Product Description:

Introduction

On the basis of absorbing advanced foreign technology, our company developed the JXD trolley luffing mechanism independently for small and medium-sized tower cranes.

This series of trolley mechanism consists of electromagnetic double-speed change-pole motor, semi-concealed planetary reducer, drum, frame and other components.Its characteristics include compact sturcture, high driving efficiency, and low noise, safe and reliable braking, accurate positioning, pleasing in appearance and so on. When users have higher requirements to the trolley running, variable- frequency speed regulation motor with the same interface and relevant electric contol system may be changed to form the variable-frenquency speed regulation trolley mechanism.

Q:Can Ichabod Crane defeat the Headless Undocumented Worker before he prunes someone's bushes into hedges?
It's people like you who are the reason the governor of our state had to declare a STATE OF EMERGENCY to get federal help to stop these people from coming here. You do not understand the problem because you ARE the problem.

Q:Is there a crane lifting chart where I can enter info. to determine what size crane I need, if so where?
the 1st answerer, Irv S, is right. You need to call a craning service. They should be able to give an estimate for crane size based on what you tell them. You will need to know what your Load weighs. How high in the air the crane will have to lift it. ....Putting a swimming pool in the back yard is completely different ....than putting that same swimming pool up on top of a 15 story ....building. How close to the Load can the crane park? Or how far you need the LOAD moved. What a crane can lift, even if it a 100 ton crane is based on how far the crane has to reach to pick up the load and how much the crane has to rotate to place the load. The angle the crane boom goes to, etc. Our 15 ton PH crane can lift 30 thousand pounds at 10 feet from the Turning center. And only a 1,000 pounds or less if the boom is fully extended with the Jib on, that is 125 feet away from the turning center of the crane. Distance is critical! They will probably need to see the work site to give a really accurate answer. Wingman
Q:a question about ichabod crane? ten points!?
He was tall, but exceedingly lank, with narrow shoulders, long arms and legs, hands that dangled a mile out of his sleeves, feet that might have served for shovels, and his whole frame most loosely hung together. His head was small, and flat at top, with huge ears, large green glassy eyes, and a long snipe nose, so that it looked like a weather-cock, perched upon his spindle neck, to tell which way the wind blew. A rather tall, slender man with bad posture, and a large nose.
Q:What do lattice boom and hydraulic boom in cranes mean?
LATTICE BOOM: See first link. This is where the boom (the portion used to support the load) is made like a lattice ... i.e. interconnected trusses and girders. The cables for lifting the load are run from the base of the boom to the load over pulleys/gears located at the boom's tip. The boom itself is NOT adjustable in length or in angle. HYDRAULIC BOOM: See second link. This crane uses hydraulics to adjust either the length of the boom, or the angle at which the boom joints intersect. It looks more like a single beam construction, although its probably closer to a tube type design (hydraulics may be inside or outside the arm). The load is raised/lowered by cables operating at the end of the boom ... not necessarily tied back to the bottom of the boom.
Q:Whooping Crane or Whopping Crane?
Whooping Crane is the name for the tallest bird in north america. A whopping crane is just a big-*** crane.
