WHAT’S NEW?
NEW DEMAG CHAIN HOIST FEATURES
BALANCER FUNCTION Lifting equipment manufacturer Demag has launched a new range of electric chain hoists. The DCBS models feature a compact design and a smart control system, making material handling and assembly processes simpler and safer. The DCBS is a variable-speed chain hoist based on the company’s proven DCS range and incorporates the Demag D-Grip Servo control handle. Models are available with SWLs of 125kg or 160 kg.
The DCBS chain hoist benefits from an integrated balancer function, which has been adopted from the Demag D-BE electric balancer. It enables loads to be guided without the need to actuate the controller. The operator simply moves the load to the desired height with minimum effort and can position it much more precisely, using both hands.
Depending upon choice of operator selected or automatic control mode, the DCBS unit switches between ‘grip control’ and ‘load control’ operating modes, with high-performance sensors facilitating intuitive load control. Manual force exerted by the operator is detected in the grip control system by a pressure sensor and is used to control the lifting motion. This eliminates the need for the operator to press any buttons to control the hoist.
An integrated load sensor detects the weight of a load and possible weight fluctuations to determine the desired direction of movement and speed from these values in load control mode. This
COMPASS GROUP CLOSES MORE THAN HALF OF ITS
BUSINESSES In the latest trading update by Compass Group, the multinational food and support services company has seen 55% of its businesses closed due to country lockdowns as a result of the coronavirus pandemic.
The Group’s Sports & Leisure division is 100% closed, while its

allows the operator to move the load to the desired position using both hands. In assembly mode, which is particularly suitable for joining components horizontally, any possible uncontrolled load movements are avoided, simplifying precision assembly processes. It also avoids potential damage due to collisions between components and, as a result, improves productivity.
The DCBS hoists also incorporate a load pick-up mode, which is useful for functions such as changing tools or removing parts from jigs or test benches. The balancer may be adjusted so that it only lifts until a predetermined force is reached. This enables load handling attachments to be lifted and pre-tensioned, allowing loads to be removed from a jig, without dropping or being suddenly pulled upwards.
The DCBS offers design features that simplify its operation, improve safety and reduce service requirements. These include its slipping clutch with automatic cut-out based on speed monitoring, which prevents permanent slipping in the event of overload. Because the brake is arranged in front of the slipping clutch in the load-bearing arrangement, any dropping of the load is prevented by applying the brake automatically, in the event of a malfunction. All operating modes are linked to additional protection
Education and Business & Industry divisions are 75% closed. Only the company’s Healthcare and Defence, Offshore and Remote divisions remain 100% in operation.
Compass reported it is proactively mitigating its cost base by around £450m per month by taking a wide range of actions including limited use of variable forms of in-unit labour such as over-time, contractors, and
functions, including adjustable load or speed limits for improved workplace safety.
DCBS models are particularly suited for use with the Demag KBK light crane system, creating integrated solutions for mobility and horizontal load transport. The hoists can travel on KBK profile section rails, single-girder suspension cranes or in system suspension monorails and slewing jib cranes.

temporary workers, and redeploying or furloughing much of the fixed element of its in-unit labour, reducing salary, hours or furloughed above- unit overhead employees.
The Chief Executive has also temporarily reduced his salary by 30%, whilst the Group Board and Executive Committee have temporarily reduced their fees and salaries by 25%.
