At MAXTECH's factory, our 3T39M telescopic boom crane, with its excellent performance, accurately and efficiently hoisted various test weights, successfully completing a series of lifting and luffing operations. The stable performance of this crane in key functions is undergoing strict inspection.
At the functional test site of a large - scale factory, the MAXTECH 3T39M crane, with its excellent performance, accurately and efficiently hoisted various test weights, successfully completing a series of lifting and luffing operations. The stable performance of this crane in key functions is undergoing strict inspection.
Understanding the Basic Principles of Crane Operations
Lifting: The Vertical "Journey" of Goods
Lifting is one of the basic operations of a crane. Essentially, it is to lift goods from a lower position to a higher one. The core of this operation lies in the hoisting device. Taking the MAXTECH 3T39M telescopic marone crane as an example, it is equipped with a high - power motor, which is connected to a drum. A high - strength wire rope is wound around the drum, and one end of the wire rope is connected to a hook for hanging goods. When the motor starts, the drum rotates accordingly, and the wire rope can be wound or unwound. When performing a hoisting task, the motor drives the drum to wind the wire rope, thus driving the hook and the goods to rise steadily. To ensure operation safety, an overload protection system is built into the hoisting device. This system monitors the weight of the goods in real - time. Once it detects that the weight of the goods exceeds the rated load of the crane, it will immediately terminate the lifting operation to effectively avoid the occurrence of accidents.
Luffing: Flexibly Adjusting the Angle of the Boom and the Operating Range
Luffing, that is, changing the elevation angle of the crane's boom, is a crucial operation. It enables the ship crane to flexibly adjust the horizontal operating radius and the lifting height of the goods. The luffing mechanism of the MAXTECH 3T39M marine crane adopts an advanced design and is usually driven by hydraulic cylinders. When the hydraulic pump delivers hydraulic oil to the hydraulic cylinders, the pressure generated by the oil causes the hydraulic cylinders to perform telescoping movements. The telescoping of the hydraulic cylinders directly drives the lifting and lowering of the boom. Specifically, when the hydraulic cylinders extend, the boom is pushed upward, the elevation angle increases, the horizontal operating radius decreases, and the lifting height of the goods increases; conversely, when the hydraulic cylinders contract, the boom descends, the elevation angle decreases, the horizontal operating radius increases, and the lifting height of the goods decreases. Luffing operations are usually carried out in coordination with lifting operations. For example, when it is necessary to place the goods at a specific position deviated from the position directly below the crane, the operator first uses the hoisting mechanism to lift the goods to an appropriate height, and then adjusts the angle of the boom through luffing operations to accurately transport the goods to the target position.
The MAXTECH 3T39M Crane in Action: Lifting and Luffing Operation Scenes
In an actual operation scenario, taking the task of installing large - scale equipment on an elevated platform by the MAXTECH 3T39M telescopic boom ship crane as an example. The operator positions the crane, comprehensively inspects and ensures the safety of the operation area environment, and after ensuring that all safety measures are implemented correctly, starts the lifting operation process. The operator activates the hoisting motor, and the drum immediately starts to wind the wire rope, and the hook connected to the goods rises evenly off the ground. With the 3 - ton rated lifting capacity of the MAXTECH 3T39M marine crane, it is more than sufficient to hoist this equipment. During the rising process of the goods, the operator continuously and closely monitors the position of the goods and always pays attention to the various parameter indicators on the crane control panel to ensure that the entire lifting operation is smooth and safe. When the goods rise to a sufficient height, it is time for the luffing operation. The operator controls the device that controls the hydraulic cylinders. As the hydraulic oil is injected into the hydraulic cylinders, the 39 - meter - long boom of the MAXTECH 3T39M crane begins to rise slowly. The operator carefully adjusts the angle of the boom to make the goods exactly above the installation point on the platform. The high precision of the luffing device of the MAXTECH 3T39M crane ensures that the goods can be accurately positioned. After the goods are positioned, the operator then slowly lowers the goods using the hoisting device until the equipment is firmly installed on the platform.
