Problems solved by technology

Due to the lack of outriggers for hoisting and hoisting, accidents often occur, and the driving speed is faster than crawler cranes; the operation is stable, the lifting capacity is large, and it can be hoisted within a specific range, but the road must be smooth and solid, and the tire pressure must meet the requirements. It is required that the hoisting should not exceed 50CM from the ground. Before the crane is put into production, it must go through a trial weight before it can work. inconvenient

Abstract

The invention discloses a crane weight testing device. A plurality of pin shafts are installed on a hanging block which is fixedly installed at the top end of a hanging beam main body; main steel wireropes are connected to the pin shafts respectively; auxiliary steel wire ropes are installed on the hanging beam main body; tension sensors which are arranged on the outer sides of the correspondingauxiliary steel wire ropes are installed on the hanging beam main body; auxiliary hanging beams are fixedly installed on the two sides of the hanging beam main body; a water pipe is fixedly installedat the bottom of each auxiliary hanging beam and is provided with an electromagnetic valve and an auxiliary water bag; the output end of a processor is electrically connected with the input end of a water pump and the input end of an alarm module; and the output end of the alarm module is electrically connected with the input end of a loudspeaker and the input end of an alarming lamp. The crane weight testing device provided by the invention adopts simple and reasonable structure design, is novel in modeling and practical in function, can well perform weight testing operation on a crane, is good in structure design and liable in balance grasping and can well perform fine adjustment, so that the safety performance is improved while the work difficulty is lowered.

Description

technical field [0001] The invention relates to a weight test device, in particular to a crane test weight device. Background technique [0002] At present, a crane refers to a multi-action hoisting machine that vertically lifts and horizontally transports heavy objects within a certain range. With the rapid development of my country's economy, cranes are widely used in various fields. The working characteristics of lifting equipment are to do Intermittent movement, that is, the corresponding mechanisms for taking materials, moving, unloading and other actions in a working cycle work alternately, and the development and use of cranes in the market are becoming more and more extensive. Due to the lack of outriggers for hoisting and hoisting, accidents often occur, and the driving speed is faster than crawler cranes; the operation is stable, the lifting capacity is large, and it can be hoisted within a specific range, but the road must be smooth and solid, and the tire pressure...
