Model TC7550 Tower Crane is designed and manufactured by Shandong Mingwei Hoisting Equipment Co.,Ltd. According to the Chinese standard of "Classification of Tower Crane".
The TC7550 tower crane is a self-erecting multi-purpose machine with a horizontal jib, a trolleying mechanism and an upper slewing mechanism. Its characteristics are:
1. The performance parameters and technical indicator of the crane are at a leading level in China. The maximum working radius is 75m and the maximum hoisting height is 275m.
2. The outline of the crane is international fashion model and very perfect, enjoyed by the users.
3. The crane has many working mode, it is used in different condition. Such as:outrigger stationary, undercarriage stationary, anchored to the building and mobile, so that it is applied in different construction projects. The hoisting height of the outrigger stationary or the undercarriage stationary is 73m. The hoisting height of the crane anchored to the building reaches to 275m based on the outrigger stationary or the undercarriage stationary, added the tower sections and anchored devices.
4. It has high working speed and good regulated speed performance. The technique of the step-less speed regulated and frequency altering is used in the hoisting mechanism, the trolleying mechanism and the slewing mechanism, so the crane works more smoothly and reliably.
5. The main electric components are used world-renowned products, which service life is 3~4 times longer than China-made counterparts with less failure, simple maintenance and reliable working.
6. All equipped safety devices are mechanical-electrical integrated products, and adapt to all badly conditions to ensure the crane working reliably.
7. The design of the crane is based on the actual situations in China and on the safe-reliable operation principles. Greatly absorb and adopt the well-established and reliable advanced technology to enhance its overall technical level at the same time in the world.Well-established advanced technology adopted as following:
1) Electric components are made by specialty electronics factories that have brought in the technology of TE company, France;
2) Weight limiter, height limiter, radius limiter, slewing limiter, slewing brake, traction brake and similar safety guards are China-made based on the brought in technology;
3) Rope-break-proof device(carriage slip-proof) and axle-break-proof device are used on the carriage.
4) Rope pay-off system for hoisting mechanism;
5)Traction rope-tensioning system;
6) Large-radius hoisting jib suspended by double rigid pull rods, featuring good jib rigidity, light jib weight, small jib cross-section, small wind resistance and nice-looking appearance and several jib lengths, it is satisfied different construction needs.
7)Ou-hung operator cabin, featuring excellent field of view, spacious interior, it is satisfactory working environment to the operator.
8)Advanced inter-active control console, the operator handles the mechanisms easy and services simply.
8. The design of the crane completely conforms to or is superior to the relevant national standards.
The crane is suitable for use in such large-sized construction projects as high-rise or super high-rise buildings, bridge and water conservancy projects, large-span industrial buildings, large gymnasiums, and high chimneys and silos constructed with slip form.
