15 ton electric hoist tests



15 ton electric hoist tests

How to test the electric hoist?

Electric hoist testing is always required after installation. In today’s video, the 15 ton electric hoist has gone through various tests.



After inspection and preparation, the electric hoist operation test can proceed. The running test of electric hoist can be divided into the following three steps: no-load test, static load test, and movement test.



Electric hoist no-load tests

Electric hoist no-load test are mainly divided into the three parts, the electric hoist travelling test, crane travel test, and no-load hook test.



Electric hoist travel test

• Start the electric hoist of electric hoist

• Make the electric hoist run back and forth along the rail more than 3 times

• Test limit switch to make sure is sensitive and reliable.

• The driven wheels must touch rail all the time, the space between positive wheel and rail should be not more than 1mm.



Crane travel test

• Make the electric hoist run back and forth along the rail more than 3 times. Each time running distance is 3m at least.

• Wheels of the electric hoist must not stuck rail.



No-load hook test

• Lift the empty hook up and down more than 3times.

• Examine brake and lifting limiter.

• All traveling and lifting mechanism must work stable, no vibration and shock



Electric hoist static load tests

• Before Static load testing, the no-load test must be qualified.

• Set crane on one end of rail. Trolley/hoist lifts the rated capacity and travel along the crane girder back and forth.

• Unload the loads and set the trolley to one end of the crane girder.

• Hanging a plumb in middle of crane girder to examine the original bending degree. Operating trolley/hoist come to middle of girder, lifting loads 1.25times of rated capacity, up to 100mm, and keep this condition 10min on both sides of girder.

• Then examine the bending degree again.

• Then unload the capacity, to check if girder has any permanent change. This testing should do 3times.

• Then examine the final bending degree which should be bigger than 0.8L/1000.

• Place trolley/hoist stop in middle, lifting rated capacity to test girder’s resilience downwarping, which should not be more than L/700. For single girder electric hoist, the resilience downwarping should be not more than L/600.



Movement load tests

• Lift loads of 0.5 time, 0.7 time, 1 time and 1.1 times of rated capacity of the electric hoist.

• Make trolley/hoist travel several times.

• If no problem is observed, start crane traveling mechanism and run the electric hoist several times.

• Lifting mechanism must be operated 10-15min, traveling mechanism must work 20min or 10times.

• Ensure the brake is workable, reducer has no noise, no vibration, and temperature is normal, no oil leaking;

• Make sure the lubricating system is fine.

• Make sure all limiters and safety device are reliable.

• And electrical box is fine, temperature is normal, no noise, no vibration, cable/line connecting is not burnt.

How to operate EOT Crane?

Europe Standard EOT crane operation method

HD electric overhead crane
Modern society, the demand of Europe Standard EOT crane is more and more, especially in the current rapid development of science and technology, business is booming, the effect of crane is more prominent.But European crane as a kind of heavy machinery,should pay attention to safety, so what are the main place to pay attention ?See below.
Want to guarantee the safety of Europe Standard EOT crane, it is important to ensure that the crane’s performance is good, especially the crane use time is too long, before each use, all must check of various components in detail.Especially the jib crane, see whether its scale is in normal state,Whether the firm ,must not have the overload.And, then, is to check the oil, if found that there is lack of or no, to complement immediately, be sure to ensure the normal operation of mechanical energy.
NLH & BMHN electric hoist gantry crane
At the time of EOT crane operation,be careful not to hurt others.Because the crane is very heavy, action is not so convenience, as long as there is a little deviation is easy to hurt people around .When we were in the use of crane do not pass through man’s head, this may be the cause of objects fall off and cause casualties.Also can’t stand people below the crane arm, sometimes someone standing underneath the machine arm, slightly do not pay attention to, is likely to hit him.
Must follow the rules when operate European EOT crane , sometimes with interphone,sometimes is a command signal, can only be better listen to the command.Commanders in the outside can see the scene of the actual situation,operators and sometimes can not see as well.

What is bridge crane installation?



What is bridge crane installation?





The installation of bridge crane,Check deformation and damage for the metal structures and mechanical electrical equipment in the transport.And repair processes,and then assembled on the ground, and then to integral lifting.The main lifting equipment of this method is a hoist lifting mast and the ground winch.Do a rotation Angle for the bridge crane whole,with stable rope continue to ascend beyond altitude,Determine the direction,according to the determine location placed in orbit.



At the top of the mast must use a certain number of cable wind rope fixed,Cable wind rope strength and fixed method shall be calculated and tested.Set the cable wind rope shall not interfere bridge in rotation in the space.At the same time must be measured before installation and pick up from the centerline of the orbit to the lateral wall.Otherwise the bridge in space rotation will be affected.



This method of installation for lifting equipment capacity is big, but as a result of bridge crane assembly on the ground, so much less high, labor intensity is small, the installation cycle is short.



But some bridge crane due to plant pillars, roof and walls, such as the limitations of space position,cannot be used integral hoisting installation method , only the subsection hoisting method.Division hoisting method is to dispose of bridge beam connection apart, put each of the two main girder crane to orbit, put the car lift to higher than the height of girder position.Then put two main girder, together, will end beam connection, finally put the car into the car.This way of lifting altitude is difficult.

Material Handling Roof Hoist Systems

Material Handling Roof Hoist Systems
ND Model Electric Hoist
CD Model Electric Hoist
Wire rope electric hoist system is a lifting equipment which widely used and necessary in Industry, it can be installed on single girder overhead crane, single girder gantry crane, jib crane and I-beam. According to different design principles and using environments, Electric hoist also divide into  single speed (CD electric hoist), double speed(MD Electric hoist), square box(HC electric hoist) and curve traveling hoist(CDW electric hoist), anti-explosion type, metallurgical type, Europe type and Low headroom type, etc. What’s more, the electric hoist also can be designed to pendent control and wireless remote control.The low headroom wire rope electric hoist is improved from CD & MD type electric hoist, the working condition same as CD & MD type wire rope electric hoist, but it increases more clean lifting space, you can save more construction cost of workshop.
