A deck crane, also known as a boat crane, plays a crucial role in maritime operations. Its unique structural characteristics make it an indispensable tool for various tasks onboard ships.
The structural characteristics of a deck crane are designed specifically for marine environments. Unlike typical cranes such as gantry cranes or overhead cranes, a deck crane is mounted on the ship's deck, providing stability and flexibility during operations. Its pivotal feature is the slew ring, a circular bearing that allows the crane to rotate 360 degrees, facilitating precise load handling and maneuverability. Additionally, deck cranes are equipped with hydraulic or electric systems to control the lifting operations, ensuring smooth and efficient cargo transfer.
The significance of a deck crane in maritime operations cannot be overstated. It plays a key role in loading and unloading cargo, such as containers, machinery, and provisions, onto and off the ship. This increases the efficiency of port operations and reduces turnaround time, enabling ships to adhere to tight schedules. Moreover, deck cranes are instrumental in emergency situations, such as search and rescue operations or salvaging sunken ships, providing crucial lifting capabilities to retrieve or relocate items underwater.
Compared to traditional cranes used on land, deck cranes exhibit several notable differences in terms of their applicability and functionality. Firstly, deck cranes are specifically designed to withstand harsh marine environments, including saltwater corrosion and extreme weather conditions. The materials used in their construction are highly durable and resistant to deterioration, ensuring reliable performance even in challenging marine settings. Secondly, deck cranes are compact in size and can be maneuvered within tight spaces onboard a ship, making them suitable for limited working areas. Lastly, deck cranes are equipped with safety features and mechanisms to ensure secure cargo handling, as maritime operations demand utmost care and attention to avoid accidents or damage to goods.

Our Material
1. The raw material
procurement process is strict and
has been inspected by quality inspectors.
2. The materials used are all steel products from
major steel mills, and the quality is
guaranteed.
3. Strictly code into inventory.
1. Cut corners, originally used 8mm steel
plate,but used 6mm for customers.
2. As shown in the picture, old equipment is often
used for refurbishment.
3. Procurement of non-standard steel from small
manufacturers, product quality is unstable.

Our Motor
1. Motor reducer and brake
are three-in-one
structure
2. Low noise, stable operation and low maintenance
cost.
3. The built-in anti-drop chain can prevent
the bolts from being loosened, and avoid the
harm to the human body caused by the accidental fall
of the motor.
1.Old-style motors: It is noisy, easy to wear, short
service life, and high maintenance cost.
2. The price is low and the quality is very poor.
Other Brands
Our Wheels
All wheels are heat-treated and modulated, and the surface is coated with anti-rust oil to increase the aesthetics.
1. Do not use splash fire modulation, easy to
rust.
2. Poor bearing capacity and short service life.
3. Low price.

our controller
our inverters make the crane run more stable and safe, and make the maintenance of the more intelligent and easy.
the self-adjusting function of inverter allows motor to self-adjust its power output according to the load of the hoisted object at any time, thereby saving the factory costs.
the control method of the ordinary contactor allows the crane to reach the maximum power after it is started, which not only causes the whole structure of the crane to shake to a certain degree at the moment of starting, but also slowly loses the service life of the motor.
