What does YOM mean and which years do you supply?

YOM means Year of Manufacture. Our current used tower crane and construction hoist stock mainly covers YOM 2018 to 2023, and each listing states the YOM shown on the machine nameplate.

How is a used tower crane inspected before export?

Our quality inspection team checks mast sections and structural welds for cracks or deformation, slewing bearing clearance, hoisting, trolley and slewing mechanisms, wire ropes, brakes, safety limiters and the electrical system. Photos and videos of the actual unit are shared with the buyer before shipment.

How are used tower cranes and construction hoists shipped overseas?

Machines are disassembled into mast sections, jib, counter-jib, cab and mechanisms, then marked and loaded into containers, flat racks or bulk vessels depending on size. Our own logistics team handles land transport and professional loading and unloading.

Which export documents are provided?

Standard export documents include the commercial invoice, packing list, bill of lading and certificate of origin. Additional documents required by the destination country can be arranged on request.

Can I inspect the machine before purchase?

Yes. Buyers can visit our 30+ acre warehouse base in Huai'an, Jiangsu, China, appoint a third-party inspector, or request a live video inspection of the exact unit.

Product Selling Points

MC320K12 is one of the main models of the series products. The series products have introduced the design concept and control technology of automotive cranes for the first time in the industry, with "high safety" as the core, and a series of products with important features of intelligence, strong performance, excellent quality, excellent efficiency, and precise modules.

Product Introduction & Key Features

The industry's first application of high-strength cold-formed steel, with lighter arm frames and better lifting performance than other manufacturers in the same industry, with a leading level of lightweight in the industry.

The entire machine is equipped with 8.8-10.9 grade Dacromet high-strength bolts, which have higher strength, stronger rust prevention ability, and longer service life.

The structural components adopt powder electrostatic spraying technology, with automotive grade coating level, and will not fade for 2 years and rust for 5 years.

The entire platform is made of aluminum alloy material, which will never rust.

For the first time, the design concept of the driver's cab in the automotive field has been introduced into the tower crane industry, using electrophoretic treatment technology to achieve a 10-year rust free driver's cab.

The external unit of the air conditioner is built-in and installed and transported as a whole to avoid damage to the external unit and reduce the risk of outdoor operation during installation and maintenance.

Modular lifting technology for the entire machine significantly improves installation and dismantling efficiency by 20-30%.

The full frequency conversion control method achieves flexible operation of various mechanisms, without any impact, leading in green, efficient, and intelligent levels.

Industry leading load and speed control technology and worm speed control technology meet the needs of prefabricated buildings.

For accessories, relying on national quality inspection institutions, achieving three-level coverage of product testing scope, and achieving batch professional testing of key components such as raw materials, high-strength bolts, and sales shafts.

All supporting components for the entire machine are from the top two manufacturers in the industry.
