Nowadays, small cranes are widely used in construction sites, industrial and mining enterprises, docks, electric power, urban construction, and paving bridges. For a long time, small cranes will cause minor problems and glitches for a variety of reasons. Let us talk about how the small crane slows down:
Check the balancing valve at the top of the arm. It may be that the balancing valve has not been cleaned or damaged for a long time.
Check the top arm of the arm to see if there is an internal leakage. At this time, it is recommended that the entire arm be removed for inspection. If it is, then the internal tube needs to be replaced.
Check the hydraulic oil in the hydraulic tank to see if it is not enough or too little. Less hydraulic oil can also cause the arm to slow down.
Under normal circumstances, slow down the small crane is caused by these three reasons, I hope the above content will help you, of course, the maintenance of small cranes is also very important, regular maintenance of small cranes, can greatly extend The life of a small crane.
There are too many places to use small cranes now. Small cranes have played a large role in various industries, but not all industries are used for lifting, and some industries may need to install a hanging basket. Next, let's talk about the requirements for the small crane when it comes to suspending the blue suspension:
The small crane should be able to withstand the force exerted on the support after the basket load, this must be tested well, otherwise there will be a big security risk.
The connection of the small crane's basket must be stable, reliable, and the structure must have sufficient strength.
The basket must have sufficient rigidity and strength, and welds, cracks, rust, loosening of screw rivets, structural damage, etc. cannot occur.
The security guardrail should be solid and strong, and the webbing (not less than 80cm in height and not less than 1000n in bearing capacity) must be installed. Requirements must be met.
Small cranes must have safe and non-slip measures, drainage holes must be provided on the basket to ensure normal use, and there must be safety baffles around the basket and the gap between the baffle and the bottom should not be 0.5 cm.
A wall wheel, guide wheel, or cushioning device is installed on the side of the building or work site.
