1. Brief Introduction - Condensing Unit 1) Utilizes the world-renowned Bitzer ECOLINE series semi-hermetic piston compressor, offering high reliability. 2) Multiple compressors are parallel connected to provide larger capacity sharing the same discharge pipe, suction pipe, condenser, liquid receiver, etc. 3) Compact design for easy installation and small installation size. 4) Multi-stage energy adjustments according to cooling capacity to save operation cost. 5) Can meet medium and low temperature requirements. 6) Other power supply not mentioned in the specification is optional, such as 220/440/460V-3Phase-60Hz. 7) Application: Meat, vegetable, fruit cold storage, food preparation workshop, chemical cold room, medicine cold room, freezer tunnel, blast freezer, walk-in freezer, supermarket food display cabinets, fresh keeping, etc. 2. Characteristics: 2.1 Variety of Options Piston type 2 compressors parallel unit Piston type 3 compressors parallel unit Piston type 4 compressors parallel unit Adopted to multiple refrigerants R404a, R507, R407C, R22. 2.2 Stable & Reliable The units are equipped with world-famous brand high-quality compressors and components, following the latest design, the perfect combination provides a safe and reliable system. The unit comes standard with a controller that can effectively avoid turning on/off the motor frequently as well as safety protection modules including the following: Phase loss protector, Inverted sequence, Overvoltage protector, Undervoltage protector, Oil pressure, High pressure, Low pressure, Motor overload. 2.3 High Efficiency & Energy Saving Because of a huge demand difference between seasons for refrigerating capacity, the unit must have a high level control for capacity, so that the unit can keep running under high efficiency mode. The average parallel unit efficiency, according to different refrigeration system is 30% higher than single compressor unit. Using multiple compressor parallel units can provide a multiple energy level control, the refrigeration output can be dynamically allocated more smoothly according to actual situation. With high efficiency oil separator, only a small amount of lubricating oil enters the system, this largely brings up the heat exchanging efficiency. 2.4 Compact & Nimble Components such as compressor, reservoir, gas-liquid separator, oil separator, electrical control equipment, etc are all centralized, making sure every inch of the space is fully used. The unit has a compact structure, the space saved during assembly can provide more space for commercial use, benefiting the end user with extra profit. 3.

Tower Crane Cabin

Tower Crane cabin is the control center of the crane and is attached to the slewing unit. In order to get to the tower crane cab, the operator must climb a series of ladders within the mast.

The movement of the tower crane is controlled from the operator's cabin. Within the tower crane cabin, you'll find the operator's chair with joystick controller, electronic monitoring devices, and communication systems. Many cabins come with climate control to ensure a comfortable work environment. The Operator Cabin for Tower Crane is part of the slewing assembly.


A cabin for a tower crane is a small enclosed space located at the top of the tower crane Mast Section or tower crane jib. It is where the crane operator sits and controls the crane's movements and operations. The tower crane cabin is typically made of steel or aluminum and is designed to provide a safe and comfortable working environment for the operator. It is equipped with controls, instruments, and communication systems that allow the operator to maneuver the crane, lift and lower loads, and communicate with other personnel on the construction site. The cabin is often equipped with heating and air conditioning systems to ensure the operator's comfort in various weather conditions. Safety features such as guardrails, harness attachment points, and emergency controls are also included in the cabin design to protect the operator in case of accidents or emergencies.
