gantry crane with a truss arm or hydraulic telescopic boom box, can on ordinary roads and assignments; With compact structure, fast transfer, restricted by area small, low cost, etc. All Terrain Crane (All Terrain Crane) originated in Europe in the 1960 s. It adopts specially designed multi-axis all-wheel drive chassis, oil and gas suspension, hydraulic shock, which can realize all-wheel steering, full bridge drive; eot cranes with a truss arm or hydraulic telescopic boom box. Compared the two, all terrain crane has higher adaptability, lifting ability is stronger, higher technology content, cost, of course, also be doubled. In 1890, the British COLES company developed railway scooter as chassis, with vertical steam boiler for cranes, thousands of tons of lifting capacity, rails can rely on. This is the end of the 19th century, the typical structure of mobile cranes. COLES company was once Europe's biggest crane company, founded in London in 1879, the founder of Henry James COLES (1847-1905). Henry at the age of 13 to enter s. orssam machinery factory work, started his own company at the age of 32, to produce 2-10 tons rotary steam crane as the main business. Henry's death in 1905, his eldest son took over the company.

explosion-proof overhead crane

Lifting mechanism includes a motor, brake, reducer, drum and pulley. Motor through reducer, drive roll rotation,explosion-proof overhead crane so the rope around the roll or from roll down to lift heavy objects. Small frame is the bracket and install the hoisting mechanism and operating agencies and other parts of the car chassis, usually welded structures.
Drive mode crane operating agencies can be divided into two categories: one category is focused on the driver, which uses an electric motor to drive the long sides of the Active Wheel drive shaft; another kind were driven wheel that is active on both sides of each with a single motor ,Single Girder Gantry Crane  The more frequent use of a combination of a small bridge crane brakes, gear units and motors into one of the "triple play" drive mode, a large general overhead crane lifting weight for ease of installation and adjustment, often using universal coupling drive .
Crane operation agencies generally only four active and driven wheels, if the weight is large, commonly used methods to increase the wheel from the wheel pressure to reduce. When more than four wheels, a frame must be balanced hinge means that the crane load is evenly distributed on each wheel.

gantry crane rules

1. Gantry crane respond brakes, hooks, ropes and safety devices and other components required check card check and found abnormal, magnet crane should be thoroughly excluded. The operator must confirm the walkway or on unmanned orbit, we can close the main power supply. When there are signs on the lock or power circuit breaker, the person shall be closed original main power removed. 2. Gantry crane working class for the first time when lifting heavy objects (or the maximum load weight), should be lifting height of 0.5 meters from the ground after the heavy down again, check the brake performance, reliable after confirmation then normal operation. Operator in the job, should be required for the following operations to ring the alarm. ① lifting, landing weight; great start when the car driving. ② traveling gantry crane is unclear when the line of sight through to continuous-ringing alarm; ③ traveling crane when the crane near the cross in another. ④ lifting heavy objects near the staff. Operation running under a unified command signal should be. Work in a power outage, the controller should handle all placed in the "zero" position, re-work should be checked before the crane movements are normal. Large cranes, trolley during normal operation, parking brake open anti prohibited; transform large trolley direction of movement, the handle must be placed in the "zero" position,  crane spare partso that after a complete stop functioning institutions in order to reverse to drive. There are two hooks of the crane, when the main and auxiliary hook switch to time and two hooks highly similar, the main and auxiliary hook must work alone, in order. to avoid a collision of two hooks. 3 gantry crane hook after work should be raised to a certain height, carts, trolley stops at the specified location, the controller handles placed in the "zero" position; pull down the protective box switch handle, cut off the power. Routine maintenance. Do shift work.
