The quay side container crane, also known as a ship-to-shore crane, is an essential piece of equipment in port operations. Its primary purpose is to efficiently load and unload containers from ships at the quayside. This massive crane plays a pivotal role in the efficient transfer of goods between ships and land, facilitating international trade and contributing to global supply chains.
Now, let's dive deeper into the structural characteristics that make the quay side container crane an impressive feat of engineering. At its core, this crane is built for strength and stability, as it needs to handle heavy loads and withstand the challenges of working near the sea. Its structure typically consists of a tall steel tower, mounted on a sturdy foundation. The tower supports a horizontal boom known as a jib, which extends outwards over the water. This jib is capable of traversing back and forth along the length of the quay, enabling the crane to reach containers positioned at different locations on the ship.
To lift and lower containers, the quay side container crane is equipped with multiple hoisting mechanisms. These mechanisms typically include powerful winches with wire ropes. The ropes are attached to the lifting hooks or spreader beams, allowing for controlled vertical movement of the containers. The crane's lifting capacity is carefully engineered to handle the weight of fully loaded containers, ensuring safe and efficient operations.
Safety is paramount in the operation of a quay side container crane. These cranes are equipped with a multitude of safety devices and protocols. They often feature anti-sway systems to minimize any swaying or pendulum movement of the load. Additionally, limit switches and load sensors are in place to prevent overloading, ensuring that the crane operates within its safe working limits. This focus on safety ensures the protection of both personnel and cargo during lifting operations.

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.
Other Brands
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.
