1. Classification of monorail cranes
According to different power, monorail cranes are mainly divided into three categories: explosion-proof diesel engine monorail trolley hoist for sale (DC series), explosion-proof special battery power (DX series) and explosion-proof lithium battery power (DL series).
1.1 Explosion-proof diesel engine monorail crane is customarily called “diesel truck”.
Its main advantages: strong power, large traction, and strong climbing ability (can climb 25-degree slopes). The maximum load capacity at a 25-degree slope is 32 tons.
At present, the diesel engine monorail crane can achieve 12 drives; the traction force of each drive is 25KN, and the maximum traction force reaches 300KN.
Its main disadvantages are: the exhaust gas emitted by the diesel engine causes pollution to the narrow tunnel space, noise pollution, and complicated maintenance.
1.2 The explosion-proof special battery monorail crane is customarily called a “tram”. (The battery is a lead-acid battery)
1.2.1 Its main advantages: It is more environmentally friendly and energy-saving than diesel locomotives, has no exhaust gas pollution, and is easy to maintain.
1.2.2 Its main disadvantages:
a. The traction and climbing ability are not as good as those of diesel engine monorail crane.
b. The battery is charged in a special chamber and the charging time is long.
c. Lead-acid liquid may cause pollution to the environment.
d. The maximum applicable slope is 15 degrees. The maximum load capacity at a 15-degree slope is 23 tons.
e. The current battery monorail crane can only achieve 6 drives; the traction force of each drive is 20KN, and the maximum traction force is 120KN.
Our company’s newly developed battery monorail hoist and trolley price can achieve 8-wheel drive and the maximum traction force can reach 208KN.
1.3 Lithium battery (lithium iron phosphate) powered sevencrane monorail hoist price. (Lithium battery is lithium iron phosphate battery)
Its main advantages:
a. Environmental protection and energy saving, no waste gas pollution and chemical liquid pollution.
b. It can achieve 12-wheel drive and the traction force can reach 240 KN. The operating slope can reach 25 degrees.
c. Charging is convenient and can be charged on standby.
2. Structural characteristics of monorail crane
2.1 The basic configuration of a monorail crane consists of four parts: driver’s cab, drive unit, electro-hydraulic control vehicle, and power unit system.
2.2 The running track adopts German industrial DIN20593 standard I140E or I140V I-beam steel, which is flexibly fixed on the top of the tunnel by a chain. The locomotive’s running load-bearing wheels are stuck on both sides of the I-beam. There is no derailment or falling off the track, and the brakes stop It is realized by the brake spring clamping the track web. The action mode is failure braking, and the operation is safe and reliable.
3.Use of monorail crane
3.1 Equipped with 5T/8T/16T lifting beams, it can complete the transportation of support materials, belts, cables and small equipment; equipped with corresponding containers, it can complete the transportation of building materials and scattered spare parts; equipped with manned vehicles, it can complete the transportation of underground personnel; each section The vehicle can seat 10 people and can transport 30-50 people at a time; it is equipped with a special lifting beam to complete the transportation and transfer of large equipment such as hydraulic supports.
3.2 The monorail crane is an underground auxiliary transportation equipment system with low investment, easy maintenance, multi-function and high efficiency.
