During the operation of the manual lever hoist, attention must be paid to several technical points. The first is to ensure that the hook and the fixture of the manual lever hoist are reliably fixed, and the chain hook is reliably linked to the suspended load. . During the lifting of the weight, the knob is turned to the “up” position card, and then the handle is reciprocated, and the weight rises steadily as the handle reciprocates.
Secondly, in the process of using a manual lever hoist to slowly lower the weight, the worker should first turn the knob to the “down” position on the indicator board, and then reciprocate the handle, and the heavy object will move along with the handle. A steady decline. In addition, if you need to adjust the position of the hook, it is recommended to turn the knob to the “0” on the indicator when it is empty, and then turn the handwheel to adjust the upper and lower positions of the chain hook.
From the point of view of daily use, as a user, in order to ensure the effective operation of the operation, first of all, we should pay attention to select the appropriate size of the manual lever hoist for use, and strictly prohibit overloading. Moreover, before each operation, it is necessary to carry out safety inspections, and at the same time, the opponent's hoist hoist is subjected to no-load test, and the position of the lower hook is properly adjusted according to actual requirements.
In addition, after use, it is necessary to strengthen the maintenance of the manual lever hoist. The specific contents mainly include: 1. After use, the gourd should be cleaned up, painted with rust-proof grease, and stored in a dry place. 2. Maintenance and overhaul should be performed by those who are familiar with the hoist mechanism, and they must not be disassembled and installed at will. The installation of the gear part should be done according to the drawing.
In addition to the above points, in the installation work, the clockwise direction should be used to turn the handwheel so that the ratchet wheel and the friction plate of the manual lever hoist are pressed against the brake air seat and the groove nut is installed. Remember, after the manual lever hoist is cleaned and inspected for maintenance, an empty and heavy load test should be performed to confirm that the work is normal, automatic and reliable before it can be used normally.
