Slewing Drive

Slewing drive, planetary gearboxes

Self-raising tower crane is manufactured by means of combining introduction
of foreign advanced technology with the experiences. We got from operation if out
own-designed tower crane for several decades. Novel in design, the structure is
ration. Adopt Q345B by part strength mainly, body of the tower adopt self-centering
and non-welding joint; slice of type structure made up of eight to connect
to have by oneself to adopt, it is rational to receive strength, the craft is good,
transport it conveniently, the installation rate is fast. Adopting the roof
beam of upper and lower crosses to support, the regular center of clamp carries
the new organization rising, it is safe and reliable. It is hoistway organization
it has to be heavy to get up weight, it is rise steady, hoistway speed fast and
transfer speed range wide to get up to get up, install and take one is place
the convenient, high advantage of working efficiency. Slewing parts adopt OMD step
less to transfer speed, guarantee starting, is it take one is place accurate
steadily to apply the brake to construct to transform to go back. Troll eying organization urge by many speed electrical machinery decelerator through electric
to is it realize 3 speed of stabilizing to control directly, it is maintained conveniently
that fault rate is low. Traveling makes up main drive bogie in the organization
by 4. 4 bring double of disk type two speed electrical machinery of brake
urge decelerator is it guarantee through electric apparatus starting apply
the brake steady various kinds of complete safety device to control, moment limiter,
heavy working load and speed limiter most, is it rise degrees of limiter, turn
limiter round, become pieces of limit location device, walk limit location device,
etc. to get up. And can allocate the moment display of liquid crystal according
to user is request. Tower machine this is it rise, turn round, become piece,
can is it exchange frequency conversion transfer speed technology for users
to choose to select for use to get up.

4. The tooth profile of the output gear is crown gear which can assure the normal coupling when the town crane is deformed as loading.

3. Adopting hydraulic coupling and electromagnetic brake, it can start smoothly as well as brake rapidly and reliably.

2. The planetary with a close structure and lubricated with lithium grease is easily maintained.

1. Can be equipped with Y series motor or YD series multi-speed motor to change speed according to customers requirements.
