CD, MD, HC various types of electric hoists are suitable for different working conditions.
Domestic mature product, simple structure, strong stability, high safety factor, long mechanical life, easy maintenance, and high cost performance.
Wire rope electric hoist is a kind of light and small lifting equipment, which can be used alone or in combination with overhead crane, gantry crane and jib crane, etc. It is widely used in railways, docks, industrial and mining enterprises, warehouses and other places.
Except the HC hoist, which meets the requirements of larger tonnage lifting operations.
There are two typical types:
The CD hoist is single-speed hoisting, 8m/min, which can meet the general requirements;
The MD hoist is double-speed, 8m/min&0.8m/min, which can meet the requirements of precision loading and unloading, sand box clamping, and machine tool installation and maintenance;
To guarantee the quality of our equipment, each electric wire rope hoist have been complete inspected and tested to avoid any damages during the working. We consider it as the responsibility of electric wire rope hoist manufacturers to ensure the safety of our equipment as same as your operator.
ZD Conical Rotor Motor/ ZDS Conical Rotor Motor. The ZD 0.8～13KW hoisting motor is a cone-rotor three-phase asynchronous brake motor. The standard motor insulation class is Class B(can reach Class F and H based on the working requirements). The protection grade is IP44/IP54. It has the characteristics of good heat dissipation, long service life, safety and reliability, and can be suitable for long-time work in high-intensity work situations. When the motor is at ±10% of the rated voltage, the electric hoist will start and brake normally under the rated load state.
It is the core component of the electric hoist. It adopts a three-stage helical gear transmission mechanism. The gears and gear shafts are made of heat-treated alloy steel, and the bearings are all rolling bearings. The box body and lid are made of high-quality cast iron (grey iron HT200 with good vibration resistance), tightly assembled and well sealed.
It is mainly composed of shell, drum, intermediate shaft device, rope guide device and limit guide rod device. The shell is rolled by steel plate, and the sleeve is made of high-quality cast iron or steel pipe. A rope guide is installed on the reel to make the wire ropes orderly arranged without disorderly rope. In addition, the left and right movement of the rope guide card plate pushes the guide rod device to move, so as to realize the limit stop protection of the electric hoist ascending and descending. The steel wire rope is selected in GB/T8918 important purpose steel wire rope, and the safety factor is greater than 4.5 times.
It conforms to the GB/T1005.1～5-98 standard. Forged with high-strength and high-quality carbon steel, such as DG20, with a safety factor > 5. 0.5-5t uses a single pulley hook device, 10t and larger tonnage adopts double pulley type hook device. The hook surface is smooth and no defects such as cracks, folds, and overburn; there are no internal defects such as cracks, white spots, and other inclusions that affect the safety of use. The hook is equipped with an anti-decoupling safety buckle to prevent the wire rope from decoupling and a 360° free rotation facility. Ensure the safety and reliability of the hook during use.
The hoist trolley is composed of a traversing motor, reducer, wall plate, driven an driving wheels, flat nuts, bolts, and adjustment pads. If the lifting height exceeds 9m, 2 trolleys (one active and one driven) are required; for 10t and above, two active trolleys are required. The motor adopts ZDY series cone rotor brake motor or soft start motor.
Fire off limit switch, heavy hammer limit switch, overload limiter, pressure loss and phase error protection, etc.
