JMM series winches are mainly used for mineral, mechanical equipment and other heavy object lifting or travelling. It is widely used in mine shafts and inclined shafts, it is an important mechanism for mineral transport and equipment lifting.
JMW series of winches are mainly used for long-distance traction and large stroke hoisting of various large and extra-large concrete, steel structures, cables etc.
Generally choose the crossover type steel wire rope which has the quality certification so that it will not be twisted and loosened when lifting goods.
Asbestos core and heat-resistant steel wire rope should be chosen when lifting hot or molten metal goods.
The hoisting and luffing mechanism should not be intertwined with the steel wire rope to make it longer. Any other mechanism needs to make the wire rope longer, it must ensure that the joint strength is no less than 90% of the breaking strength of the steel wire rope and should not pass the pulley and cover on the drum.
Features of Wire Rope Slings
Flexibility and resistance to abrasion are the major features of wire rope slings.
Lowest cost per ton of lifting of all slings.
Ideal for heavy loads and rugged conditions.
Wide ranges of possible and terminations
Wire Rope Sling Fabrication
A basic wire rope sling is fabricated by cutting a length of wire rope, unlaying the rope a bit at each end, and weaving the wires back together in the form of a loop. Then, the rope tails are secured by tucking them into a swaging sleeve.
Wire Rope Slings Measurement and Sizes
How to measure and specify wire rope slings? Wire rope diameter and sling length are the key parameters. The length of a wire rope sling refers to the distance from the bearing surface of one eye to the bearing surface of the opposite eye, as shown in the above picture of the wire rope sling. The sizes of wire rope slings are presented in the picture above. These dimensions are considered approximated as they will slightly depending on the individual who fabricates the sling.
Types of Wire Rope Slings
There are 4 types of single-let wire rope slings, ie., the single-part Flemish eye mechanical splice slings, multi-part braided slings, cable laid slings, and Grommet which also can be classified into cable laid and strand laid. Single-part Flemish eye mechanical splice slings Single-part Flemish eye mechanical splice slings are fabricated with a single length of wire rope, typically EIPS grade, and with Flemish mechanical splices.
Multi-part braided slings
Multi-parts branded slings are wire rope slings fabricated by taking a sling long length of aircraft cable or IWRC wire rope and braiding it back and forth along the entire sling design length- including the sling eyes, to form a single, high-capacity sling.
Cable laid slings
Cable-laid slings are fabricated from small-diameter galvanized aircraft cable or IWRC wire rope.
Gromet
A Grommet is a unique type of wire rope sling which forms a continuous loop. There are two basic types of grommets: cable-laid and strand-laid. The cable grommets are like cable-laid slings which are rarely used in modern rigging while the strand-laid grommets are fabricated from one continues length of small diameter galvanized aircraft cable strand or IWRC wire rope strand.
Crane motors overview for you to learn on overhead crane motor, gantry crane motor, hoist crane motors, etc. Types of crane motors, such as, Soft start crane motor, Three-in-one crane, motor, Wound type crane motor are presented for you. Know advantages of each type of crane motor, and get the ideal motor for your crane. Crane motor is a part of gantry crane and overhead crane, which is a kind of equipment for electrical energy into mechanical energy. It is through the electric coil (i.e. stator winding) to produce a rotating magnetic field and its function in the form of rotary torque. The crane motor is divided into DC crane motor and AC crane motor by using different power. The crane motor power system most of the AC crane motor can be synchronous or asynchronous crane motor. The crane motor is mainly composed of stator and rotor, the direction of the force movement in the magnetic field is related to the current direction and the direction of the magnetic induction line. The principle of the crane motor is the effect of the magnetic field on the current force, so that the crane motor rotation.

