Jxf/jxl Trolley Mechanism

Electric overhead travelling (eot) crane mainly includes three major operating mechanisms: a lifting operating mechanism, a trolley operating mechanism, and a trolley operating mechanism. The hoisting mechanism is mainly composed of electric hoist, wire rope, pulley, hook or spreader. The metal structure of the electric single-girder bridge crane is mainly composed of a main beam and an end beam. The main beam structure is mostly a combined section of I-beam and steel plate, which is composed of a cover plate, a web and an I-beam, and there are longitudinal and short reinforcing ribs in the box. Its safety and reliability directly affect the operating quality and working ability of the crane.

Double beam gantry crane is a variant of gantry crane. There are double-beam gantry cranes, as well as single-beam gantry cranes. It is mainly used for loading and unloading of outdoor cargo yard, storage yard cargo and bulk cargo. Gantry cranes have the characteristics of high site utilization, large operating range, wide adaptability, and strong versatility. They have been widely used in port cargo yards. Its metal structure resembles a door-shaped frame. Two feet are installed under the main beam, which can directly walk on the ground track. The main beam can have outriggers at both ends. Gantry cranes are bridge-type cranes where the bridge is supported on the ground track by the legs on both sides. It is structurally composed of a mast, a trolley operating mechanism, a crane trolley and electrical parts. Some gantry cranes have outriggers on one side, and the other side is supported by a factory or trestle, which is called a semi-gantry crane. The gantry crane consists of the upper bridge (including the main beam and the end beam), the outriggers, and the lower beam. In order to expand the working range of the crane, the main beam can extend beyond the legs to one or both sides to form a cantilever. A crane trolley with a boom can also be used to expand the crane's operating range by tilting and rotating the boom.

High Torque Brusless Hub Motor : which is located within the rear wheel and drives magnetically with no brushes or gears to wear out or create noise. They are proven technology that operate with very high efficiency, has no wearing parts like gear and axle. The risk of mechanical failure in these parts are eliminited. Pivoting Rear Drive Wheel With Lock Spring : makes it one of, if not the easiest handling electric trolley on the market today. It provides exceptional handling, stability and manoeuvrability. Allows the buggy to be controlled with the very lightest of touches. Safe Start : prevents the motor from driving the buggy until the "start" button pressed, if the Freewalker is stationary when the power is switched on nothing will happen until the user presses the "start" button. Auto Disctance Control -TIMER : Press the "timer" button, your cart will proceed at the selected speed for the distance (15/30/45M) you have selected. Cruise Control : maintains the speed of the trolley irrespective of terrain, so you do not need to continually adjust the speed control dial of the buggy when going up or down hills to hold a constant speed. Descent Control :Setting the speed roller to minimum (i.e. fully towards you) can activate descent control. If the set speed of the Freewalker is too fast to negotiate a hill, engaging Descent control will then limit the speed of the trolley and allow for more control. Power Brake : is in addition to the descent control. The electronic brake can be utilized in the following ways; If the hill is very steep and requires additional braking, the brake button can be pressed once and again repeatedly in order to control the speed of the descent - or alternatively the brake button can simply be pressed on and the trolley will make its descent at a slow crawl. LOW BATTERY PROTECTION : protects the battery from damage as a result of being excessively discharged. The effect of this is that when the battery capacity drops 10% of the capacity left, the LED beside the "start" button will flash red and warn you to recharge the battery soon. Weight: 20.5 kg Buggy: 11.5kg, Battery: 9kg Dimensions: (mm) Unfolded: 105 (L) x 64 (W) X 100(H) Folded : 83 (L) x 64/34 (W) X 30 (H) Width (with/without wheels)
