking installment. When operation, only must press the handle, the zero position self-locking installment opens, then may operate.
The mechanical drive department loads separately on the box body, the vertical operation handle is after the bevel drive cam shaft, the level operation handle then is the through drive cam shaft, causes the contact group according to the stipulated procedure analysis and synthesis.                                                              The controller cam shaft is the vertical installment.                                                                                   The contact arrangement except KTJ15B-32/2, 6,3/2, 3,2/5, 6,3/5 for the two-row arrangement outside, other is the single line.                                                                                                                                    The transmission partial various pivots use the rolling bearing, by to reduce the friction force.
Locates the notch wheel is but becomes by 3 millimeters steel plates ramming, and obtains the good resistance to wear after the suitable heat treatment. The controller files figure is a fifth gear. In the about various fifth gears scope, the files figure may choose wilfully.
The localization ratchet spring strength is may adjust, like this may act according to the special details, under the classifying clear premise, adjusts the ratchet spring strength to cause the handle control force in the permission scope.
The cam suppresses for the black phenolic plastic but takes shape, its structure for puts on the ventricle, like this had guaranteed the rigging position is accurate.
Contact group structure for rotation type double break point. 32A and the 63A contact group installs the size to be same, therefore uses in common in installs the strut. The seat-s on a plane uses presses the
cast-aluminium, on the kneading board uses the steel plate to stretch takes shape, the seat-s on a plane and the pan connect a body with 4 props, has the weight to be light, the rigidity good characteristic, around the shell can facilitate dismantles, for the installment, matches the line and the service uses.

Use and servicing
   7£®1¡¢Controller application installment screw retention. Makes an effort under to the vertical handle a handle lever insert operation turn of hole in to push, the localization locks then can automatically lock
in, then then operates.
   7£®2According to the electrical schematic diagram request, chases the files operation controller separately, observes the contact the analysis and synthesis whether the contact analysis and synthesis procedure does tally with the wiring diagram in.
   7£®3Must inspect the electric motor in front of the circular telegram with the resistor related electric system wiring is whether correct, earths whether reliably.
   7£®4After receives a telegram should according to the corresponding controller careful inspection electric motor movement situation, after if has the difference to be supposed the dump to treat immediately verifies the reason only then to continue the circular telegram.
   7£®5The controller should request according to below to inspect the service frequently:
   7£®5£®1All bolts joint are partial must fasten, specially contact binding post screw;
   7£®5£®2Rubs partially should maintain the certain lubrication frequently;
   7£®5£®3The contact active face should not have the obvious melt spot, burns the melt the spot to be possible to use the smooth file careful repair, does not permit the use sandpaper.
   7£®5£®4The damage components must promptly replace.