Overload limiter for material handling equipment is the necessary device to prevent crane accidents caused by dangerous operation of lifting weight exceeding the rated lifting capacity of the material handling equipment. The overload limiter contributes greatly to the safety of lifting equipment and operation staffs.
Components of Overload Limiter
The weight overload limiter mainly consisted of a sensor, computing amplifier, controlling actuator load editor etc. And also the weight overload limiter is equipped with displayer, controller, and alarm for the sake of convenient operation.
Work Principle of Overload Limiter
How does the weight overload limiter work? Generally, during crane operation, the sensor deformation transforms load weight into an electric signal which will be amplified through computing, and then the load weight will be calculated out and displayed. When the loads weight reached 90% of the rated weight, a warning signal will be emitted. And the power source of material handling equipment will be cut off when loads weight exceeds that of the rated to ensure the safe operation of the equipment and operators.
Applications of Overload Limiter
Overload limiter is widely used on cranes and hoists. Generally, the overload limiter takes force from the crane lifting mechanism, sends feedback to the instrument by collecting, calculating, contrasting and judging and finally displays the current weight and indicates the corresponding condition. When the load exceeds the rated weight, the lifting circuit of the Crane Hook will be cut off immediately to keep the crane and operator from dangers.
Features of Overload Limiter
Overload limiter has a wide application range, and is widely used on all kinds of bridge cranes and gantry cranes. Signal sensor inputs while the signal group of relay contactor outputs. The artificial circuit adjusts the built-in potentiometer to set zero and demarcate. How to choose an overload limiter for your application Do not know how to choose the overload limiter for your application? If you want to find the right overload limiter for your equipment, you have to determine the characteristics of the device that you need and establish its dimensions depending on the type.

Customized 20t electric Wire Rope Hoist with 35m lifting height for Philippines customer
On December 10, 2019, my colleague Julia received an email from Glenda, requesting an update on the price of the 20t electric hoist quoted on April 15, 2018. Yes, as early as 2018, we provided customers with a quotation for 20t electric hoist, but the customer had not purchased it. One year passed, the electric hoist price was always changing. The customer’s ongoing project needs this 20t electric hoist, so he asked to update the price.
Client’s company introduction

Customer’s electric hoist requirements
Electric Wire Rope Hoist: CD1 Electric Hoist
Hoist type:electric wire rope hoist Lifting capacity: 20t Lifting height: 35m Voltage: 440V 60Hz 3Phase Control method:Remote Control and pendant control
Update the electric hoist price
Two hours later, Julia updated the quotation to the client. After Christmas, the customer feedbacked the electric hoist price was OK and asked when the delivery can be made. “We need the items end of January 2020.” Glenda said. However, we have a Chinese New Year holiday in January and the factory cannot produce normally. Glenda is very nice and understand our situation very well. We also made a guarantee to accelerate the production of the hoist within 8 days, and strive to deliver the electric hoist before February 5. The customer confirmed the PI and payment method, and immediately arranged the payment.
We completed the hoist production before February 5, and contacted the customer for delivery. However, due to the global outbreak of the COVID-19, Philippines had imposed a nationwide lockdown, and we cannot contact with Glenda. Delivery was temporarily suspended. Fortunately, in March, we finally contacted the him and deliver the 20 tons electric hoist.
Foods industry is the most important industry in each country. We are honored to supply 4 units single girder overhead crane for Philippine food industry. As we know, our customer is one of the Philippines’ largest business conglomerates – San Miguel Pure Foods Company, Inc. (SMPFC).
On the evening of June 25, the night was already very deep, but Jorge was still busy with the new project. He needed to prepare 3 bridge cranes for the new workshop. After viewed our overhead cranes on our website, he sent what he need to us.
“Hi, Can you provide quotation and information for a 3 ton over head crane system for a 16m wide, 36 m length and 7 m height bldg. 2 units also another 10- 12 tons over head crane – 12 m wide and 36 m length 7 meter building. with electric hoist. Looking forward to your quick reply. Thanks. Best Regards Jorge”
However, we are on the Dragon Boat Festival holiday. When we were back to work, we contacted him to confirm more details. Jorge feedbacked his confusion, such as crane voltage, shipment, how many containers will be needed, the major difference in price if they upgrade to 3 tons instead of 2 tons and 12 tons from 10 tons. We answered one by one and put forward our suggestions. In this process, there is a problem that needs special explanation. The motor of the bridge crane can only be three-phase electricity, not single-phase electricity.
After all the problems were resolved, we gave us the final discount price for Manila (CIF Manila). However, Jorge rechecked the width of building for the 12 tons crane, it was 9.25 meters only instead of 12 meters, so we have to change the 12 tons single girder overhead crane solution and redesign it for this. The same work, but it goes well. Jorge also added some protection devices on these overhead cranes, so all the protection devices include: limit switch, overload limit, travel limit, emergency stop, auto braking of all motors, anti-collision device, voltage low protection device, ground fault protection, short circuit, overheating protection and power off protection.
Rechecked the quotation and PI, Jorge arranged payment. Payment method: T/T, 50% prepaid, 50% before shipment.
