Tower Crane Parts

Quality inspection center is equipped with mechanical testing spectral analysis, metallography analysis. Precision measurement, universal measuring room, thermal instrumentation, electrical instrumentation. Pressure gauge and other nine laboratories and a series of advanced physical and chemical metrology equipment to ensure product quality. Raw material is Q345B or higher grade from Anshan Steel factory. Changeable for same types of tower crane mast section. Popular types of mast sections as below. L46A1 tower crane mast section/1.6 tower crane mast section. L68B2 tower crane mast section/2m tower crane mast section. L69B2 tower crane mast section.

The telescopic cage use for the telescoping of the mast sections. Below types of telescopic cage provide by SYM. 1. L46A1 tower crane telescoping cage/1.6m tower crane telescoping cage. 2. L68B1 tower crane telescoping cage/2m tower crane telescoping cage. 3. L68B2 tower crane telescoping cage/2m tower crane telescoping cage. 4. L69B2 tower crane telescoping cage/2m tower crane telescoping cage. For 2m tower crane telescoping cage, to fit for loading container, SYM designed detachable one, to save shipping cost.

Beyond its free standing height, the tower crane need connected with building by anchorage frame and tie bar to reach more height. Below anchorage frame or tie-in available: 1. 6m tower crane anchorage frame/1.6m tie-in, 2m tower crane anchorage frame/2m tie-in/2m collar, 2. 5m anchorage frame, 4m anchorage frame. Designing tie bar of anchorage frame base on job site conditions is a service in free from SYM tower crane.

Raw material is Q345B or higher grade from Anshan Steel factory. Fixing angle models as below. 1. 1.6m tower crane fixing angle/φ55 pin tower crane fixing angle. 2. 2m tower crane fixing angle/φ65 pin tower crane fixing angle. 3. reusable tower crane fixing angle for 1.6m and 2m.

The main components use the Schneider brand, including frequency converters. The control cabinet has two kinds of shells: stainless steel and iron plate. The overall installation of the plate, the direct riveting of the spare cap, the components are more firmly fixed. Standardize the wiring in the cabinet to reduce the occurrence of wiring faults. It is connected with external wiring by connectors, which is convenient for disassembly and assembly and reduces the occurrence of failures. The cabinet door is affixed with company logos and warning and reminder marks.

The slewing reducer and trolley reducer enable absolutely jolt- and jerk-free slewing at micro-speeds. Wind and load influences are all detected. Integrated anti-sway damping compensates for crane vibration and load swing. The integrated electrical wind release can be activated directly at the base of the tower. The crane operator now has a choice between rotational-speed control and torque control.

The electrical control system has compact structure, reasonable layout, reliable quality and low maintenance cost etc. All electrical parts are from famous supplier at home and abroad. We can match the components of Electric Control Panel according to customers' specially requirement. The panel strictly follows international universal standard, thus it can replace customers' same panel. These Panels can control 450-16000 KNM tower crane. We supply original Altivar 71 and 903 inverter for tower crane as well as other tower crane spare parts with good quality, competitive price, short delivery and professional service.

The brake disc is composed of steel plate, adhesive heat insulation layer and friction block. The anemometer is generally set with alarm wind speed, if the current wind speed reaches the alarm wind speed, it will send sound and light to alarm; If the current wind speed reaches the control wind speed, the instrument will send a control signal to provide corresponding control processing when the sound and light alarm is issued. Load moment indicaor, through the display screen, the tower crane lifting height, height, load capacity, torque and wind speed are visually displayed and protected, and sound and light prompts are provided when overload or over torque is approaching.

Multiturn encoder: 4~20mA linear output and RS485 digital output，More flexible multifunctional intelligent absolute encoder，Measuring angle, length and speed This product combined the controller and thyristor module, the connection of the users is simple and easy. This is to prevent the damage of the controller and thyristor module caused by mis-wiring of the customer. Joystick widely apply for various products and operating modes. The electrical control system has been optimized on the base of technology. So it has many advantages, such as compact structure, reasonable layout, reliable quality and low maintenance cost etc. All electrical parts( contactor, relay, terminal and so on) are from famous supplier at local or abroad.

The Motors(hoisting motor, slewing motor, trolley motor and traveling motor) are designed and manufactured on the basis of the overseas mature technologies. It is constituted with torque three-phase asynchronous motor, built-in planetary reducer, winding drum, tack and other components. The mechanism can get low, medium and high speed by voltage control and eddy current brake. The motor is equipped with an electromagnetic disk brake with features of smooth start and braking, safe & reliable braking and accurate positioning.
