Product Specifications

Superlift device

. The two ends of the superlift mast arm are variable cross-section, and the middle is a space truss structure with equal cross-section. The steel pipes are welded, and the top and root of the arm are reinforced with steel plates, which is more conducive to load transmission;

. The length of the superlift mast is 30m;

. Composition: lower arm 12m×1, middle arm 6m×1, upper arm 12m×1.

Hook

. There are 7 types of hooks to choose from, the specific parameters are as follows:

Note: 500t hook can be disassembled into 250t hook, 240t hook can be disassembled into 120t hook,

160t hook can be disassembled into 80t hook. For shield working conditions, 200t single pulley block hook can be selected.

Hook lifting max limit

Working weight

. The working weight is about 415t, including the upper and lower parts, the main engine rear counterweight, the central counterweight, the 24m basic boom and the 500t hook.

Ground pressure

. The average ground pressure with basic arm is 0.175MPa.

Gradeability

. Gradeability with basic arm is 15%.

Torque limiter

. The torque limiter independently developed by Sany is used to form a network with other controllers through the CAN bus to achieve safe and reliable control. The torque limiter can automatically detect the weight of the crane and the angle of the crane arm, and can display its rated load and actual load working radius, hook height, etc.;

. The torque limiter system consists of a large-screen color display, a host, an angle sensor, a tension sensor, and a pressure sensor.

Main and auxiliary hook over-winding prevention device

. Used to prevent the hook from over-lifting. When the lifting hook is lifted to a certain height, the limit switch is activated, the control system automatically cuts off the lifting action of the lifting hook, and the display and buzzer alarm at the same time. At this time, the lifting hook can only be lowered to prevent the over-winding of the lifting hook.

Main and auxiliary hook over-release prevention device
. Used to prevent over-release of the hoisting wire rope. When the wire rope is released to the last three turns, the limit switch is activated, the control system automatically cuts off the rope release action, and the display and buzzer alarm at the same time. At this time, only the rope retraction operation can be performed to prevent the over-release of the lifting hook.
Installation mode/working mode switch
. In the installation mode, some safety devices do not work (such as the lower limit of the auxiliary arm, the angle limit of the moment limiter arm, overload, etc.) to facilitate the installation of the crane;
. In the working mode, all safety devices are effective.
